Re: [Xen-users] Live Migrating a VM while it is paused



If it gets pause anyways (which was maybe your concern?) Perhaps you don't need 
the additional step? Just a thought. M

I believe that during the process of migration (the step when the actual
move takes place) the domU gets paused anyway. It certainly shouldn't
hurt anything. I don't know whether it gets auto-resumed or of the pause
state is preserved, but that's easy enough to test.
