[libvirt] [PATCH 3/3] Parallels: Include CPU info in the capabilities XML

[Alexander Burluka]

From: A.Burluka <aburluka at parallels.com>

Openstack uses (or will start to using) CPU info from the
capabilities XML. So this section is expanded, added CPU info
about arch, type and info about number of cores, sockets and threads.
