This should be the way, in my understandig too, but unfortunately after
installing the pfx certificates to my windows10 local machine cert
store, the drivers were still not working.

I had to stay with TESTSIGNING to make it work. I wonder what the
problem could be.

PV drivers are working well, I'm using it on several Windows 10
machines. I just posted a message about how to install them,

The only issue is now that they work only when TESTSIGNING is on.

This should be the way, in my understandig too, but unfortunately after
installing the pfx certificates to my windows10 local machine cert
store, the drivers were still not working.

I had to stay with TESTSIGNING to make it work. I wonder what the
problem could be.

PV drivers are working well, I'm using it on several Windows 10
machines. I just posted a message about how to install them,

The only issue is now that they work only when TESTSIGNING is on.

Before I do this though, I wanted to let you know that the 2016 Developer Summit will most likely be in Berlin in October (I am in the process of finalising space, budget and contract details which will need to be approved by the Advisory Board). We do have two options for a Hackathon: China (either Shanghai, Hangzhou or Beijing - details TBC) and Cambridge, UK. We are still in the early planning phase and the budget for the Hackathon has not yet been approved. Do let me know of your preference, and I will see whether I can work with the vendor(s) who are willing to host the 2016 Hackathon and choose a location, which suits a majority of developers.

I had originally had booked the space and all looked fine when it was originally arranged several months ago. Seems that the LinuxCon organisers tripped over a German holiday and had not accounted for it. I would like to get your input before the next board meeting in 10 days, such that I have community input for the meeting and I can make a swift decision at the meeting. We have the following options * Hold it on Monday Oct 3 - to Tue Oct 4 : the problem is that Oct 3 is a public holiday in Germany, which would affect German participants * Do a 1 day event only on Oct 4 : I don't think this is practicable * Hold the event alongside LinuxCon in Toronto in August, but then we'd have a Dev Summit in the US for 3 years in a row. On the plus side, it will be Linux' 25th birthday Other options, such as holding the event on its own will be too expensive. Please let me know your opinions.

It turns out that Monday, October 3, 2016 is German Unity Day and we've decided it will not be a good idea to hold LinuxCon on this day. So we are moving LinuxCon/ContainerCon to Tuesday, Wednesday, Thursday of that week and ELC-E will be Thursday & Friday as scheduled. This means that we have absolutely no additional space on Thursday. In addition, the space we do have in terms of larger rooms on Tuesday and Wednesday is extremely limited. We went through all the space yesterday, and we don't have any extra rooms that fit over 50ppl available on Tuesday & Wednesday. Thus, holding Xen Summit overlapping in Berlin at the same venue isn't going to work. The only real option for larger rooms in Berlin would be on Monday (but not on Tuesday, and again this is a holiday). > > We can co-locate in Toronto in August but only on the two days after LinuxCon/ContainerCon - Thursday and Friday (but we can do your board meetings on Wednesday).

It turns out that Monday, October 3, 2016 is German Unity Day and we've decided it will not be a good idea to hold LinuxCon on this day. So we are moving LinuxCon/ContainerCon to Tuesday, Wednesday, Thursday of that week and ELC-E will be Thursday & Friday as scheduled. This means that we have absolutely no additional space on Thursday. In addition, the space we do have in terms of larger rooms on Tuesday and Wednesday is extremely limited. We went through all the space yesterday, and we don't have any extra rooms that fit over 50ppl available on Tuesday & Wednesday. Thus, holding Xen Summit overlapping in Berlin at the same venue isn't going to work. The only real option for larger rooms in Berlin would be on Monday (but not on Tuesday, and again this is a holiday). > > > > We can co-locate in Toronto in August but only on the two days after LinuxCon/ContainerCon - Thursday and Friday (but we can do your board meetings on Wednesday).

It turns out that Monday, October 3, 2016 is German Unity Day and we've decided it will not be a good idea to hold LinuxCon on this day. So we are moving LinuxCon/ContainerCon to Tuesday, Wednesday, Thursday of that week and ELC-E will be Thursday & Friday as scheduled.

