Due to the summer holidays, OSCON and a couple of people who normally contribute being ill, none of the regular contributors to document days were not around. As a consequence we had no contributions. This was followed by a discussion last week, I had with regular contributors to see what was going on. In a nutshell the key points that were made are: 1) For Hypervisor Docs, there are no more "low hanging fruit" left over. Even the regular contributors to document days, have difficulties figureing out which documents actually need to be improved 2) This makes it increasingly difficulkt for newbies to participate in document days 3) We have become better in creating documents for new features and for new releases 4) In recent document days, discussions on the IRC channel were more about making documents more accessible and easier to find, compared to To counter balance this, we do have areas which have weak wiki documentation. Notable areas are XAPI and Mirage: for these sub-projects we never really got much community participation. Another question is whether the fact that we had to lock down the wiki due to the recurring spam attacks, is having a negative impact on wiki contributions and document days in particular. All these points, raise the question whether a) we still need to have document days, and b) if we do, what we can do to increase participation. I wanted to start a discussion about this, before I make a proposal to kill document days, or maybe change them. Input is desired. If there is no input, that will add to the case for not having document days any more.

the different targets for the mirage libraries conflict and can't= be installed simultaneously in the same opam compiler switch.

the way that i deal with this is to have multiple compiler switches with th= e different mirage packages installed. i tried to explain this at the end o= f <http= ://openmirage.org/wiki/install> but now realise that it doesn't = flow into <http://openmirage.org/wiki/mirage-www> as neatly as it might.= i'll try and fix the install instructions so that it does!

basically-- the current compiler switch you're using has the mirage-xen= package installed which conflicts with the mirage-unix packages (mirage-ne= t-socket in this case). just "opam remove" the conflicting packag= es. in your case probably

$ opam remove mirage-xen

then

$ make unix-socket-build
$ make unix-socket-run

...should work, giving you a running instance of the openmirage website at = localhost:80 (or whatever port number is currently specified in ./src/www.c= onf).

using multiple compiler switches to manage this is pretty straightforward: = to build using the mirage network stack:

$ opam switch 4.00.1+mirage -a 4.00.1
$ eval $(opam config env)
$ make clean
$ make unix-direct-build
$ make unix-direct-run

...which should give you a running instance of openmirage website at 10.0.0.2:80 (or specified po= rt number as above).

then finally to build a xen vm:

$ opam switch 4.00.1+xen -a 4.00.1
$ eval $(opam config env)
$ make clean
$ make xen-build
$ make xen-run ## if appropriate :)

...which should result in openmirage website in a running vm.

there are a couple of ocaml openflow bindings

<= https://github.com/mirage/ocaml-openflow>
=A0 =A0 =A0 =A0 developed with mirage, for the ICC paper

<https://github.com/frenetic-lang/ocaml-openflow>
=A0 =A0 =A0 =A0 possibly more complete and actively developed, not checked<= br>
haris or anil probably know more about current status of these...

Hi Richard,

It looks like root doesn= 9;t know about 'mirari'?

'make unix-socket-build'= ; does not require 'sudo' and completed successfully.
'make unix-soc= ket-run' requires 'sudo' and failed.

looks like mirari package was only installed as a dependency for mira= ge-xen; when mirage-xen was removed, opam also removed mirari.

$ opam install mirari

...before "make unix-socket-build" should fix that.

a) Do you think we should have the meeting at all (i.e. do you think it is = valuable)?
b) Would you attend, if we have it?

It is invite only in the sense of the Hackathons, where we have limited space. What we do there is a) Anybody can request an invite b) If it somebody who is totally unknown in the community asks for an invite, we will likely put them onto a waiting list c) People who are known and have contributed will get an invite d) If we still have space we go through the waiting list and see how/whether they can fit in To answer your question: anybody who is active on these lists and wants to attend should be able to get a space. The only possibility where we don't have enough space is if say 20 people say they want to come replying to the thread, I book space for 30 and then 60 people request an invite. In practice this isn't likely though. Does this answer your question?

ok, i guess it'll be a sudo path inheritance thing then.

you could try changing the port in www.conf and removing the relevant "= ;sudo" line from the makefile to check i guess...

One casualty of this is OPAM, which normally installs binaries in = ~/.opam//bin and adds it to the user PATH. However, when you = are sudoing, the PATH is reset to the root default one, and thus mirari = (installed by OPAM) cannot be found. And when you don't sudo, you don't have sufficient privileges to open = the tuntap device. You can either fix this by giving yourself the right = capabilities from your normal user to access the relevant resource, or = by moving the mirari binary to somewhere visible within the global PATH = for root (e.g. /usr/local/bin/mirari). We should fix this in the Makefiles, but I'm not quite sure what the = best way to do this is, as Mirari is one of the only host tools that has = this problem.

Many more people should be available on the 6th. Making it Friday would give people a chance to get back into the groove after returning from a break. Earlier in the week might be problematic for people who just returned from time off, while any later in the month starts to encroach on the regularly scheduled September 30 Xen Docs Day. Anyone have a reason to leave it as is, or move it to another day?

You can find the code here: http://github.com/vbmithr/ocaml-vchan. Some packaging still need to be done in order to be able to quickly switch compilation between the UNIX backend and the Mirage backend. I encourage everybody interested in vchan to try it out! You will find a "vchan echo server" in test/node_mirage.ml. There is a mirari config file here that you can use to easily build it. Otherwise, node_cli.ml is for the UNIX backend, and it is equivalent to the vchan node test in the xen sources (tools/libvchan in Xen). For some reason, I have problems with Xen currently on my machine, but I encourage you to try to run the "node_mirage" server, and use node_cli (or the program in the Xen tree) to test it out.

