This can be implemented by the management application without problems, although it's much easier inside kvm. > Easier, yes. But then once it is done, people wanting a different behaviour for some valid reason are stuck with that. This is the very reason we expose information about migration in the monitor to begin with. Again, I believe the fix for this convergence problem does not belong here. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
