<div>You can set attributes on flavors that must match the attributes on hosts or the host aggregates. So you can basically always make sure a specific flavors goes to a specific compute node or type (like disks=ssd or class=gpu). Look at nova flavor extra_specs
documentation and the aggregate_Instance<span style="font-style: italic;">_</span>extra_specs under the scheduler options.</div>

<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">you usually do that on an instance level with server groups. do you have an example where you might want to do it at the flavor level?<br>
<br>
Thanks,<br>

<div dir="ltr">I'm sure this is possible but I'm trying to find the info I need in the docs so I figured I'd pitch this to you guys while I continue looking:
<div><br>
</div>
<div>Is it possible to set an affinity/anti-affinity policy to ensure instance Type A is weighted for/against co-location on the same physical host with instance Type B?
<div><br>
</div>
<div>Basically I have no requirement for server-group affinity but rather to ensure specific workloads are as separate as possible.</div>
<div><br>
</div>
<div>Thoughts?</div>
