<br></div>what I'm going for:<br><br></div>I have (or will have) a set of systems that I only want to run a VMs. I don't want anything but those VMs on the nodes and I don't want the VMs on any other nodes. It's not for GPUs but is similar to the GPU case the instance need the specific resource and I don't want to waste the limite resource on more generic images that don't require it. <br>
<br>I can implement this as either a set of images or flavors. Flavors seem more likely since using host aggregates and instance types it seems pretty clear how to make the flavor(s) run on a given set of nodes, but it's not so clear home (if?) I can prevent other flavors from running on them.<br>
