I'm glad this already came up in this thread as I was just reviewing the 
re-proposal for this spec:


There are other issues in the spec which is why I have a -1 on there, 
but I thought it was going directly against what Matt Booth is talking 
about doing wrt storing the guest xml so that we don't need to rely on 
the nova database when recreating a guest, like on reboot - which is 
exactly what that spec is proposing, just hard-reboot the live migrated 
guest on unrescue.
