I have something cooking here using the latest version of Pacemaker; should this turn out to work, it would make many things a lot easier. I'll elaborate a little bit more on this once I have it working the way I want it. Concerning the general subject of virtual machines (and clustered VMs for that matter) within OpenStack, I think there is some stuff missing in Nova that would be necessary (granted -- in one way or another, it would be possible to make Pacemaker deal with VMs that have failed within Nova, but in my eyes, that'd be crazy). Nova knows what VMs are supposed to be there and Nova can find out which VMs are in fact running and which are not, so I think Nova should make sure that those VMs that are supposed to run are, well, running :) Best regards Martin -- Martin Gerhard Loschwitz Chief Brand Officer, Principal Consultant hastexo Professional Services CONFIDENTIALITY NOTICE: This e-mail and/or the accompanying documents are privileged and confidential under applicable law.
