Hmm, what error did you get from openstack ? The two uses of the
'dom.vcpus' function are both wrapped in try/except so that it is
considered non-fatal if libvirt doesn't provide this.

Are you talking about container based virt here or full machine
based virt ? IIUC Parallels can do both ? With container based
virt, does parallels have the concept of 'vcpus' at all ? We
don't have that in LXC at least.
I don't think it makes sense to support the virDomainGetVCPUs
function if this is only about container virt. I'd be more
inclined to fix openstack so it doesn't fail