I've created an iperf client and an iperf server based on the sources I found here: https://github.com/mirage/mirage-net/tree/master/direct/tests/iperf_self I've de-coupled the client from the server, and minimized I/O and per-packet processing between "Net.Flow.write" and "Net.Flow.read" calls, for saturating the network stack's throughput. The sources of the iperf server/client can be found here (I am using mirari): http://www.cl.cam.ac.uk/~dp463/files/iperf.tar.gz I have also written custom fail-safe scripts which automatically, create, configure, install and uninstall mirage Xen kernels (for XenServer XAPI), minimizing the time required to experiment with different kernels (PM me to provide you with those as well) The FIRST problem is that the iperf benchmark most of the times stalls and never completes, especially when I run mirage iperf client as a Xen guest (see EXPERIMENTS A, B). When the iperf client is compiled against unix, the benchmark manages to complete (see EXPERIMENTS C, D), but the speed is not impressive. The SECOND problem/observation, is that the datarates I obtain with mirage are quite low, especially when compared to Linux guests (near an order of magnitude difference). It might be the case that the network stack of mirage requires some manual tuning, or that my code is inefficient. If this is the case, feel free to provide me with your comments. The TCP settings of all linux guests (including dom0) are here: http://www.cl.cam.ac.uk/~dp463/files/linux.tcp.settings.txt Also, does anyone know which congestion control algorithm is implemented in the Mirage TCP stack? Ubuntu and Debian Linux uses Cubic by default. At the bottom of this email you can find the details of my setup and the benchmark methodology. I also include some benchmark results for various configurations. Thank you, Dimos =============================== *** Configuration Setup *** =============================== *** System Details *** - Machine specs: i7 3770, 4-core (8-threads), 32GB DDR3 1333 RAM *** Ocaml / Mirage *** - Fetched the latest versions of mirage, mirage-fs, mirage-net, mirage-net-direct, mirage-unix, mirari (all 1.0.0), from "opam-repo-dev" - Mirage iperf settings: Total data volume sent during a benchamrk: 8 gigabits (kilo is 1000, in other words 1000000000 bytes, ~640K [packets ) Packet size: 1461bytes Default TCP settings *** Xen / Linux *** - Xen Hypervisor 4.1 (Ubuntu 12.10, XCP, openvswitch, Xen API v1.3) - Xen vCPU allocations: Dom0: pinned on cores 0 and 1 (VCPUs-params:mask=0,2) Dom1: pinned on core 2 (VCPUs-params:mask=4) Dom2: pinned on core 3 (VCPUs-params:mask=6) - All Linux programs (e.g. mirari run --unix, iperf) run with "nice -n -15" *** Networking configuration *** - Using OpenVSwitch v1.4.3. for bridging - Default Linux TCP settings for Linux running on DomUs and Dom0 (see here: http://www.cl.cam.ac.uk/~dp463/files/linux.tcp.settings.txt) - No Jumbo frames for Xen: xe network-param-get uuid=a0378bc6-a9e4-9054-50ff-59d5ab8d2ee8 param-name=MTU --> 1500 - No Jumbo frames for Linux: All interfaces are set with 1500 butes MTU - For the Linux2Linux iperf experiments that run only on Dom0, the client and the server are forced to push traffic through xenbr0 (mtu1500) (not via loopback) - For the Mirage instances that are compiled for unix target, mirari creates a tap interface which I attach to bridge xenbr1. When I run 2 unix instances of mirage, I force them to communicate over 2 distinct tap interfaces, attached on the same bridge (xenbr1). I had to modify a bit mirari as it had "tap0" and "10.0.0.1" values hard-coded. =============================== *** Mirage2Mirage benchmarks *** =============================== ------------------------------------------------------ Experiment A: Xen.DomU( Mirage xen Iperf.Server ) Xen.DomU( Mirage xen Iperf.Client ) ------------------------------------------------------ Most of the times (around 7 out of 10) the experiment hangs, and it seems to me that the network stack is block-waiting. When the experiment hangs, the vCPUs utilisation are ~0% for DomUs, and ~100++% for Dom0. Also, I get a mixture of error messages which I attached right under the next paragraph. When the benchmark manages to complete, I get a huge variability in the throughput. Note that Dom0 and DomUs are pinned to exclusive vCPUs / physical cores, so the variabilty in performance can't be due to noise from other processes.

The FIRST problem is that the iperf benchmark most of the times stalls and = never completes, especially when I run mirage iperf client as a Xen guest (= see EXPERIMENTS A, B).
When the iperf client is compiled against unix, the benchmark manages to co= mplete (see EXPERIMENTS C, D), but the speed is not impressive.

The SECOND problem/observation, is that the datarates I obtain with mirage = are quite low, especially when compared to Linux guests (near an order of m= agnitude difference).

