[Libvirt-cim] [PATCH] Add support for console/serial grahpics devices

Tuesday, 5 April 2011

# HG changeset patch
# User Chip Vincent <cvincent(a)us.ibm.com&gt;
# Date 1301520765 14400
# Node ID 18793660dbc8f0755062a7f90902379288501f4c
# Parent  a521a11eeec4b41399ca954ab17b874a708eb4b3
Add support for console/serial grahpics devices

Add support for Graphics RASD ResourceSubType = console | serial. This includes support
for
allowing more than a single graphics RASD instance. Instances can be created externally
or
during DefineSystem. No changes to current level of hotswapping.
