[libvirt] [PATCH 2/2] Parallels: add connectBaselineCPU().

[Alexander Burluka]

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

Openstack Nova (starting at
icehouse release) requires this function to start VM. Because the
information is taken from host capabilities xml, I've expanded it
and add cpu section in it.