My xenstore key is: /a/path/to/a/key = "" In xs.c in the xen source: char *val = xs_read(xsh, xth, argv[optind], &len); if (val == NULL) { warnx("couldn't read path %s", argv[optind]); return 1; } So a NULL return value is used to indicate that the key does not exist. Testing this: # xenstore-read /a/path/to/a/key ; echo $? 0 # # no output or error However reading the same key on Windows through wmi instead results in python getting a None type object where I believe it should get an empty string "". Setting up a connection in Python through wmi to xenstore then: >>> print session.GetValue("/a/path/to/a/key") (None,) In powershell: PS C:\>$base = gwmi -n root\wmi -cl XenProjectXenStoreBase PS C:\>$sid = $base.AddSession("MyNewSession") PS C:\>$session = gwmi -n root\wmi -q "select * from XenProjectXenStoreSession where SessionId=$($sid.SessionId)" PS C:\>$v = $session.GetValue("/a/path/to/a/key").value PS C:\>echo $v.getType(); You cannot call a method on a null-valued expression.

I have tried to follow the xen source code and I didn't find any special NULL -> "" conversion in the read path but it is quite possible I have missed something. Therefore I believe that SessionExecuteGetValue() of wmi.c should be doing something special so there is compatibility in its behaviour between operating systems.

Setting up a connection in Python through wmi to xenstore then: >>> print session.GetValue("/a/path/to/a/key") (None,) In powershell: PS C:\>$base = gwmi -n root\wmi -cl XenProjectXenStoreBase PS C:\>$sid = $base.AddSession("MyNewSession") PS C:\>$session = gwmi -n root\wmi -q "select * from XenProjectXenStoreSession where SessionId=$($sid.SessionId)" PS C:\>$v = $session.GetValue("/a/path/to/a/key").value PS C:\>echo $v.getType(); You cannot call a method on a null-valued expression. At line:1 char:1 + echo $v.getType() + ~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (:) [], RuntimeException + FullyQualifiedErrorId : InvokeMethodOnNull PS C:\>echo "".getType() IsPublic IsSerial Name BaseType -------- -------- ---- -------- True True String System.Object So the behaviour outside of python seems to be the same. I have tried to follow the xen source code and I didn't find any special NULL -> "" conversion in the read path but it is quite possible I have missed something. Therefore I believe that SessionExecuteGetValue() of wmi.c should be doing something special so there is compatibility in its behaviour between operating systems.

I don't think this is that good, for the event itself. So, even if the above (Oct 2-3, Berlin), would make things a lot easier for me to attend, I vote for Toronto, as it looks much much more likely that the event would be successful in that case.

Now I'm using 4.1 kernel in test servers but I had occasional problems that I now know exactly was the problem, then for now I use it only for tests. I started to update also few production servers with newer software tested and that seems stable, xen 4.6.0, qemu 2.4, spice 0.12.6 and seabios 1.8.2. I tried to use also new winpv drivers, I installed today latest build on clean windows 10 pro 64 bit domU with same/similar cfg of testing server with same softwares except dom0 kernel (I have 3.2 wheezy from official repo, 3.2.68-1+deb7u5). On boot after winpv install (more exactly the second reboot because the first is working but still with emulated disk and network as already reported time ago) domU's hang at windows boot, full qemu log with trace in attachment. I know since long time ago that winpv require xen>=4.5.0 and upstream qemu>=1.6.1 Probably also backports of these xen patches are needed if xen<4.6 (based on critical problems had long time ago): - x86/hvm: add per-vcpu evtchn upcalls - x86/hvm: extend HVM cpuid leaf with vcpu id I do not understand for sure if kernel>=N is also needed (for dom0) to use winpv drivers or if problem like this are specific to kernel 3.2 (or debian patches). Someone know anything certain about it? If you need more tests/data tell me and I'll post them. Thanks for any reply and sorry for my bad english. --------------040203080100030609090106 Content-Type: text/plain; charset=UTF-8; name="qemu-dm-frc-12.log" Content-Transfer-Encoding: 7bit

