I'm seeing this as well. Some information that may help. I found the problem with 5.4.0-137. I found that when looking at tcpdump on the guest and the bridge I can see ARP requests on both interfaces. On the guest I can see it responding to the ARP request, however I don't see the ARP response on the bridge interface.
