I have been able to filter for the domUs via the forward chain taking out

-m physdev  --physdev-in peth0 --physdev-out vif${DOMUID}.0 -j <DOMU chain>

However, I blanked on where to get hold of the traffic to the dom0? Does
that go to FORWARD too? Or does it simply hit INPUT?

Shouldn't that be basic iptables stuff?
If dom0 is not a router, INPUT should be enough. If it's a firewall or
router, packages going through dom0 will be on FORWARD.

As a side note, if you want to prevent iptables managing bridge
traffic altogether you might want to use

net.bridge.bridge-nf-call-arptables=0
net.bridge.bridge-nf-call-ip6tables=0
net.bridge.bridge-nf-call-iptables=0

on /etc/sysctl.conf, and run "sysctl -p" afterwards.
