Not yet; you have to use the Mirage base module which provides the OS abstr= action.

Hello Dave,

thanks for your reply.

When I understood you right, this rule is not needed:

# Xe=
nstore requires the global VIRQ for domain destroy operations
allow dom0_t xenstore_t:domain set_virq_handler;
So it would be= possible to shutdown a guest from within the guest but not via for example= xl shutdown and xl destroy am I right?

Best Regards

Hi,

I've not tried configuring XSM/FLASK yet but I do know it's only ne= cessary for the domain getinfo hyper call, which is only necessary to detec= t domain shutdown (and that a ring should be shutdown). Without it everythi= ng will work but you'll slowly leak memory.

Unikernels = are single-purpose appliances that are compile-time specialised into = standalone kernels, and sealed against modification when deployed to a = cloud platform. In return they offer significant reduction in image = sizes, improved efficiency and security, and should reduce operational = costs.

=A0<= /p>

Oh yes the VIRQ handle= r too =96 I=92d forgotten about that one. So I think you need:

1.=A0=A0=A0=A0=A0=A0 The right to install a DOM= _EXC VIRQ handler: xen will signal this event channel whenever a domain shu= ts down; and

2.=A0=A0=A0=A0=A0=A0 The right to call domain_g= etinfo: xenstored will need this to figure out *which* domain has sh= utdown.

=A0<= /p>

If you figure out the = correct runes to set this up then please let me know, it would save me some= time later! J In my testing I just tole= rated the bugs triggered by this.

=A0<= /p>

I think your analysis = is correct. If xenstore can=92t detect a domain shutdown then:

1.=A0=A0=A0=A0=A0=A0 It won=92t free the ring, = which will prevent the domain being fully cleaned up (it will remain in =91= Dying=92 forever)

2.=A0=A0=A0=A0=A0=A0 It won=92t emit the @relea= seDomain watch, which is how a toolstack notices a domain has shutdown

So I think the guest will= shut itself down internally ok, but the cleanup will block, which will con= fuse toolstacks like xl.

Hi,=

=A0<= /p>

Oh yes the VIRQ handle= r too =96 I=92d forgotten about that one. So I think you need:

1.=A0=A0=A0=A0=A0=A0 The right to install a DOM= _EXC VIRQ handler: xen will signal this event channel whenever a domain shu= ts down; and

2.=A0=A0=A0=A0=A0=A0 The right to call domain_g= etinfo: xenstored will need this to figure out *which* domain has sh= utdown.

=A0<= /p>

If you figure out the = correct runes to set this up then please let me know, it would save me some= time later! J In my testing I just tole= rated the bugs triggered by this.

=A0<= /p>

I think your analysis = is correct. If xenstore can=92t detect a domain shutdown then:

1.=A0=A0=A0=A0=A0=A0 It won=92t free the ring, = which will prevent the domain being fully cleaned up (it will remain in =91= Dying=92 forever)

2.=A0=A0=A0=A0=A0=A0 It won=92t emit the @relea= seDomain watch, which is how a toolstack notices a domain has shutdown

So I think the guest will= shut itself down internally ok, but the cleanup will block, which will con= fuse toolstacks like xl.

When I understood you= right, this rule is not needed:

So it would be possible t= o shutdown a guest from within the guest but not via for example xl shutdow= n and xl destroy am I right?

Hi,

I've not tried configuring XSM/FLASK = yet but I do know it's only necessary for the domain getinfo hyper call= , which is only necessary to detect domain shutdown (and that a ring should= be shutdown). Without it everything will work but you'll slowly leak m= emory.

I've not tried configuring XSM/FLASK = yet but I do know it's only necessary for the domain getinfo hyper call= , which is only necessary to detect domain shutdown (and that a ring should= be shutdown). Without it everything will work but you'll slowly leak m= emory.

It should be a very pleasant place in November even if there is early snow. SOSP and PLOS (SOSPPLOS? SOSP for the goose is a PLOS-up for the gander) should be a worthwhile trip for some.

