Hi,<br><br>Can someone tell me whether setting positive and negative VM affinity rules will be at all possible with oVirt at some point in time, i.e. is this on the roadmap?<br><br>I need to be able to tell VM&#39;s to run on different hosts, spread them around, so to speak. For example, domain controllers would be better off running on as many different hypervisors as possible, the way I see it. That way, the failure of a single hypervisor has minimal impact on the infrastructure. I know there is a feature to pin VM&#39;s to a single hypervisor, but that&#39;s not quite the same. I would like to group the domain controllers and then tell them not to run on the same host as other members of that group as much as possible.<br>
<br>The other way around would be nice as well: have several VM&#39;s run on the same hardware. For example, a three tiered web application would probably perform better if the VM&#39;s are all on the same hypervisor. I know I could pin them all to the same hypervisor, but still: that&#39;s not quite the same. I want to be able to group the web app VM&#39;s and tell them to try to run on the same hypervisors as the other members of the group, so they can move to another hypervisor as a group if the need arises.<br>
<br>Apologies if this has been asked before or documented in some place I haven&#39;t looked yet.<br><br>Regards,<br><br clear="all">Maxim Burgerhout<a href="mailto:maxim@wzzrd.com" target="_blank"></a><br><br><br><br>
