In my case I had to downgrade iptables *and reboot*. Restarting libvirtd after downgrading wasn't enough! I thought that might be due to an interaction with other firewall rules set through iptables, specifically from ufw. However, the output of "nft list ruleset ip" with ufw started and libvirt's network not started does not change between the 2 versions (aside from packet counts).
