I have tested qcow2,

seem to works fine now, snap/rollback with or without vmstate.



rbd : snapshot works fine, with vmstate too.

but rollback with vmstate , give timeout after rollback when vm is starting. 
Maybe loadvm doesn't work, I don't know if the vmstate is correctly save or not. 
rbd block driver don't support savevm/loadvm, but I don't know how it's works with yours patchs.


I'll test sheepdog tommorow. (last sheepdog git seem to have stability problems)
