[ovirt-users] Assign external IP to VM

[Donny Davis]

Are you using built in nics on your hypervisor? If so, then pci passthrough
will likely pass both as they as possibly on the same pci device. At least
that is how my dells work. Honestly you should just be able to put nic two
on its own network untagged and then assign that network to the hypervisor
with the connection. Without SR-IOV support those nics will be dedicated to
that VM.

Just depends on your use case. What is the big picture?
