I do come across occasional bugs where people were using mixed
environments with Compute nodes on RHEL6. But that doesn't mean,
OpenStack Gate should continue to use ancient versions.

It'd be helpful to see this change (increasing the min libvirt version)
in Gate, not least because it saves time spent on debugging issues that
were fixed in newer libvirt releases.

Speaking of versions, libvirt 1.2.2 was released on 02-MAR-2014 and QEMU
1.3.0 was released on 03-DEC-2012 -- both sound more than reasonable,
FWIW.

Maybe QEMU min version can be bumped too?
