[ovirt-users] How do I start an VM in a different 3.6 cluster

Thu Mar 17 21:11:10 UTC 2016

I re-ran the Reports server engine-setup again and the second cluster appeared after that in the reports interface.

The second cluster has 4 hosts and about 30 VMs running fine. It is a different CPU architecture than the Default cluster (Sandy Bridge vs Nehalam) though.

Just to elaborate: If a VM is created in either cluster, the only option in the cluster pulldown is the cluster it was created in.

So there is no option on which cluster to run a VM in. It can only be migrated to another cluster while it is running.

The reports will only show clusters with hosts\vms. Depends on what the report is about.

There is definitely something amiss with my 2 clusters.
I set up the Reports engine before adding the second cluster. The reports engine does not show any of the second cluster hosts.

All Cluster pull down menus in the Reports only show the first cluster.

Sounds logical, that is what I thought.
Except my VM's only have one cluster to choose from, even though there are 2 clusters with running machines in both.
I have no idea how to tell if a cluster is 'UP' they certainly work fine in themselves.

If you click edit on the VM, the top right will have a drop down, where you
can select the cluster to run the VM in. The target cluster must be UP for
this to be an option in the drop down. Example here [1]
