[ovirt-users] AFFINITY GROUPS
Hi 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?

Re: [Users] Affinity Groups
Yes; Positive affinity makes sure all group members run on the same host. Negative affinity makes sure all group members run on separate hosts. We do have strong/weak attribute which makes this best effort if you wish to avoid failures. - Original Message - From: Maurice James midnightst...@msn.com To: Gilad Chaplik gchap...@redhat.com Cc: users@ovirt.org Sent: Monday, March 31, 2014 7:38:55 PM Subject: Re: [Users] Affinity Groups Shouldnt the negative affinity group keep the two guests apart?
