Yes, that is correct.

Ah, I see.
Is there a way to get an external network interface (that happens to be
a target of an external switch's port mirror/monitor session) to pass
through to a VM? A way that still allows for live migration would be
best of course, but even without that would be a start.
We plan to support passthrough natively in ovirt-3.6.
Until then, you need to do this yourself, with the help of vdsm hooks.
