I skimmed that but it didn't tell me much.  I'll read it in detail...

xenbr0          8000.feffffffffff       no              vif3.0

I tried manually adding eth0 on dom0 to the bridge, and that just
broke the networking completely.

Unchanged from default:
  (network-script network-bridge)
  (vif-script vif-bridge)

Just like that - unchanged from default.

I only have dom0 and one domU.  dom0 and domU canot ping each other.

Distro is Centos 4.4.

I downloaded the RPMs from xensource.org.

On dom0:
# rpm -qa | fgrep xen
kernel-xen-2.6.16.33-3.0.4.1
xen-3.0.4.1-1
