Is your dom0 ip address on xenbr0 or eth0?
Looks like you have libvirtd running (possibly on RHEL/Centos), in
which case the IP will be on eth0. If that's the case try changing the
rule to

/sbin/iptables -t nat -A PREROUTING  -p tcp -i eth0 -d dom0_ip_address
--dport 3389 -j DNAT  --to 192.168.122.77:3389

and if your default rule is reject you need to add an ACCEPT rule on
FORWARD chain as well.

Regards,

Fajar
