You might find affinity labels are a better fit in this use case. It would
allow you to add/remove/move hosts in the future much more quickly than hard
coding affinity. But that still leaves the bulk configuration tasks.
The only way to do this quickly is with the REST API or one of the SDKs that
leverage it.
You'd create the affinity labels in the web UI then assign the VMs using the
API.

Hello Nar,
you can achieve this with 2 affinity rules, a positive and
negative one.
In the cluster create the first affinity group VM affinity rule disabled HOST
affinity rule positive set enforcing mode. Then add the VMs and 2 Hosts to
force them to run on these hosts.
In the cluster create the second affinity group VM affinity rule disabled HOST
affinity rule negative set enforcing mode. Then add the rest of the VMs and the
2 Hosts to force them not to run on these hosts.

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
