Could someone please test the package currently in saucy-proposed?
If it's not tested soon, it will be superseded by a security update...

Unfortunately the upstream libvirt patches contained a flaw, and
required an additional patch to fix the issue
https://www.redhat.com/archives/libvir-list/2014-March/msg00501.html
https://bugzilla.redhat.com/show_bug.cgi?id=1066801
The issue only appears when you have on the order of 20+ VMs
Thanks, Daniel! I'm pushing a new proposed package with that additional
patch.

available at

Please help us by testing this new package. See

@berrange,
I've recreated the problem with server side logging enabled. please see
libvirtd.txt.gz at the following url:
http://logs.openstack.org/64/67564/6/check/check-tempest-dsvm-
full/dd0e0de/logs/
The screen-n-cpu.txt.gz has the client-side logs as usual.

Thanks, that confirms my earlier guess. I've managed to reproduce the
scenario locally in a way that openstack would definitely hit. Basically
concurrent use of virDomainCreate and virNWFilter{Define,Undefine} is
racey and unsafe as it stands. I'm working on a fix.