While all the libraries are in reasonable shape (just = need documentation), the process of configuring and building Mirage = applications is still difficult. =20 The reason for this is an intrinsic part of the Mirage philosophy: the = library OS model requires that libraries hold the mechanisms to do = things, with the policy in the application itself. In practise of = course, this means hardcoding things like network configuration in your = web server, or shell scripts to crunch up filesystems into static ML = modules. This needs cleaning up: in addition to the Xen backend, we also have a = fledgling FreeBSD kernel module, a Javascript layer, an NS3 simulator, = an HVM MiniOS which should run on KVM with a bit of hacking, and soon a = uBoot-based Raspberry Pi port! We are also beginning work on building = real systems using Mirage, as well as working on distributed = infrastructure to coordinate many Xen instances. So Thomas and I have been hacking on Mirari, which takes a single = configuration file and splits the lifecycle of a Mirage application into = three distinct segments: * configuration: it scans the config file, checks for any missing OPAM = packages, and installs them if missing. It also looks for any = filesystem directives and calls mir-crunch to generate the static ML = files. All of this is glued together into an autogenerated main.ml = which is the entry point for the application. * build: it runs the OCaml build (via Vincent's obuild), and then issues = any backend-specific commands (such as the Xen link, ocamlclean, or = whatever else we dream up). * run: this is yet to be implemented, and the reason for this mail. = Running a Mirage application is quite stateful: in the case of Xen, we = want to monitor the kernel, attach a console, and so on. Similarly for = UNIX, one can imagine the socket version opening up a control channel = for Mirari to listen on. An in the kFreeBSD backend, this would be done = via ioctls or other kernel/user interfaces. So I'm going to extend Mirari to add `run` support which is stateful. = Each run will give the application a unique ID, stored locally, and = enough information to poll the particular instance.

Google Talk is a downloadable Windows* application that offers:
- Free calls over your computer anytime, from anywhere, and for as long as = you want
- A simple and intuitive user interface for sending instant messages or mak= ing calls--no clutter, pop-ups or ads
- Superior voice quality through just a microphone and computer speaker
- Fast file transfers with no restrictions on file type

After signing-up, download Google Talk and sign in with your new Google Acc= ount username and password.
You can then begin inviting anyone you want to talk to for free.

Google Talk works with any computer speaker and microphone, such as the one= s built-in to many PC laptops today,
as well as with wired and wireless headsets and USB phones. Google Talk als= o works across all firewalls.

Google Talk is still in beta. Just like with Gmail, we're working hard = to add features and make improvements,
so we might also ask for your comments and suggestions periodically. We app= reciate your help in making it even better!

Thanks,

The Google Talk Team

So, in the setting, the idea would be: * let opam-repo-dev as is, but change the versions to "dev" and/or add = "dev: true" in the OPAM files * make dev version always lesser than normal versions, so that the = solver will not pick them in normal usage * use 'opam pin dev' if one wants to pin a package to its dev = version * add an umbrella dev package, with hard-constraints on all the dev = versions, so that 'opam install mirage-dev' will force install all the = dev packages if one wants to have all the dev packages. This will not necessary help to have more stable packages, but if you = think it's worth doing this this can be done without too much trouble I = think.

Hey Steve! Thanks for the reminder...I've yank the 3.12.1 compile= rs from the OPAM repository, as they're now well deprecated. =A0The swi= tch to 4.x was quite easy, and there are many, many performance and stabili= ty improvements in the new tree.

I'd recommend 4.01.0dev+mirage-xen to play with. =A0It gives you the tr= unk version with new compiler intrinsics that Pierre put in to optimise han= dling of low-level int16/32/64s. =A0It'll be what the first alpha relea= se uses.

I switched to 4.01.0dev+mirage-unix=A0b= ut it looks like xenstore is requiring a newer version of cstruct than is p= rovided?

Is `mirage` the correct thing to insta= ll if I want to build a mirage app? I notice that mirage-www is not in OPAM= any longer.

