1G or 10G ports to the virtual machines when SR-IOV is enabled for 10G ports in the
This issue occurs due to limitations of the virtual Ethernet bridge. All transmitted
broadcast packets are looped back by the controller. This affects the functionality of the

performance. If you have only two interfaces on this bridge (one NIC interface and
virbr0-nic), there is no performance impact.
b) Another option may be to use the MacVTap interface to the guest instead of the

I hope this can be a great help to address this concern soon : )
Have a good one!
