n-cpu seems to crash when running with libvirt 1.0.6 from ubuntu cloud
Note that we inadvertently tested libvirt from UCA on all our CI
infrastructure today and ran into bug 1266711 (probably related).

I don't think I've managed to reproduce this. I do get errors, but they
seem to be VMS failing to start which is more likely due to other
reasons. I tried to reproduce with the instructions in comment #7, and
expected to get libvirt hung to the point that the script in comment #6
would hang.
I got a few minutes to recreate the failing test run and tarred up the
screen-n-*.log files (attached) once it finished.

Anything in the nova-compute logs when this happens?

Probably--I wasn't collecting logs, just confirming whether or not
gating is going to break if we reenable UCA. If nobody with nova
debugging experience or interest in using UCA/newer libvirt has time to
repeat that experiment, I can recreate it and find/attach the service

Daniel Berrange is proposing that nova stop supporting libvirt older
than 0.9.11 as libvirt should be able to provide pip installable python
bindings for libvirt = 0.9.11. The vast majority of our test slaves run
on precise which has libvirt 0.9.8 in the base install. The only sane
way for us to
Please can this be retested using the 1.1.1 version we now have in
cloud-archive for Havana.
Thanks.

I managed to reproduce it by using a smaller disk for my devstack VM.
The backtrace of libvirtd is attached.

Today, I created a new Ubuntu 12.04 VM with larger disk(20G).
After tempest created and deleted 641 instances, it failed to reproduce the

yesterday .

Title:
I can't reproduce this by only installing qemu-kvm and libvirt-bin on
precise with the cloud-archive. So it appears to be something which is
exacerbated by configuration changes done by devstack.
Can you reproduce this on saucy (which has libvirt 1.1.1)?
