Should be worth the effort - in my case, I got better throughput with
bridged virtual PV NIC than with PCI passed-thru physical NIC (668
mbit/s against 534 mbit/s!). Shoddy HW (Realtek PCI NICs etc, no IOMMU
on mobo), but the point - PV makes HUGE difference (compared with pure
HVM) so it's worth the hassle. :)
