bridge + SR-IOV guests with KVM

Hi, I managed to get SR-IOV with an Intel I350 NIC to work.For this I followed the documentation on this page: https://wiki.libvirt.org/page/Networking#Assignment_from_a_pool_of_SRIOV_... But as I have more VMs then VF on the NIC I also have a bridge wich serves the other guests. As I run Debian Buster as host I followed the documentation here: https://wiki.libvirt.org/page/Networking#Debian.2FUbuntu_Bridging If I use only the SRIOV everything works as expected. All guests can be reached for the network and the guests and host can reach each other. The same goes for a sole bridged environment. As I dived into the issue I found an answer form the intel community: https://community.intel.com/t5/Ethernet-Products/82599-VF-to-Linux-host-b... It says I need to add the "VF mac addresses and eth0 mac address to bridge forwarding database". I have done this with the following command: bridge fdb add 52:54:00:3c:1c:e6 dev eth_lan0 The mac address is from my VM which is on the bridge. And the eth_lan0 interface is the physical interface of my bridge and also the PF of my I350 NIC. This seems to work. But doing this manually is annoying and a bit of a hassle when creating new VMs on the bridge. I there a way to let libvirt do this work?