It might be the case that the network stack of mirage requires some manual = tuning, or that my code is inefficient. If this is the case, feel free to p= rovide me with your comments.
The TCP settings of all linux guests (including dom0) are here:

*** System Details ***
- Machine specs: =A0i7 3770, 4-core (8-threads), 32GB DDR3 1333 RAM

*** Ocaml / Mirage ***
- Fetched the latest versions of mirage, mirage-fs, mirage-net, mirage-net-= direct, mirage-unix, mirari (all 1.0.0), from "opam-repo-dev"
- Mirage iperf settings:
=A0 =A0Total data volume sent during a benchamrk: 8 gigabits (kilo is 1000,= in other words 1000000000 bytes, ~640K [packets )
=A0 =A0 Packet size: 1461bytes
=A0 =A0 Default TCP settings

*** Xen / Linux ***
- Xen Hypervisor 4.1 (Ubuntu 12.10, XCP, openvswitch, Xen API v1.3)
- Xen vCPU allocations:
=A0 =A0 Dom0: pinned on cores 0 and 1 (VCPUs-params:mask=3D0,2)
=A0 =A0 Dom1: pinned on core 2 (VCPUs-params:mask=3D4)

- All Linux programs (e.g. mirari run --unix, iperf) run with "nice -n= -15"

*** Networking configuration ***
- Using OpenVSwitch v1.4.3. for bridging
- Default Linux TCP settings for Linux running on DomUs and Dom0 (see here:= http://www.cl.cam.ac.uk/~dp463/files/linux.tcp.settings.txt)
- No Jumbo frames for Xen:

=A0 =A0 =A0 Xen.DomU( Mirage xen =A0Iperf.Client )
------------------------------------------------------
Most of the times (around 7 out of 10) the experiment hangs, and it seems t= o me that the network stack is block-waiting.
When the experiment hangs, the vCPUs utilisation are ~0% for DomUs, and ~10= 0++% for Dom0.
Also, =A0I get a mixture of error messages which I attached right under the= next paragraph.

When the benchmark manages to complete, I get a huge variability in the thr= oughput.
Note that Dom0 and DomUs are pinned to exclusive vCPUs / physical cores, so= the variabilty in performance can't be due to noise from other process= es.
Pushing 8 gigabits across the VMs takes anywhere from 6 seconds (~1.35Gbps)= to 20seconds (~0.4Gbps).

------------------------------------------------------
Most of the time the benchmark hangs, with the message "TCP retransmis= sion on timer seq =3D ...." shown either at the Client, or the Server = or both.
When the benchamrk completes, 8 Gigabits are transfered in about 8-9 second= s (0.9-1Gbps)

=A0 =A0 Experiment C:
=A0 =A0 =A0 Xen.DomU( Mirage xen =A0Iperf.Server )
=A0 =A0 =A0 Xen.Dom0( Mirage unix Iperf.client )
------------------------------------------------------
The benchamark always completes without any issues.
The client pushes to the server 8 Gigabits in around 10.2sec (~0.8 Gbps, qu= ite consistent)


------------------------------------------------------
=A0 =A0 Experiment D:
=A0 =A0 =A0 Xen.Dom0( Mirage unix =A0Iperf.Server )
=A0 =A0 =A0 Xen.Dom0( Mirage unix Iperf.client )
------------------------------------------------------
The benchmark always completes without hanging and/or errors.
It takes from 8seconds to 10 seconds to pushe 8 Gigabits from the client to= the server (0.8 - 1Gbps , quite consistent)

- Machine specs: =A0i7 3770, 4-core (8-threads), 32GB DDR3 1333 RAM

*** Ocaml / Mirage ***
- Fetched the latest versions of mirage, mirage-fs, mirage-net, mirage-net-= direct, mirage-unix, mirari (all 1.0.0), from "opam-repo-dev"
- Mirage iperf settings:
=A0 =A0Total data volume sent during a benchamrk: 8 gigabits (kilo is 1000,= in other words 1000000000 bytes, ~640K [packets )
=A0 =A0 Packet size: 1461bytes
=A0 =A0 Default TCP settings

*** Xen / Linux ***
- Xen Hypervisor 4.1 (Ubuntu 12.10, XCP, openvswitch, Xen API v1.3)
- Xen vCPU allocations:
=A0 =A0 Dom0: pinned on cores 0 and 1 (VCPUs-params:mask=3D0,2)
=A0 =A0 Dom1: pinned on core 2 (VCPUs-params:mask=3D4)
=A0 =A0 Dom2: pinned on core 3 (VCPUs-params:mask=3D6)
- All Linux programs (e.g. mirari run --unix, iperf) run with "nice -n= -15"

*** Networking configuration ***
- Using OpenVSwitch v1.4.3. for bridging
- Default Linux TCP settings for Linux running on DomUs and Dom0 (see here:= http://www.cl.cam.ac.uk/~dp463/files/linux.tcp.settings.txt)
- No Jumbo frames for Xen:
=A0 =A0 xe network-param-get uuid=3Da0378bc6-a9e4-9054-50ff-59d5ab8d= 2ee8 param-name=3DMTU =A0--> 1500
- No Jumbo frames for Linux:
=A0 =A0 All interfaces are set with 1500 butes MTU
- For the Linux2Linux iperf experiments that run only on Dom0, the client a= nd the server are forced to push traffic through xenbr0 (mtu1500) (not via = loopback)
- For the Mirage instances that are compiled for unix target, mirari create= s a tap interface which I attach to bridge xenbr1. When I run 2 unix instan= ces of mirage, I force them to communicate over 2 distinct tap interfaces, = attached on the same bridge (xenbr1). I had to modify a bit mirari as it ha= d "tap0" and "10.0.0.1" values hard-coded.

