Xen users - Apr 2006 - Xen 3.0.2 and DHCP from domU

Hello,

I am running Xen 3.0.2 on a regular Intel P4, with the default network 
setup.  My problem is that my domU''s DHCP requests do not seem to reach
the outside world.   I can see them if I tcpdump in dom0 on xenbr0, but 
I cannot see them from another machine plugged into the same switch as 
my Xen machine.  This external machine _can_ see the DHCP requests made 
when dom0 makes its initial requests.  I can''t think of anything that 
might cause this.

Any ideas?

Thanks!
-Jon

I''ve run into this problem too.  I ended up setting up a dhcp-relay on
the
dom0 and configured it to forward all requests to my dhcp server.  No
problems after that.

I''m not entirely sure thats the "correct" way but it worked
for me.  If
anyone has any other suggestions, I would love to hear them.
