Description

This ticket is to match the CPU parameter with the new cputune attributes of libvirt. Xen drivers update the ticket-based scheduler to distribute physical cpu cycles among VMs (So VMs with higher CPU values will get more physical CPU). This new feature will level the KVM driver with the Xen one in this area.

Also we may include CPU-pin attributes. The Xen driver could implement this trough the hwloc utility