=A0 =A0 Experiment A:
=A0 =A0 =A0 Xen.DomU( Mirage xen =A0Iperf.Server )
=A0 =A0 =A0 Xen.DomU( Mirage xen =A0Iperf.Client )
------------------------------------------------------
Most of the times (around 7 out of 10) the experiment hangs, and it seems t= o me that the network stack is block-waiting.
When the experiment hangs, the vCPUs utilisation are ~0% for DomUs, and ~10= 0++% for Dom0.
Also, =A0I get a mixture of error messages which I attached right under the= next paragraph.

When the benchmark manages to complete, I get a huge variability in the thr= oughput.
Note that Dom0 and DomUs are pinned to exclusive vCPUs / physical cores, so= the variabilty in performance can't be due to noise from other process= es.
Pushing 8 gigabits across the VMs takes anywhere from 6 seconds (~1.35Gbps)= to 20seconds (~0.4Gbps).

=A0 =A0 Experiment B:
=A0 =A0 =A0 Xen.Dom0( Mirage unix Iperf.Server )
=A0 =A0 =A0 Xen.DomU( Mirage xen Iperf.client )
------------------------------------------------------
Most of the time the benchmark hangs, with the message "TCP retransmis= sion on timer seq =3D ...." shown either at the Client, or the Server = or both.
When the benchamrk completes, 8 Gigabits are transfered in about 8-9 second= s (0.9-1Gbps)


------------------------------------------------------
=A0 =A0 Experiment C:
=A0 =A0 =A0 Xen.DomU( Mirage xen =A0Iperf.Server )
=A0 =A0 =A0 Xen.Dom0( Mirage unix Iperf.client )
------------------------------------------------------
The benchamark always completes without any issues.
The client pushes to the server 8 Gigabits in around 10.2sec (~0.8 Gbps, qu= ite consistent)


------------------------------------------------------
=A0 =A0 Experiment D:
=A0 =A0 =A0 Xen.Dom0( Mirage unix =A0Iperf.Server )
=A0 =A0 =A0 Xen.Dom0( Mirage unix Iperf.client )
------------------------------------------------------
The benchmark always completes without hanging and/or errors.
It takes from 8seconds to 10 seconds to pushe 8 Gigabits from the client to= the server (0.8 - 1Gbps , quite consistent)

This is probably due to some optimizations to make all network traffic on the localhost not touching the network card (which is em(4) in this case) at all. The network layout of the machine currently is as follows (typical VBox NAT). Destination Gateway Netif default 10.0.2.2 em0 10.0.2.0/24 link#1 em0 10.0.2.15 link#1 lo0 127.0.0.1 link#2 lo0 And here is the network setup for the module to be tested, mir-ping [3], for example. ip-address: 10.0.2.215 ip-netmask: 255.255.255.0 ip-gateway: 10.0.2.2 That is, pinging 10.0.2.215 will not work in this setup: the Mirage module will not see any incoming frame and the FreeBSD stack will think that the host is down. I have talked about this a little bit with Bjoern Zeeb and he recommended to set a distinct MAC address for each of the Mirage modules. So (a) the frames will not looped back, (b) not all the traffic will be hijacked by the Mirage stack (in other cases), only the frames that are addressed to it, (c) this way multiple modules on the system can safely co-exist, including the FreeBSD networking stack. However, this implies somehow a unique MAC address has to be assigned to the module -- I did not find any way to do this in the mirari configuration, hence I guess this has to be generated automatically (and transparently). Bjoern told me that the FreeBSD kernel also has such routines implemented for other purposes, so I could piggyback on this probably. What do you think, are there any opinions, hints, recommendations on this?

Also, the discussion sessions at this year's Hackathon were very effective and popular. We are also having our first User Summit in September: so I expect that there will be less user content at the Developer Summit. I have booked two rooms for the Xen Developer summit, which means we have a number of options: Option 1) We could run two parallel content tracks for most of the event (assuming we have enough content) Option 2) We could use the second room for in-depth discussions (using an unconference scheduling mechanism as we have done at the Hackathon: if you want to know how this works do read http://blog.xen.org/index.php/2013/05/28/event-report-xen-hackathon-2013/ - we would use a simplified version of the mechanism described). These would run in parallel to the main program, for example in the afternoon. In other words, we would have "BoF type meetings decided on the day" or "hacking sessions" or "get started with X" or "how do we solve problem Z" etc. that would happen in the second room in parallel to talks.

This should be possible in the Mirari autogenerated portion -- you just need to use the (brand new) ocaml-ipaddr library to generate a local MAC and ensure that it's attached to the VIF. The details really depend on the kFreeBSD OS.Netif module -- right now, we only have ones for Xen and UNIX (tuntap). Do you have an implementation in the kFreeBSD branch at all?

Sounds good -- I am currently experimenting with dummy "virtual" MAC addresses, but I will switch to this library once the problem is solved. > The details really depend on the kFreeBSD OS.Netif module -- right > now, we only have ones for Xen and UNIX (tuntap). Do you have an > implementation in the kFreeBSD branch at all? Sure, I have. You can find (almost) the latest code I use in my git repository [1]. Though, it is missing the part I am currently working with, but I have extracted a work-in-progress version of it for you [2]. > We'd need a device bus and interrupts/Activations before we could hook up a full Netif > though. In the kFreeBSD backend, I am just sitting on top of the ether_input() and ether_output() functions to receive and send frames, and then I have those caml_get_mbufs() and caml_put_mbufs() functions to translate between cstructs and mbuf(9)s. (And the former is polled in certain intervals.) I am not sure if there should be more. Well, this experimental implementation above is able to answer ARP requests but it is stuck at receiving ARP replies at the moment. When pinging, it tries to figure out who to send the frame back, and issues an ARP probe with the target's IP address, but apparently does not receive an answer.

