Comment 1 Cole Robinson 2014-01-17 22:52:50 UTC

host-passthrough won't ever be explicitly exposed in the virt-manager UI, because libvirt taints the VM in that case. We have a UI button for 'copy host CPU' that is very close to host-model. We don't explicitly allow host-model yet since it has some issues, enumerated here:

https://bugzilla.redhat.com/show_bug.cgi?id=1055002

Upstream now also has UI to allow choosing the default CPU value for all new VMs: it defaults to the nearest host cpu model (similar to vdsm, as a tradeoff between performance and migrate compat), but provides an option for the host-model like behavior suggested above. I think that's sufficient to close this bug