The overall interface should still be considered beta and subject to = change (see the TODO). 0.7.0 (25-Feb-2013): * Add zero-copy conversion functions to/from the Core `Bigsubstring`. * Add an `of_string` function to simplify the construction from OCaml = values. * Add Async interface to interoperate with Jane Street Core code. 0.6.2 (08-Feb-2013): * Add experimental `cstruct.obuild` for the `obuild` build tool. * Use bounds checked version of all functions in the external interface. * Expose the `Cstruct.debug` to dump internal state of a buffer to a = string. * Add `set_len` and `add_len` to manipulate the total-length field = directly. -anil= From amc79@cam.ac.uk Mon Feb 25 17:33:17 2013 Received: from ppsw-42.csi.cam.ac.uk ([131.111.8.142]) by lists-2.csi.cam.ac.uk (lists.cam.ac.uk [131.111.8.15]:25) with esmtp id 1UA1vQ-0002GC-Tf (Exim 4.70) (return-path ); Mon, 25 Feb 2013 17:33:16 +0000 X-Cam-AntiVirus: no malware found X-Cam-ScannerInfo: http://www.cam.ac.uk/cs/email/scanner/ Received: from dhcp-128-232-143-169.eduroam.csx.cam.ac.uk ([128.232.143.169]:61620) by ppsw-42.csi.cam.ac.uk (smtp.hermes.cam.ac.uk [131.111.8.159]:587) with esmtpsa (PLAIN:amc79) (TLSv1:AES128-SHA:128) id 1UA1vQ-0006P7-9K (Exim 4.80_167-5a66dd3) (return-path ); Mon, 25 Feb 2013 17:33:16 +0000 From: Amir Chaudhry Content-Type: text/plain; charset=windows-1252 Content-Transfer-Encoding: quoted-printable Subject: OCaml Labs Meeting - 8th March at 2pm in the Computer Lab Date: Mon, 25 Feb 2013 17:33:18 +0000 Message-Id: <9C034B82-D570-4443-80CD-AFC9EAF25417@cam.ac.uk> To: "cl-ocamllabs@lists.cam.ac.uk" Mime-Version: 1.0 (Mac OS X Mail 6.2 \(1499\)) X-Mailer: Apple Mail (2.1499) Cc: Mirage List 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, 25 Feb 2013 17:33:17 -0000 Content-Length: 573 Lines: 24 Dear all, The next OCaml Labs meeting will take place on the 8th of March.=20 Location information is below and the meeting agenda will follow later = this week. =20 Please do let me know if you will be attending. -- Details -- OCaml Labs Meeting 8th March 2013 2pm =96 3:30pm (but aiming for 3pm finish) Room FW26 - Cambridge Computer Laboratory William Gates Building JJ Thomson Avenue Cambridge CB3 0FD Best wishes, Amir PS If you'd like to subscribe to an iCal feed of OCaml Labs events, = please use the following link: webcal://talks.cam.ac.uk/show/ics/41277= From anil@recoil.org Wed Feb 27 09:09:29 2013 Received: from ppsw-50.csi.cam.ac.uk ([131.111.8.150]) by lists-2.csi.cam.ac.uk (lists.cam.ac.uk [131.111.8.15]:25) with esmtp id 1UAd0z-00064k-BP (Exim 4.70) for cl-mirage@lists.cam.ac.uk (return-path ); Wed, 27 Feb 2013 09:09:29 +0000 X-Cam-AntiVirus: no malware found X-Cam-SpamDetails: score 0.0 from SpamAssassin-3.3.2-1450078 * 0.0 URIBL_BLOCKED ADMINISTRATOR NOTICE: The query to URIBL was blocked. * See http://wiki.apache.org/spamassassin/DnsBlocklists#dnsbl-block * for more information. * [URIs: github.com] X-Cam-ScannerInfo: http://www.ucs.cam.ac.uk/email/scanner/ Received: from recoil.dh.bytemark.co.uk ([89.16.177.154]:25314 helo=dark.recoil.org) by ppsw-50.csi.cam.ac.uk (mx.cam.ac.uk [131.111.8.147]:25) with smtp id 1UAd0y-0000hU-sN (Exim 4.72) for cl-mirage@lists.cam.ac.uk (return-path ); Wed, 27 Feb 2013 09:09:29 +0000 Received: (qmail 27315 invoked by uid 634); 27 Feb 2013 09:09:28 -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 [192.168.1.84]) (86.30.244.239) (smtp-auth username remote@recoil.org, mechanism cram-md5) by dark.recoil.org (qpsmtpd/0.84) with ESMTPA; Wed, 27 Feb 2013 09:09:27 +0000 Content-Type: text/plain; charset=iso-8859-1 Mime-Version: 1.0 (Mac OS X Mail 6.2 \(1499\)) Subject: Re: the profiling patch From: Anil Madhavapeddy In-Reply-To: Date: Wed, 27 Feb 2013 09:09:26 +0000 Content-Transfer-Encoding: 7bit Message-Id: References: <9022E254-4804-4630-9CF8-EFA7C213F58C@recoil.org> To: Mark Shinwell X-Mailer: Apple Mail (2.1499) X-Virus-Checked: Checked by ClamAV on dark.recoil.org Cc: "cl-mirage@lists.cam.ac.uk List" 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: Wed, 27 Feb 2013 09:09:29 -0000 Content-Length: 1588 Lines: 62 Thanks, I'm CCing cl-mirage in case anyone else has time to try out Mark's amazing new native code profiling support.

