I noticed several attempts to address the issue with KVM HA in Jira and Dev ML. As we all know, there are many ways to solve the same problem, on our side, we've given it some thought as well - and its on our to do list.
Specifically a mail thread "KVM HA is broken, let's fix it" JIRA: https://issues.apache.org/jira/browse/CLOUDSTACK-8943 JIRA: https://issues.apache.org/jira/browse/CLOUDSTACK-8643 We propose the following solution that in our understanding should cover all use cases and provide a fencing mechanism. NOTE: Proposed IPMI fencing, is just a script. If you are using HP hardware with ILO, it could be an ILO executable with specific parameters. In theory - this can be *any* action script not just IPMI. Please take few minutes to read this through, to avoid duplicate efforts...
