I had the same problem with my DomU networking - I could ping my nameserver, but not get names.  I fixed it using the oft-quoted:

ethtook -K eth0 tx off

to turn off checksumming.  Apparently that's broken in the current stable xen 3.  Once I did that, name resolution worked.

Is the gateway configured? ('route -n')

What is in /etc/resolv.conf? It should contain 'nameserver x.y.z.t'
where x.y.z.t is obviously a willing nameserver.

See above for the gateway. Try with 'traceroute -n x.y.z.t' to see how
far you go.