There is already so much going on that week with LKS and LinuxCon, XenSummit, and meeting other people in the halls - that having everybody in one room would make it much easier to have discussions.

However, one concern I have with 2) is, who's been listening to the talks from the main program in RoomA, if everyone is in RoomB having "fun" discussions? Wouldn't that raise fairness issues regarding which talks are scheduled to happen in parallel with the BoF sessions, as compared to the ones that are not? As I said, I liked it for the hackathon but that was, well, the hackathon...

I tend to agree, especially since I liked the hackathon format and outcome. However, one concern I have with 2) is, who's been listening t= o
the talks from the main program in RoomA, if everyone is in RoomB having "fun" discussions?

Wouldn't that raise fairness issues regarding which talks are scheduled=
to happen in parallel with the BoF sessions, as compared to the ones
that are not?

As I said, I liked it for the hackathon but that was, well, the
hackathon... In this case I fear it could be a bit both rude and
pointless to ask people to submit talks for the summit and then have
noone listening to the presentations, because everyone is in the room
next door! :-O

Or did I misunderstand something and there is no risk of that?

Also, won't the "let's have everyone in one room" be cove= red by the
Devs/Committers/Maintainers Meeting, of course, if we have one?

Thanks and Regards,
Dario

The only thing we will be competing with during XenSummit is LKS (which affects you and Stefano mainly) and ourselves. Automotive Linux Summit and ELCE (Embedded Linux Conf) is on, but the majority of us don't really have conflicts with these. KVM Forum has a harder time this year, overlapping with LC and CloudOpen. The Dev Meeting will be a little harder, but on Wed afternoon all the other events will start to frizzle out (with the exception of LKS which starts on the Wed).

Are you talking about _one_ BoF discussion at a time in the "other room" --as you say below-- or _several_ of them at the same time, still in the "other room", involving different group of people --as it was at the Hackathon? It might sound subtle, and it probably is, but I think it does make a difference (see below). > If there was one BoF discussion going on in parallel to the track in > the afternoon, I wouldn't expect that more than a dozen or so people > would come to a specific discussion.=20 > Yes, I think that too. > It'll create a degree of competition with the main program, but that > would exist also if we had two tracks.=20 > Well, it is indeed the same as having two tracks if we have, at any given time, *1* thing going on in room A (e.g., main talks track) and *1* thing going on in room B (e.g., one specific BoF/hacking session).

Fair enough. :-) BTW, there might be a quite fundamental
misunderstanding here. Are you talking about _one_ BoF discussion at a
time in the "other room" --as you say below-- or _several_ of the= m at
the same time, still in the "other room", involving different gro= up of
people --as it was at the Hackathon?

It might sound subtle, and it probably is, but I think it does make a
difference (see below).

Yes, I think that too.

Well, it is indeed the same =A0as having two tracks if we have, at an= y
given time, *1* thing going on in room A (e.g., main talks track) and
*1* thing going on in room B (e.g., one specific BoF/hacking session).
In this case, I agree with you, and most of my concerns would just
disappear.

OTOH, if there's a talk in room A and (even if just potentially), 10 BoFs in room B (it was like this at the Hackathon), then it looks like a way less fair competition to me. :-/

So, sorry if it's my fault not understanding this from the beginning, which one are we talking about?

talk, if the talk it's not interesting for them, and any attempt to do<= br> that will fail miserably, I concur with that, and I'm not asking for anything like this! :-P

Nevertheless, having visited quite some conferences during the past

think we at least should be really careful in making it clear how it
will be like, especially when we ask people to submit their talks and
come to Scotland to give the presentation, if accepted.

Personally, I haven't made up my mind about what the best option would be yet (and I will vote accordingly as soon as that will happen), but at least, with this clarification, the concerns I had about option 2 went away.

All right, I have figured out the causes and fixed it in the `Netif` module. Now I am able to ping the Mirage instance running inside the FreeBSD kernel. I have just pushed the code to my GitHub repository [1], albeit I still have to find a "double free()" bug somewhere around the garbage collector...

Hi,

Thank you for sharing.
I followed the instructions in Appendix A to install utop:

$ opam install utop

$ utop
Fatal error: cannot load shared library dlllwt-unix_s= tubs
Reason: dlllwt-unix_stubs.so: cannot open shared object file= : No such file or directory

Where can this s= hared library dlllwt-unix_stubs be found?

Regards,

PhiHo

Hi,

Thank you for sharing.

I followed the instructions in Appendix A to install utop:

$ opam install utop

$ utop
Fatal error: cannot load shared library dlllwt-unix_stubs
Reason: dlllwt-unix_stubs.so: cannot open shared object file: No such file or directory

Where can this shared library dlllwt-unix_stubs be found?

Yes, that works.
Thank you.
BTW, in my '.bash_profile', the OPAM configuration is a= lready in there:

# OPAM configuration
. ~/.opam/opam-init/init.sh > /dev/null 2> /dev/null || true

Now I need to add:

=A0eval `opam = config env`

Is that correct?

Can I run 'utop' from a putty console?

You'll need to check if your bash_profile is actually being execu= ted for an interactive shell (as bashrc may also take precedence). =A0Put a= n "echo" in there to debug it. =A0You shouldn't need the extr= a eval line if the above fragment is activated.

