daily server ISO install fails with a kernel OOPS in KVM

[C de-Avillez]

Binary package hint: qemu-kvm

I started having this after the latest updates to Lucid -- at least both the kernel and qemu.

I actually found it about two days ago while running the automated ISO testing from Soren (https://wiki.ubuntu.com/AutomatedISOTesting). After a reboot on the new kernel (32-15), the autotest would fail continuously, with the same OOPS in the VM.

I have not been able to bypass it, and -- just in case -- will try the previous qemu packages.

[C de-Avillez (hggdh2)]

I have just downgraded qemu* to 0.12.3-0ubuntu3; although it still fails on the 2.6.32-15 kernel, I am able to successfully boot the ISO on 2.6.32-13.

I will try the permutations and zero in the version change that brought it in.

[C de-Avillez (hggdh2)]

Closing Invalid -- today's update to libvirt seems to have done the trick.

Cool, thanks!

[C de-Avillez (hggdh2)]

Sigh. Had it again, after a reboot. Rebooted clean to 2.6.32-15, tried again, failed. Rebooted clean to 2.6.32-13, tried again, worked. So... reopening.

Current status: working on 2.6.32-13, libvirt* at 0.7.5-5ubuntu9, qemu* at 0.12.3-0ubuntu4

I tried to reproduce your kernel oops problem with the lucid alpha 3 server CD, but no kernel oops was given. Can you reproduce the error on a different hardware?

[C de-Avillez (hggdh2)]

No right now, no, but I should be able to next week, when I return to service one of my machines. I do think this is somehow related to my hardware, also.

Hi Carlos-

Thanks for the report. I'm marking this bug a dupe of another one. I think you're absolutely right ... we have a regression in the kvm module in the kernel :-/

[Dustin Kirkland  (kirkland)]

Torsten-

Out of curiousity, when you tried to reproduce this and didn't,
 a) uname -a
 b) cat /proc/cpuinfo

[Torsten Spindler (tspindler)]

It's a 32bit system, maybe that's the key difference?

> a) uname -a
