I would like to know how AFFINITY GROUPS works.

I have 2 VM in 2 hosts, each VM runs in a host. Let's call

HOST_X where vm01 runs

HOST_Y where vm02 runs

I have set up an affinity group where it says vm01 relates to HOST_X, vm02 relates to HOST_Y. VM affinity rule is set to negative and HOST affinity rule set to positive. I need both vm01 and vm02 to run in their respective physical host.

I have a problem, when vm01 is stopped and HOST_Y is rebooted vm02 starts in HOST_X, how can I avoid that?

Thank you

Luis Sanchez