It should work, and thus make it much easier to develop libraries that depends on either mirage-platform or Unix's xenctrl library. In particular, this is a requirement for an easy cross unix/xen packaging of my ocaml-xenstore library. I'm going to test it as well ASAP, but I wouldn't mind other people trying it out too.

Dave pointed out that the mirage-unix package exports a OS.* namespace as w= ell. But certainly, the UNIX version of Xen libs would not exist behind OS = would they ?

The hack I was thinking of= was:

In your library write

=A0 open= OS
=A0 open Eventchn

and then link the = unix version against "mirage(-unix), xenctrl" and the xen version= against "mirage(-xen)". Under Unix the "open OS" is a = no-op and it will get Eventchn from xenctrl while and under xen the "o= pen OS" has the side-effect of unpacking the Eventchn from the OS modu= le.

Does that work & make sense?

The drawback is that is only works on Mirage kernels (as opposed to traditional UNIX ocaml programs that would like to use eventchn). A solution is to link mirage-unix even on programs that are not mirage unikernels. Not really perfect but OK for now. Thanks!

It depends what the nature of your crash is, but you basically want to = record the domain time at the beginning of the boot and stash it in a = local variable.

Hi,

I have followed the latest in= stallation instructions (Aug-10-2013):

http://openmirage.org/wiki/install

I - =A0got 2 compiler switches:
=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
$ opam= switch mirage-unix -a system
$ eval `opam config env`
= $ opam install mirari mirage-net-direct

$ opam switch mirage-xen -a system
$ eval `op= am config env`
$ opam install mirari mirage-xen
=

Question 1
=3D=3D=3D=3D=3D=3D=3D=3D
Is this OK or should I install one of them at a time, the first one is for= Unix backend and the second one for Xen Unikernel?

II - make unix-socket-build failed
=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
T= hen cloned mirage-www and tried to build mirage-www without success, becaus= e of conflict.
(Please see the console output appended below)

Question 2
=3D=3D=3D=3D=3D=3D=3D=3D
Why do I have so many conflicting packages:

=A0 - The package mirage-net-socket.0.9.1 is in conflict with mi= rage-net-direct.0.9.1.
=A0 - The package mirage-net-socket.0.9.1 is in conflict with mirage-n= et-direct.0.9.2.

=A0 - The package mirage-xen.0.9.2 is in conflict with mirage-unix.0.9= .1.
=A0 - The package mirage-xen.0.9.3 is in conflict with mirage= -unix.0.9.1.

III - make clean xen-buil= d failed
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D
I then tried to build the Website as a Xen Unikernel witho= ut success because 'install cow.0.6.2' failed because of this error= :

/usr/bin/ocamldep -pp camlp4orf -modules pa_ulex.ml > pa_ulex.ml.depends
+ /usr/bin/ocamldep -pp camlp4orf -modules pa_ulex.ml > pa_ulex.ml.depends
sh: 1: camlp4orf: not f= ound
Preprocessing error on file pa= _ulex.ml
Command exited with code 2.
make[2]: Leaving directory `/hom= e/phiho/.opam/mirage-xen/build/ulex.1.1'

Question3
=3D=3D=3D=3D=3D=3D=3D
Which opam package =A0= do I need to install to resolve this issue?

I really wish if I could successfully build a simple Xe= n Unikernel using mirari.

One casualty of this is OPAM, which normally installs binaries in ~/.opam/&= lt;compiler>/bin and adds it to the user PATH. =A0However, when you are = sudoing, the PATH is reset to the root default one, and thus mirari (instal= led by OPAM) cannot be found.

And when you don't sudo, you don't have sufficient privileges to op= en the tuntap device. =A0You can either fix this by giving yourself the rig= ht capabilities from your normal user to access the relevant resource, or b= y moving the mirari binary to somewhere visible within the global PATH for = root (e.g. /usr/local/bin/mirari).

We should fix this in the Makefiles, but I'm not quite sure what the be= st way to do this is, as Mirari is one of the only host tools that has this= problem. =A0Thomas, any thoughts on this "binary promotion"?

I then continue (from the &q= uot;Installation" page) with:

$ opam switch mirage-xen -a system
$ eva= l `opam config env`
$ opam install mirari mirage-xen

Then back to the 'Building =A0mirage-www' page:<= /div>

$ opam switch mirage-xen

the first is for the unix backend using the "direct" (mirag= e-on-tuntap) network stack; the second is for xen, also using the "dir= ect" network stack (the only one that we have on xen). you actually al= so have a third, your system's native "system" switch.

yes -- this will conflict because both of the switches you describe a= bove use the mirage "direct" network stack.

the instructions are supposed to have you end up with your "system&quo= t; switch having the packages for the unix backend with the native "so= ckets" network stack. apologies if that's not clear -- i'll go= back and reread the instructions.

those packages are all to do with trying to build for the socket netw= ork stack when you've the direct network stack packages installed -- th= ey conflict.

if you try something like

$ opam switch system
$ eval $(opam config env)
$ opam install mirari mirage-net-socket
$ make unix-socket-build

...you should find that works. (indeed, you should be able to leave out the= "opam install ..." line and it should work -- the makefile ought= to install any necessary packages.)

if that doesn't work due to package conflicts, then i suggest creating = a third mirage switch and using that, e.g.,

$ opam switch mirage-socket -a system
$ eval $(opam config env)
$ opam install mirage-unix mirage-net-socket mirari

...you should then be able to build the unix-socket version of mirage-www.<= br>

that one i'm not familiar with, and i'd need to dig my VM out= to test the mirage-xen switch as i'm on osx-- anyone else? the errors<= br>

it looks like there's a problem with the ulex.1.1 package, but i&= #39;m not very familiar with that package so not sure what to suggest.

hope that helps!

