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.
