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. 

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