So you can't make new subdirectories and you can only write to a few miscellaneous places. The permissions have been set this way because it's normally the toolstack's job to create devices (backends and frontends) and introduce them to each other. Backend software running in privileged domains has (unfortunately) trusted the values in xenstore to have come from the toolstack -- rather than the untrusted frontend -- and this has led to some security vulnerabilities when the permissions were accidentally relaxed, and the frontend was able to change them. There's a general move towards trusting xenstore less and imposing security policies in the hypervisor via XSM. I think there are 3 options: 1. architect the application such that there is a toolstack (ie dom0) component which creates the directories to introduce client to server. This is what happens with the block and net protocols but may not be appropriate for vchan? 2. propose a canonical place where "vchan" endpoints should be advertised (/local/domain/$ID/vchan or /local/domain/$ID/device/vchan), and modify the toolstack to make the directory and 'setperm' it. 3. use one of the places you can already write to. Looking at the default permissions above the only options are: >>>> ... event-channel = "" . . . . . . . . . . . . . . . . . . . . (n7) ... shutdown = "" . . . . . . . . . . . . . . . . . . . . . . .

We will resume our normal Xen Document Day schedule in September. Of course, if you wish to work on documentation on August 26, please go right ahead. But we won't be asking for people to pitch in and help, given that a significant number of contributors won't be available on that day. Thank you, and I hope those of you on vacation/holiday will have a refreshing time off.

I'm building a Xen kernel against a locally modified "mirage-platform"=20 repository, which is a few versions behind the latest. When I build=20 with mirari, it pulls in "mirage-net" (though I don't use it and it's=20 not in my mirari config file), and I can't find any way to put a version = constraint on the dependency. I need to install a slightly older=20 version of "mirage-net" that compiles cleanly with my local=20 "mirage-platform" repository. I can fix this by putting a package like "mirage-net.999" or something=20 in my local OPAM repository but this feels like a pretty unprincipled=20 solution. Is there a better way to tell mirari that I want=20 "mirage-net.0.9.2" instead of whatever the latest is? Or tell it not to = pull in mirage-net at all? (Also, I tried pinning mirage-net to 0.9.2 with OPAM but that seemed to=20 want to downgrade a lot of packages and break the whole world... Plus,=20 since that's an extra step that's not part of the build, it's hard to=20 automate even if it was doing what I wanted.) Thanks!

It looks like mirari pulls in the network=20 backend unconditionally. I've attached a quick patch that seems to fix=20 this for me by not adding the dependency for noip builds. I do think it's unfortunate that there's no way to put version=20 constraints on dependencies that are added by the build tool, but that's = a larger issue. :) Thanks, James On 08/21/2013 01:17 PM, Dave Scott wrote: > Hi, > > Is it pulling it in because your project's .conf file mentions an IP ad= dress or DHCP?

I'm not very sure how we should fix that. I guess the answer is to implement an OCaml memory management instead of asking MiniOS to allocate memory for us. But what partical implementation of a MM, I don't know. I think this problem should be addressed quickly. Is this a regression ?

