Interestingly, lwp is not there (not sure if it'd still show up anyway, though). In any case, the fact that it was there only for some CPUs: - could be (part of) the cause of the issue, although I don't think we can be 100% sure - looks like a bug to me (but I'd have to re-check the specs) In any case^2, using the output of this command as the <cpu> of the VMs is, IMO, definitely the best way forward.
