Comment 5 for bug 1673467

Hi,
I was able to reproduce at least partially.

I must admit that I never heard about host-model before, host-passthrough usually.
Checking the doc [1] reveals that the function is broken pre libvirt 3.2/qemu2.9 - and e.g. the qemu is not even released yet.

So even if we would make host-model pass here on the initial check it will not "do what it is supposed".

OTOH the more common host-passthrough is working - so much I could confirm.

I see why host-model is nicer than passthrough, as it would be a bit more portable.
Maybe openstack changed and on Xenial/Mitaka selected passthrough - we might want to do so again on Ocata.

@Openstack Team
1. could you check what model was passed on Mitaka/Newton, I'd assume host-passthrough but well that is only "assuming"
2. if #1 is true, what would you think about fixing this by going back to host-passthrough for Ocata on aarch64?
