I have 3 hosts that have a couple 10GBe interfaces on em. I am having an issue getting a VLAN on a KVM host to run at full 10GBe. It's running at 1GBe from my tests but only on VLAN 8. If I assign the VM IP to be the same subnet as the HOST IP subnet it gets full 10GBe. So I am not sure what I am missing. The VLANs can pass through fine, as DHCP gets the right IP on the VM when it's tagged, it's the speed that is throwing me off. Why can't VLAN 8 get full 10GBe? Do I need another bridge for just this VLAN on the host?
