OpenStack Nova requires this function
to start VM instance. Cpumask info is obtained via prlctl utility.
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.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