The setup is as follows: I have two linux VMs each connected to a bridge (xapi1 and xapi2) which run iperf to measure network performance. In order to bridge the two VMs I am running a third VM, which can be interchangably a VM running openvswitch or a Mirage Switch, which is allocated a vif attached to each of the vifs. The switch VM simply bridges traffic between the two VMs. Comparing the mirage switch with the ovs I have observed the folloiwng behaviour. When I am running an openvswitch DumU switch I am able to switch between two vms approx. 1G of udp traffic using iperf. In order to simulate a similar behaviour, I have written a small mirage app which bridges traffic between 2 vifs. During the Manager.create callback, for each vif I register a promiscuous callback for each vif using the set_promiscuous Manager method. The callback receives a packet for one of the ports and forwards it to the other port, using the inject packet method of the Manager. These methods hook on the OS.Ethif module and listen or write for packets directly on the OS.Netif entity. A first thing I observed with Mirage was that beyond 700Mbps the VM crashes because it runs out of memory. This behaviour I think is related to the logic of the listen method which spawns a new thread for each packet received. If the thread creation rate is lower than the packet processing rate, then the VM cannot fulfil the memory requirements and dies. This is easily solvable using a capped Lwt_stream which functions as a NIC rx queue. Using this trick I managed to solve the memory sortage problem. Now my next problem is that the VM cannot switch more that 700Mbps, while the CPU utilisation is maximum 60% during execution. I inserted some counter in the code and noticed that the tx ring tends to drop some packets (I compare the number of packet I inject to the vif with the number of packets observed on the end host of the iperf test). I have verified using tc and ifconfig that these packets are not lost in between the vif during the switching process (you need to do a bit of configuration in the txqueuelen in order to ensure that packets are not dropped). My guess so far is that the performance bottleneck is on the TX ring of the vif. Are there any hints on how I could improve the performance or any ideas on the bottleneck point? -- Charalampos Rotsos PhD student The University of Cambridge Computer Laboratory William Gates Building JJ Thomson Avenue Cambridge CB3 0FD Phone: +44-(0) 1223 767032 Email: cr409@cl.cam.ac.uk From anil@recoil.org Mon Aug 26 12:07:16 2013 Received: from ppsw-52.csi.cam.ac.uk ([131.111.8.152]) by lists-2.csi.cam.ac.uk (lists.cam.ac.uk [131.111.8.15]:25) with esmtp id 1VDudg-00015F-4v (Exim 4.70) for cl-mirage@lists.cam.ac.uk (return-path ); Mon, 26 Aug 2013 12:07:16 +0100 X-Cam-SpamDetails: score 0.0 from SpamAssassin-3.3.2-1517252 X-Cam-ScannerInfo: http://www.ucs.cam.ac.uk/email/scanner/ Received: from recoil.dh.bytemark.co.uk ([89.16.177.154]:23360 helo=dark.recoil.org) by ppsw-52.csi.cam.ac.uk (mx.cam.ac.uk [131.111.8.148]:25) with smtp id 1VDudf-0005z7-EG (Exim 4.80_167-5a66dd3) for cl-mirage@lists.cam.ac.uk (return-path ); Mon, 26 Aug 2013 12:07:16 +0100 Received: (qmail 24815 invoked by uid 634); 26 Aug 2013 11:07:15 -0000 X-Spam-Level: * X-Spam-Status: No, hits=-1.0 required=5.0 tests=ALL_TRUSTED X-Spam-Check-By: dark.recoil.org Received: from cpc7-cmbg14-2-0-cust238.5-4.cable.virginmedia.com (HELO [192.168.1.99]) (86.30.244.239) (smtp-auth username remote@recoil.org, mechanism cram-md5) by dark.recoil.org (qpsmtpd/0.84) with ESMTPA; Mon, 26 Aug 2013 12:07:14 +0100 Content-Type: text/plain; charset=us-ascii Mime-Version: 1.0 (Mac OS X Mail 6.5 \(1508\)) Subject: Re: raw netif performance enhancement From: Anil Madhavapeddy In-Reply-To: <20130826082928.GB94958@haris-mac.cl.cam.ac.uk> Date: Mon, 26 Aug 2013 12:07:18 +0100 Content-Transfer-Encoding: quoted-printable Message-Id: References: <20130826082928.GB94958@haris-mac.cl.cam.ac.uk> To: Charalampos Rotsos X-Mailer: Apple Mail (2.1508) X-Virus-Checked: Checked by ClamAV on dark.recoil.org Cc: cl-mirage@lists.cam.ac.uk X-BeenThere: cl-mirage@lists.cam.ac.uk X-Mailman-Version: 2.1.8 Precedence: list List-Id: MirageOS development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 26 Aug 2013 11:07:16 -0000 Content-Length: 2997 Lines: 80 On 26 Aug 2013, at 09:29, Charalampos Rotsos wrote: >=20 > A first thing I observed with Mirage was that beyond 700Mbps the VM = crashes > because it runs out of memory.

The OCaml compiler installation is not relocatable -- that is, once you install it in a PREFIX, it must stay there. This is because the directory is hardcoded into the compiler driver ("ocamlc -where"). So I suspect the reason this failed for you on NixOS is because of the tricks it plays with symlinks in order to have multiple simultaneous package revisions. I haven't had a chance to try NixOS out for myself to verify this yet. -- Anil Madhavapeddy http://anil.recoil.org From avsm@dark.recoil.org Fri Aug 30 14:42:02 2013 Received: from ppsw-32.csi.cam.ac.uk ([131.111.8.132]) by lists-2.csi.cam.ac.uk (lists.cam.ac.uk [131.111.8.15]:25) with esmtp id 1VFOxe-0005JF-Tx (Exim 4.70) for cl-mirage@lists.cam.ac.uk (return-path ); Fri, 30 Aug 2013 14:42:02 +0100 X-Cam-SpamDetails: score 0.0 from SpamAssassin-3.3.2-1518538 X-Cam-ScannerInfo: http://www.ucs.cam.ac.uk/email/scanner/ Received: from recoil.dh.bytemark.co.uk ([89.16.177.154]:37769 helo=dark.recoil.org) by ppsw-32.csi.cam.ac.uk (mx.cam.ac.uk [131.111.8.146]:25) with smtp id 1VFOxe-0002Vi-11 (Exim 4.80_167-5a66dd3) for cl-mirage@lists.cam.ac.uk (return-path ); Fri, 30 Aug 2013 14:42:02 +0100 Received: (qmail 10100 invoked by uid 10000); 30 Aug 2013 13:42:01 -0000 Date: Fri, 30 Aug 2013 14:42:01 +0100 From: Anil Madhavapeddy To: Lars Kurth Subject: Re: [Xen-API] Xen Developer Summit (Oct 24-25 Edinburgh): CFP reminder (ends Aug 30) Message-ID: <20130830134201.GK17406@dark.recoil.org> References: <51FF8F2F.8020002@xen.org> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <51FF8F2F.8020002@xen.org> User-Agent: Mutt/1.5.21 (2010-09-15) Cc: cl-mirage@lists.cam.ac.uk X-BeenThere: cl-mirage@lists.cam.ac.uk X-Mailman-Version: 2.1.8 Precedence: list List-Id: MirageOS development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 30 Aug 2013 13:42:03 -0000 Content-Length: 1335 Lines: 35 [Dropping CC to Mirage list only] Just to let the rest of the team know, I've submitted a talk proposal based on Dave's "building custom block devices" post.