I've merged all the latest changes into http://github.com/mirage/mirari -- let's use that instead of Thomas' repository for pull requests from now on. I think we're ready to start moving all the docs on the website over to Mirari now. Do you have your Xen kernels all working now Vincent? There's one main thing missing from Mirari now: the run target to execute the kernel. Some hacks to beware of: - In the UNIX backend, in mirage-platform/unix/runtime/tap_stubs_*.c, we currently hardcode an `ifconfig 10.0.0.1` to give the tap device a static IP address. This has made it easy so far to get networking up and running, but the tap device setup really ought to be done by Mirari-run instead of the Mirage-platform libraries (which should just open a tun passed to them). - In the Xen backend, we need to generate a config file that also includes the bridge information for the VIF. Right now the mirari.conf file doesn't include the bridge (only the IP address/DHCP), so it will need to be added as part of run support. - libvirt seems to be the best option to actually execute the kernel. Has anyone tried this yet -- Dave? On the configuration/build side, I've been thinking that Mirari should also run the compiler directly using the 4.01.0+mirage-xen switch. This will let the developer have their normal OPAM switch be one that can generate UNIX binaries (and also let Mirari depend on Core/Async/etc which can be part of the host toolchain and not the Xen one). Thomas: what's the best way to get OPAM support for this... I guess we need a way to spawn a subshell under a particular switch: e.g.: $ opam config env -s 4.01.0+mirage-xen That would then call obuild which would work correctly.

Do you have your Xen kernels all working now Vincent? Hi. I just joined the cl-mirage mailing list, so you don’t have to CC me anymore. No, I have a problem with the UNIX backend, the function pcap_opendev is not implemented in Linux. I have tried to implement that this afternoon, only to find out in the end that this was not straightforward (pcap_open_live returns a pcap_t * and not a fd). I did not have the time to inquire further. I spent hours trying to make the buildsystem (which is based on a cmd script + ocamlbuild/custom myocamlbuild -- maybe we should port that on obuild ?) link the resulting libs with pcap (-lpcap). I did not manage to do that either, wasn’t proficient enough in ocamlbuild scripting. So because of that, the tcp example in mirage-skeleton do not work in UNIX (and #require "mirage";; in utop fails as well because of pcap_opendev not implemented/linked). I have taken good note of your comments about mirari run and I will try to figure out a solution for that. Cheers !

You can compile dependencies in another switch using:

opam install foo bar --switch=3D4.01.0+mirage-xen

And then you can indeed compile your project with the command you gave.

That's correct: we currently don't have a way to spawn a subs= hell with the environment variables for a different switch. =A0Note that th= e subshell does *not* need to call OPAM, only obuild.

Thomas, I (think) this is what our friend in https://github.com/OCamlPro/opa= m/issues/482 wanted :-)

Yes, in addition to bei= ng less evil, I think that would allow us to do:

$ `opam = config env-variables` some command

With those variables i= n the environment for "some command".
