See[1] - do we need to update Lago / Lago OST plugin?

Something like https://github.com/lago-project/lago-ost-plugin/pull/31 perhaps (not tested, don't have the HW).

yes, seems like that should do the trick.

sure, though, that list is also difficult to maintain
e.g. IvyBridge is not an oVirt supported model, there’s no “Skylake” model

Nadav, what’s the exact purpose of that list, and can it be eliminated somehow?

It's to match, as possible, between the host CPU (which is passed to L1) so it'll match oVirt’s.

getting it from "virsh capabilities" on the host would match it a bit better. It would be enough to just make the L1 host report (via fake caps hook if needed) the same model_X in getVdsCapabilities as the L0 

That used to be my initial implementation. I don't recall why it was changed.

It's not that difficult to maintain. We add new CPUs once-twice a year…?

yes, not often
