Hi oVirt land

Hope you are well. Don't even know what to call this. But let me describe what I want to achieve.

We have a cluster with say 100 vm's. But we want two use two hosts in the cluster two run only certain VM's. I think you can do that with affinity rules. But how can I restrict those two hosts to only run the VM's, meaning that no other VM's will run on them.

I don't want to go and edit the 100 other VM's to not run on 2 hosts. Is there an easy way for doing this?

Oracle VM uses pools, I dont know what vmware uses.

Any advice will help.

Regards

Nar
