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

[Nick Katsipoulakis <popanik@xxxxxxxxx>]

Actually, I want to pause it in order to block IO calls from getting written to the disk. That is why I asked.

But I noticed that if my VM is paused, Xen won't let me migrate it. Is this behaviour by default, that paused VMs are not migrated?

Thanks,

Nick

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.
