[Libvirt-cim] [PATCH 2 of 3] [TEST] #2 Add vsms_util.py

# HG changeset patch # User Kaitlin Rupert <karupert(a)us.ibm.com&gt; # Date 1213147576 25200 # Node ID 1ea2eaa7349fb3c16281c4071b252104c7fde5c2 # Parent 94274683dee5aed5621dc555c8604dc56b378c85 [TEST] #2 Add vsms_util.py This module is for vsms related utility functions (for AddResource, ModifyResource, etc). Add the mod_<> functions. These are identical the code paths in VSMS 08_modifyresource.py except for mod_net_res(). mod_net_res() - In the case of Xen, the bridge name needs to be verified. This is because the network interface type is converted to a bridge interface by libvirt.
