Sean (cc'd) might have some information on what he's doing in the OVS w/ 
DPDK build environment, which AFAIK requires a later build of libvirt 
than available in most distros.

A generic "build libvirt or OVS from this source repo" dsvm job would be 
great I think. That would allow overrides in ENV variables to point the 
job to a URI for grabbing sources of OVS (DPDK OVS, mainline OVS) or 
libvirt that would be built into the target nodepool images.

Thoughts?
