If I understand you correctly you are trying to replace the physical device mirroring with VM?
Yes, that is correct.
If this is the case I don't think it's possible to do it with port mirroring oVIRT feature. The existing oVIRT port mirroing feature is for mirroring traffic between VM devices for specific Network. So if you have 3 VMs with network <X> you can monitor on 1 VM that specific network that is used between 2 other VMs.
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. http://libvirt.org/formatdomain.html#elementsNICS
