Re: [ovirt-users] Using 10gb vNIC/vbridge into VM is possible?
Dear Amador. No, unfortunately not. This was just a friend question, because he need VM with 10GB NIC's. Today he is using Xenserver, this solution does not attend his expedition and he is research another solution. I told him about oVirt/KVM but this is a prerequisite to use. I will plan with him to try make a project to test a take the resolts. Best regards. On Fri, Dec 19, 2014 at 1:18 AM, Amador Segundo <asegundo@redhat.com> wrote:

Hello all.
Today a follow work ask me if is possible to use vNIC or vbridge in a VM managed by ovirt.
What he wants is to have a virtual 10gb network to some machines.
All hosts NIC's are 10gb.
Is this possible?
If yes how can I do it?

Maybe we should report vNIC speed as the speed of underlying NIC/Bond. Even being the underlying NIC/Bond shared, it would reflect better the vNIC max. speed than a fake hard coded value.

Or maybe even have it configurable from the GUI?...

I tried a quick iperf test a while back and got 3-4Gb/sec between a pair of VMs on separate hosts with a 10G infrastructure, no real tuning and no SRIOV. That met my needs so I didn’t try anything further. If you were aiming for 10G for all, you’d want to work on SRIOV I imagine, but they get pretty good performance even without it.
Maybe we should report vNIC speed as the speed of underlying NIC/Bond. Even being the underlying NIC/Bond shared, it would reflect better the vNIC max. speed than a fake hard coded value.
Or maybe even have it configurable from the GUI?...
... or maybe hide the "speed" as deep as possible, as it is one big lie. It's a lie when discussing physical nics (where speed is affected by host load or switch buffers) and it is certainly a lie when it comes to vNICs, with over-commitment of bandwidth.
