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.

Subject: [ovirt-users] Using 10gb vNIC/vbridge into VM is possible?
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?
Best regards.

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.

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.
