Would also be very cool if the framework had pre-migration hooks. For example, allow someone to write a plugin to verify that the target host is qualified and in a good state to accept a migration before it actually starts. Also, some physical devices may need to be configured/re-configured on the target prior to a migration (infiniband, fiber channel, iscsi) and it would be good to have plugins for that as well. Mike
