This seems to be a popular topic of late, I think we had a similar question just last week.
You can't assign a VF to a bridge. By definition a bridge required the devices attached to it to be in promiscuous mode. A VF on the other hand sorts traffic based upon L2 filtering and cannot be placed into promiscuous mode, and therefore can't be used as a bridge.
Hope this helps.
Thanks for the quick reply. I really appreciate it!!
So there is no way to make a VM with 2 SRIOV VF interfaces act as a bridge?
It works perfectly with Vswitches, but I really need the performance that SRIOV offers.
If there is a way that you can think of then I will try anything experimental etc.
I really need a VM running under KVM with high performance SRIOV bridged NIC's.
Looking to get as close to 10Gbps line speed as possible here
