[Libvirt-cim] [PATCHv2 7/7] VSMS: add default console

[Viktor Mihajlovski]

From: Thilo Boehm <tboehm at linux.vnet.ibm.com>

A new function to add a default console has been added. As with
the default graphics and default input device, the default device
generation is optional and depends on the domain type and
architecture.
Initially, we only create an s390 console, which is necessary to
define a runnable guest.
