Does networking work once you are booted into the xen0 kernel before you start xend?

Can you expand on "absolutely no networking"? i.e.:
 - do you see packet RX counts going up over time using ifconfig?
- do packets appear to being transmitted (TX count in ifconfig or tcpdump on the destination machine)?

These sorts of problems are often related to your iptables firewall config.

Some useful data for us would be the output of the following commands:

ifconfig -n
route -n
iptables -L -v -n
iptables -L -v -n -t nat
btctl show
brctl showmacs xen-br0

Brand new to Xen, been going thru the ML and looking at google for an
answer but nothing so far.

brand new install (then yum update of FC4) added, xen and kernel-xen0
packages then reboot.

I start xen (/etc/init.d/xend start) which brings up the bridge. I can see
the device vi ifconfig and brctl show but I get absoluetly no networking.

stop xend service doesn't change anything, change from bridge to routing
doesn't help either.

reboot into the standard fedora kernel and everything is fine.

ethernet card is a dual port 100MB broadcom card using the tg3 kernel

selinux is disabled.

any pointers?
