ovm guest vms reboots automatically

kkw-ceylonApr 4 2017 — edited Apr 4 2017


I wanted to change ocfs cluster heartbeat parameter in ovm x86 cluster. In order to do that I need to shutdown all guest vms in the nodes and change the parameter in all the cluster nodes.

Eventhough I have set the inbound migration lock in all nodes, guest vms which I have already shutdown started to migrate to a single node ( only that ) .

I have tried to stop the guest vms gracefully and forcefully using xm commands. But some shutdown guest vms automatically started out of nowhere.

Have any one experienced such scenario.

What is the best practice in shutting down all vms in a HA cluster.