Now I'm using 4.1 kernel in test servers but I had occasional problems that I now know exactly was the problem, then for now I use it only for tests. I started to update also few production servers with newer software tested and that seems stable, xen 4.6.0, qemu 2.4, spice 0.12.6 and seabios 1.8.2. I tried to use also new winpv drivers, I installed today latest build on clean windows 10 pro 64 bit domU with same/similar cfg of testing server with same softwares except dom0 kernel (I have 3.2 wheezy from official repo, 3.2.68-1+deb7u5). On boot after winpv install (more exactly the second reboot because the first is working but still with emulated disk and network as already reported time ago) domU's hang at windows boot, full qemu log with trace in attachment. I know since long time ago that winpv require xen>=4.5.0 and upstream qemu>=1.6.1 Probably also backports of these xen patches are needed if xen<4.6 (based on critical problems had long time ago): - x86/hvm: add per-vcpu evtchn upcalls - x86/hvm: extend HVM cpuid leaf with vcpu id I do not understand for sure if kernel>=N is also needed (for dom0) to use winpv drivers or if problem like this are specific to kernel 3.2 (or debian patches). Someone know anything certain about it? If you need more tests/data tell me and I'll post them. Thanks for any reply and sorry for my bad english. --------------040203080100030609090106 Content-Type: text/plain; charset=UTF-8; name="qemu-dm-frc-12.log" Content-Transfer-Encoding: 7bit

with this patch, but that was fixed by: commit 021d1f91ff9c1c10fa59e6d4200628b9d0d37eab Author: Paul Durrant Date: Thu Jul 2 10:23:26 2015 +0100 Fix fall-back to two-level EVTCHN ABI When the EVTCHN code attempts to acquire the FIFO ABI it may fail to do so because the version of Xen may not support it. In this case the code was issuing an EventChannelReset() which has the unfortunate side effect of killing any toolstack-created channels, such as the xenstored channel. This patch moves the existent EvtchnFifoReset function into the base evtchn source module (since it's not ABI specific) and uses that function as the only mechanism of issuing an EventChannelReset() since it contains code to preserve event channel bindings.

In this case the code was issuing an EventChannelReset() which has the unfortunate side effect of killing any toolstack-created channels, such as the xenstored channel. This patch moves the existent EvtchnFifoReset function into the base evtchn source module (since it's not ABI specific) and uses that function as the only mechanism of issuing an EventChannelReset() since it contains code to preserve event channel bindings. (Prior to the move it only preserved the xenstore channel but this patch adds code to preserve the console event channel too, if it exists).

Any news on signed drivers?
Actually the automatic build only with new commit in master branch and keep= only the latest build, is possible to improve it please?
For example I think is good build also latest commit of staging-8.1 branch = and all tags (keeeping all rc and stable build in this case).
This will be easier and faster test also rc builds and any commit for next = stable versions.

No news on XenProject driver signing. There should be some signed Citrix br= anded drivers soon though and these should work on any Xen platform, not ju= st XenServer.

Any news on signed drivers?
Actually the automatic build only with new commit in master branch and keep= only the latest build, is possible to improve it please?
For example I think is good build also latest commit of staging-8.1 branch = and all tags (keeeping all rc and stable build in this case).
This will be easier and faster test also rc builds and any commit for next = stable versions.

No news on XenProject driver signing. There should be some signed Citrix br= anded drivers soon though and these should work on any Xen platform, not ju= st XenServer.

My test Win 10 system with 8.1.0.xx PV drivers just did the first large (non insider) upgrade since GA (build 10240) to build 10586, and I am happy to say, test signing remained honored, and the system upgraded normally.=C2=A0 Very encouraging.=C2=A0 Hats off to the PV dev team.


Few weeks ago I did another tests with latest insider build and it had maintained testsigning setting also on my domUs (I suppose was a windows bug of previous build now fixed), after windows upgrade the pv drivers was not working (used the emulated disks and network instead) but after a windows reboot pv device returned working. I hope that with signed drivers will remain enabled to avoid manual reboot when will be used in production and improving performance during windows upgrade (on low cost notebook was visibly faster than on domUs on server with better hardware, I suppose was for pv disabled during win upgrade)
Same with ovmf instead of seabios except the test with pv disks (without emulated one) where update always fails (tried 4 times total), I don't know if during windows upgrade testsigned drivers are always disabled or is a winpv unexpected case, I'll retry when signed drivers will be available.

I'll keep new winpv drivers tested, thanks to anyone works on them.

Any news on signed drivers=3F
Actually the automatic build only with new commit in master branch and keep only the latest build, is possible to improve it please=3F
For example I think is good build also latest commit of staging-8.1 branch and all tags (keeeping all rc and stable build in this case).
This will be easier and faster test also rc builds and any commit for next stable versions.

No news on XenProject driver signing. There should be some signed Citrix branded drivers soon though and these should work on any Xen platform, not just XenServer.

