I have two cluster nodes that have a gigabit network between them for doing live migrations of running kvm VMs. If one of the two hosts go off line, naturally all of the guests then get restarted on the other host. But when the offline host then comes back online, all of the guests that were restarted on the "online" host then try to do a live migration. Given that I only have one gigabit link for doing the transfers, this creates a log jam. The result is that the VMs that timeout then do a "move" or rather shutdown VMs to restart them on the newly online node. For my Linux guests, this is annoying, but with a Windows VM it is a disaster, locking a very impatient dept out of their server for 3-4 minutes. ( One might think that this is a miracle, given that before I set up the cluster a server reboot would take ten minutes. Sigh. )<br>
<br>I would like to make the migrations sequential so that the Windows VM can migrate first, and then the next most important Linux VMs, etc. Is there any way to do this?<br><br>Beekhof suggested that there were several alternatives and that the mailing list would be the best place to ask.<br>
