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 Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|
