Yaniv,

So are you telling me that the virtual machine will get 10Gbit speeds even though it only reports 1Gbit? 

Yes, theoretically. The historical reason is that when it was developed, there was a need to display some link speed (ethtool, Windows device manager) and back then 1g seemed like high speed. 

Getting really 10g is a challenge, but I have seen 7-8g on a bright day.

We are running oVIRT 3.5, until one of vendors supports us moving to 4.0. Our RHV hosts have 20GB aggregated NICs on the box, however our VM's I notice only have 1GB NICs available. I do see that the Virtual machine is using the "virtio-net-pci" device, is there a way to get this Virtual Machine to have a 10GB NIC? When i run 'atop' on the RHV host I notice that it claims the virtual NIC is hitting 100% utilization at times. 

Disregard that number. It's a virtual NIC, and so is the 1g number.

What methods do I have available to increase the 1GB NIC to something higher hopefully to 10GB ?
