Maybe the host is blocking traffic from the guest interface
with iptables? I used to add -i eth0 on every iptables rule
before trying kvm. If that's the case, you should remove
them or replace eth0 by br0.

On the other side, sniffing traffic on the host side should
help determining at least if packets arrive from the guest.
You can use tcpdump, wireshark, etc.
