Title:
n-cpu seems to crash when running with libvirt 1.1.1 from ubuntu cloud
archive
Status in Ubuntu Cloud Archive:
Confirmed
Status in OpenStack Compute (Nova):
Fix Released
Status in “libvirt” package in Ubuntu:
Fix Released
Status in “libvirt” source package in Saucy:
Fix Released
Bug description:
impact
------
any concurrent use of libvirt may lockup libirt
test case
---------
use libvirt concurrently, specifically in nwfilter + createDomain
calls. e.g. run devstack-gate against this
regression potential
--------------------
upstream stable branch update - should be low
We experienced a series of jenkins rejects starting overnight on
Saturday whose root cause is still not quite tracked down yet.
However, they all have a couple of things in common:
1) they are the first attempt to use libvir 1.0.6 from havana cloud archive for ubuntu precise
2) the fails are all related to guests not spawning correctly
3) the n-cpu log just stops about 1/2 way through the tempest log, making my suspect that we did something to either lockup or hard crash n-cpu
After that change went in no devstack/tempest gating project managed
to merge a change.
This needs more investigation, but creating this bug to both reverify
against, as well as track down this issue.
