[libvirt-users] East-west traffic network filter

Hello, I would like to make filter that allows communication only between specified VMs. Those VMs should be specified by their MAC address. The filter should extend clean-traffic but I was not able to get it working with that reference. I have came up with modified clean-traffic which works fine [1]. Is there a way to achieve the same behavior with reference to clean-traffic? Thank you.