My test Win 10 system with 8.1.0.xx PV drivers just did the first large (non insider) upgrade since GA (build 10240) to build 10586, and I am happy to say, test signing remained honored, and the system upgraded normally.=C2=A0 Very encouraging.=C2=A0 Hats off to the PV dev team.


Few weeks ago I did another tests with latest insider build and it had maintained testsigning setting also on my domUs (I suppose was a windows bug of previous build now fixed), after windows upgrade the pv drivers was not working (used the emulated disks and network instead) but after a windows reboot pv device returned working. I hope that with signed drivers will remain enabled to avoid manual reboot when will be used in production and improving performance during windows upgrade (on low cost notebook was visibly faster than on domUs on server with better hardware, I suppose was for pv disabled during win upgrade)
Same with ovmf instead of seabios except the test with pv disks (without emulated one) where update always fails (tried 4 times total), I don't know if during windows upgrade testsigned drivers are always disabled or is a winpv unexpected case, I'll retry when signed drivers will be available.

I'll keep new winpv drivers tested, thanks to anyone works on them.

Any news on signed drivers=3F
Actually the automatic build only with new commit in master branch and keep only the latest build, is possible to improve it please=3F
For example I think is good build also latest commit of staging-8.1 branch and all tags (keeeping all rc and stable build in this case).
This will be easier and faster test also rc builds and any commit for next stable versions.

No news on XenProject driver signing. There should be some signed Citrix branded drivers soon though and these should work on any Xen platform, not just XenServer.

This is what I've done so far: - Disabled SELinux - Disabled stub domains (to allow the guest to indirectly connect out to th= e debugger) - Run sockpipe on the debugger system to allow the guest to connect (via a = QEMU emulated COM port) over a local pipe - In the guest: o bcdedit /copy {current} /d "Debugger Enabled" o bcdedit /debug {UUID} on o bcdedit /set {UUID} testsigning on o bcdedit /set {UUID} recoveryenabled off Also tried: o bcdedit /set {UUID} loadoptions DDISABLE_INTEGRITY_CHECK On OpenXT platform, setup QEMU to connect to sockpipe on the debug system: - xec-vm -n win10 set extra-xenvm "serial=3Dtcp:192.168.2.60:7204,nodelay" When I start the guest, QEMU creates the virtual com port and connects to s= ockpipe. Then the Win10 starts in the VM and attempts to connect, but it ju= st halts after Windbg issues a reset (which is normal). I have tested the serial comms.and it works fine. I have also tried Win10 3= 2-bit.did not work. I tried Win7 and Win8 targets .they work fine in the sa= me environment. So my questions; 1. Is there any problem using Windbg (version 10.0.10240.9) with Windows 10= as a target? Did the protocol change and the latest Windbg is not compatib= le? 2. Are there any settings I missed in the bcdedit settings? 3. Any other things to try?

charset=iso-8859-2 Content-Transfer-Encoding: quoted-printable Dear all. I'm using several Windows 10 HVM DOMU-s with XEN4.6. I'm using xen-winpv-devel drivers (latest ones, from November). Previously on the xen-users and on the xen-winpv-development list several users inlcuding me was wishing for signed develoment drivers. Now it seems, that the time has come to tell you, that it is now a blocking condition. Upgrading windows 10 build to the latext 15xxx build automatically turns off testsigning: this cause that upon next reboot during the upgrade procedure, the windows 10 machines fail to start (due to xenbus is not signed). The F8 is offered, I can select "turn off the requirement for digital signature of the drivers", and reboot. Unfortunately the upgrade realizes, that "something did not go well", and immediately starts uninstalling the upgrade package. And I'm stuck here. May I get any response about the signed drivers?

I'm using several Windows 10 HVM DOMU-s with XEN4.6. I'm using xen-winpv-devel drivers (latest ones, from November). Previously on the xen-users and on the xen-winpv-development list several users inlcuding me was wishing for signed develoment drivers. Now it seems, that the time has come to tell you, that it is now a blocking condition. Upgrading windows 10 build to the latext 15xxx build automatically turns off testsigning: this cause that upon next reboot during the upgrade procedure, the windows 10 machines fail to start (due to xenbus is not signed). The F8 is offered, I can select "turn off the requirement for digital signature of the drivers", and reboot. Unfortunately the upgrade realizes, that "something did not go well", and immediately starts uninstalling the upgrade package. And I'm stuck here. May I get any response about the signed drivers?
