In the end I enabled global maintenance mode, stopped hosted-engine on my HE VM, then changed the cluster and CPU profile (I think?) from within the database, and started it back up again. That then permitted me to remove the old cluster using the UI. I did several tests stopping and starting the engine and the VM comes up fine, so I believe that was enough to make the change, it's just rather nasty.

It seems I have to create a new cluster, migrate a host over, migrate a few VMs, and so on until everything is moved over. This really isn't ideal as the VMs have to be shut down and reconfigured, but doable. What I seem to be stuck on is changing the cluster on the HostedEngine. I actually have it running on a host in the new cluster, but it still appears in the old cluster on the web interface with no way to change this. Any hints, please? This is on oVirt 4.1.9. Upgrading to 4.2.1 is not out of the question if it's likely to help. Thanks, Chris -- Chris Boot bo...@boo.tc ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
