David: Indeed ! How stupid I am. I missed the root cause inside QUEMU log file. This was clear enough... error: kvm run failed Device or resource busy This is probably because your SMT is enabled. So I switch SMT (Power Simultaneous Multi-Threading) off and now it's OK; VMs are running and installing. It had been years since I last touched KVM on Power and I lost my reflexes. So please forget my precedent comment telling I had the same issue on Power platform. It was similar symptoms but not the same problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866870 Title: KVM Guest pauses after upgrade to Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1866870/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Andreas, so the only upgrade you did to trigger this for you was to bump the kernel from 5.4.0-28.33 to 5.4.0-29.34 - nothing else? I have not (yet?) heard other similar reports, but it might be just too early? At least on my system for now things still work with the new kernel like before. I'd recommend filing a new bug, refer to this one as maybe being related and adding the following right away: - kernel version (you have this here I know) - qemu/libvirt/seabios/ovmf version (if you don't mind just attach `dpkg -l`) - guest XML (if using libvirt) otherwise the qemu command-line - add a cross check and report what happens with other guests configs (e.g. non windows, using another bios as the former issue was tied to seabios, use different guest CPU types) - the full /var/log/apt/history.log - a date when you last started the VM successfully (not just still-had-it-running, but started it) and the date when it started to fail (probably yesterday then I guess) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866870 Title: KVM Guest pauses after upgrade to Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1866870/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1866870] Re: KVM Guest pauses after upgrade to Ubuntu 20.04
Thanks David! While bisecting on upstream git with just "-cpu Penryn" we have seen that it always works there. So it might be an interaction with some Ubuntu build/packaging/configure detail together with these old chips. While we still can't be sure if the VMX warnings are a red-herring chances are that only "-cpu Penryn,vmx=on" will trigger the issue - Andreas will test and bisect with that once he is back online - we will see if that is any different. I'll also build a Ubuntu'esque 4.2 with the Penryn changes of [1] reverted just to complete the interim picture of our testing. That is available for testing at [2]. Further I added a Ubuntu build with rather crude reverts of almost all VMX related 4.2 changes.

Andreas was so kind to try kenels 4.4, 4.15 and 5.6 all fail (with qemu 4.2) He then tried Eoan (qemu 4.0) and Focal (qemu 4.2). 4.0 worked and 4.2 failed.

The vmx things make me wonder about a fix Paolo did a while ago for enabling inidivudal vmx features rather than vmx as a whole; but I can't remember if that was a kernel or qemu fix. One thing I notice, that may be a red-herring, all of the machine code in the errors are 'f3 0f 1e fb' which is the new 'endbr32' security instruction - but that's really a rep nop, that I thought old instructions can handle anyway?? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866870 Title: KVM Guest pauses after upgrade to Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1866870/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Yeah @Boris - it really seems to be an issue bound to the Merom/Penryn processor generation. I asked Andreas to check through some kernels and qemu versions so that we maybe eventually can consider bisecting something. But that will take a bit of time. Of course everyone able to spend some time can consider checking a few kernels of [1] as well (probably the easiest test to begin with).

[Bug 1866870] Re: KVM Guest pauses after upgrade to Ubuntu 20.04
It detects host as Penryn as well for @tstrike. Which is fine if it is a chip of around that era. He reported to have an "Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz" And for that chip the detection and chip used might be correct. So to summarize all repro fails, but on Penryn ERA chips 2/2 cases trigger the bug. I wonder if one that wants to reproduce needs a system with such a chip as well then to test and trigger this. There should be plenty of people on CC as this is mirrored to qemu-devel due to the upstream qemu task. Is there an microarchitectural x86 specialist that knows if the chips of that generation have some special issues in regard to VMX that might explain what we see here? It would be great if everyone could ask around for more systems with chips of that era. Maybe we can further bisect which work and which will fail. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866870 Title: KVM Guest pauses after upgrade to Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1866870/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1866870] Re: KVM Guest pauses after upgrade to Ubuntu 20.04
@Boris - in your log I've seen that you also got the Penryn cpu which I find
odd.
"-cpu
Penryn,vme=on,vmx=on,x2apic=on,tsc-deadline=on,xsave=on,hypervisor=on,arat=on,tsc-adjust=on,arch-capabilities=on,skip-l1dfl-vmentry=on
\"
Assuming you also only used default I wonder how it got to that, maybe the
reason for that is the same reason that eventually triggers the error.
But virt-manager/libvirt would usually just do a best-fit (for me
Haswell-noTSX-IBRS).
@Boris and @tstrike Could you both please report:
$ virsh capabilities
$ virsh domcapabilities
$ sudo qemu-system-x86_64 --enable-kvm --nographic --nodefaults -S -qmp-pretty
stdio
{"execute":"qmp_capabilities"}
{"execute":"query-cpu-definitions"}
Note: the command seems to hang as you are on QMP, then just enter the two
commands below one by one. This will add "qemu's explanation why a given cpu is
usable or not"

[Bug 1866870] Re: KVM Guest pauses after upgrade to Ubuntu 20.04
I tried with a guest XML matching yours (other than disk setup). I didn't get those errors you reported even when using your config. Notable differences to my default - your guest has: - a rather old chip type (Penryn is a 2007 chip) - a rather old machine type (uses xenial which matches ~pc-i440fx-2.5) This probably based on when the system was created. But since you also have the same issues on the windows guest which has the modern: hvm So this isn't a route we need to go down... Note: I tried this on kernel 5.4.0-14-generic with some common not too old & not too new chips - Intel(R) Xeon(R) CPU E5-2620 - AMD Opteron(tm) Processor 4226 Then I remembered that you followed to disable nesting and after all vmx-* you see in the warnings could be related. I ran this and restarted my guests: # sudo rmmod kvm_intel # sudo modprobe kvm_intel nested=0 or # sudo rmmod kvm_amd # sudo modprobe kvm_amd nested=0 Even then I didn't get the same warnings or crashes you got.

Give me about 3 hours and I will update the report with the items requested. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866870 Title: KVM Guest pauses after upgrade to Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1866870/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1866870] Re: KVM Guest pauses after upgrade to Ubuntu 20.04
@tstrike - can you trigger the same issue with all your guests? You list Windows and Centos guests, does it triggers with Centos as well or only the Windows guests? Also if you have a chance (just to be sure) does it trigger with an Ubuntu guest as well? This would help for people retrying not using a case that doesn't even trigger in your setup. @tstrike - you seem to hit this while starting your guest through libvirt. Could you please attach your guest XML so that we can try to recreate this case? $ virsh dumpxml That will help when trying to recreate your case. @tstrike It would also be helpful to get your qemu commandline as well as any further messages qemu might have reported. You'll find that in the per guest log file at: $ cat /var/log/libvirt/qemu/.log If you could report all that here that should be useful for everyone tracking this bug. ** Changed in: qemu (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866870 Title: KVM Guest pauses after upgrade to Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1866870/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@tstrike: finally for the sake of apparmor denials or any other odd error that might be mentioned in there attaching the output of `dmesg` on your host might be useful as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866870 Title: KVM Guest pauses after upgrade to Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1866870/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

As outlined here:
https://bugs.launchpad.net/qemu/+bug/1813165/comments/15
After upgrade, all KVM guests are in a default pause state. Even after
forcing them off via virsh, and restarting them the guests are paused.
These Guests are not nested.
A lot of diganostic information are outlined in the previous bug report
link provided. The solution mentioned in previous report had been
allegedly integrated into the downstream updates.
