I just found very simple solution by adding a dummy interface on host. Same with VMs. So the only hosts with dummy interface are able to run the VMs. Works even with HA-VMs. For sure it is a hack and not so elegant solution, But it works.:) a. *********************************************************** Dr. Arman Khalatyan eScience -SuperComputing Leibniz-Institut für Astrophysik Potsdam (AIP) An der Sternwarte 16, 14482 Potsdam, Germany *********************************************************** On Sun, Nov 30, 2014 at 3:33 PM, Doron Fediuck <dfediuck@redhat.com> wrote:
Just for the record, affinity deals with the relation between VMs, and pinning is about the relation between a VM and a host.
We're considering extending affinity to handle hosts as well, but it's not a trivial change.

Thanks for ideas. I will try http://www.ovirt.org/External_Scheduler_Samples looks nice. Itamar the VM-Affinity selects the VMs, but not the hosts. Would be nice in the next release to add some host pinning options as well. Cheers, Arman.

I am sure you know about vm pinning, but it promise that you can run vm only on one specific vm, in your case you want to run vm on some range of hosts, exclude some specific hosts. At the moment ovirt don't have such thing of policy, but you can write your own filter for scheduler-proxy, that will filter all hosts except ones that you need: http://www.ovirt.org/Features/ oVirt_External_Scheduling_ Proxy http://www.ovirt.org/External_ Scheduler_Samples
You need to install package ovirt-scheduler-proxy and also enable it via engine-config -s ExternalSchedulerEnabled=True. Also additional info you can find under cd /usr/share/doc/ovirt- scheduler-proxy*
why - since 3.4 we have affinity support out of the box? http://www.ovirt.org/Features/ VM-Affinity
I hope it will help you. Thanks

Hello, I have 2 VMs with the negative Affinity. I am looking some way to force the VMs running on different selected hosts. Assuming I have hosts c1-c8: Can I tell VM to run on c1-c8 but not c2 and c4? Thanks, Arman.
