AFAICT there's no x86_64 (or ppc64, or s390x, or ...) machine type that can use CPU clusters.
I believe x86 should be gaining CPU cluster support in QEMU, though the current patch is suggesting to call them 'modules' when configuring the guest, just to absolutely maximise confusion when linux calls them 'clusters'.
Lovely. Any chance we're still in time to prevent that specific trainwreck from happening?
I'm trying to discourage it, though their latest reply actually indicates they want to report 'clusters' and 'modules' as distinct concepts, so we've got even more to do on libvirt side :-)

It doesn't sound quite as bad then. Better than overloading an existing term with new meaning, that's for sure. The whole CPU topology hierarchy has gotten way beyond silly a long time ago anyway :) -- Andrea Bolognani / Red Hat / Virtualization
