Hi, I've set up a 3 node cluster with all VM KVM virtualized and stored on a raid1 NAS. Everything works fine, migrating VM from one host to another, etc.
The question now is, what happens if a physical node fails? how to migrate all running VM on that node to another living node? I tried to migrate a VM from an stopped node and it says you can't because host is not running. So why should you maintain a cluster if you don't have a simple way to migrate VM on failed node to others? Or maybe an easier to ask question (maybe difficult to answer): what to do with VM when a physical node fails?
I imagine you can achieve this by configuring HA, but I really don't have a reliable network hardware, so I don't think it should be a good idea.
Many thanks in advance, and thanks for the good job!
