OpenStack Nova requires this function
to start VM instance. Cpumask info is obtained via prlctl utility.
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.
Unlike KVM, Parallels Cloud Server is unable to set cpu affinity
mask for every VCpu. Mask is unique for all VCpu. You can set it
using 'prlctl set <vm_id|vm_name> --cpumask <{n[,n,n1-n2]|all}>'
command. For example, 'prlctl set SomeDomain --cpumask 0,1,5-7'
would set this mask to yy---yyy.
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
