Without shared storage, I personally don't see much of a point. This strikes me as a "move" tool, more than a "migrate" tool. It's value is certainly very high, and I could see it being an excellent way to move a VM from one cluster (and it's shared storage) to another. That said, without some way to keep the VM in sync, I can see very few use cases that would make this useful to HA. digimer -- Digimer Papers and Projects: https://alteeve.ca/w/ What if the cure for cancer is trapped in the mind of a person without access to education? _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
