[CentOS] Question - Xen host, DHCPD and guest VMs

I have a question about a Xen host that runs dhcpd and installing 
guest/running guest VMs (that use DHCP)...

On other hosts or hosts running VMs, they are absolutely able to get DHCP 
addresses no trouble...  However, the fun begins when the machine I run 
dhcpd on is also hosting VMs.  I can see in /var/log/messages the request 
and ack from dhcpd but the guest VM never hears it.  If I should bounce 
dhcpd prior to a guest install or start a guest VM - everything works just 
fine.

I'm guessing, perhaps, there is some iptables rule I need to set up? 
Based on the init scripts, dhcpd definitely starts before xend and 
xendomains and ultimately the xen bridge...

Anybody know what I need to do :)  I've been bouncing dhcpd in 
/etc/rc.local and starting any VMs there.  Although annoying, I'd rather 
do it "right" so I can auto start my Xen guests...

Thanks ahead of time!
