Re: [Libvirt-cim] [PATCH] [TEST] New test to verify cdrom media change

# HG changeset patch # User Sharad Mishra <snmishra(a)us.ibm.com&gt; # Date 1293071821 28800 # Node ID d88da81a62f6c4cd6bfc0310f360e4d77863d9f4 # Parent dac5cb514b9a7668b7717ac07bf02b9fcdf3a78d [TEST] New test to verify cdrom media change. Libvirt-cim now allows live cdrom media change. This test checks that functionality.
