I still cannot belive this.
This is test under bonding (round-robind) and bridging (bond0 -> br0 to
expose VM to LAN)
From VM Debian with one Virtio NIC to Debian Hypervisor I have (1, 2
and 3 connections at once):

And this is just AMD Phenom II X2 550 @ 3.1 GHz. Xeon's probably can do
much more...
Where is the trick to get raw 2Gbits/sec from LAN to VM?
Maybe direct attach NICs to VM and then bond them?

Tom
