Hi all, I'm trying to wrap my head around whether it's possible with the existing scheduler filters, to put a limit per host on the number of instances per instance-type/flavor? I don't think this is possible with the existing filters or weights, but it seems like a fairly common requirement.
The issue I'm thinking of using this for is that of instance-to-host fragmentation in homogenous deployments, where there is a tendency as the zone approaches capacity to hit a utilisation ceiling - there are rarely any "gaps" large enough for high vcpu count instances. I'm guessing that limiting the number of smaller instances per host would help to alleviate this. Looks like knocking up such a filter wouldn't be too hard, just want to check whether there is another way...? -- Cheers, ~Blairo
