# User Dan Smith <danms at us.ibm.com>
# Date 1224018018 25200
# Node ID 9e4f5b57f4125904121d650cc03866b6fbf45084
# Parent b9a93806b73aaaccef8ade2cc43170e77fe01755
Add KVM_CDROMDrive class
This patch makes the Device provider return a KVM_CDROMDrive class where
appropriate. All the associations that mention LogicalDisk have been updated,
but it would be good to ensure that the test suite is properly checking the
links, despite the classnames of the devices.
