Re: [Xen-users] how to enable dom0 and domu share same physical network...

["Tapdiya, Ashish" <ashish.tapdiya@xxxxxxxxxxxxxx>]

Specifying bridge=xenbr0 in vif parameter of config file is not working either 
since i am defining any bridge in /etc/network/interfaces of dom0.

I want the bridge in dom0 to act as a virtual hub and am following instructions 
from folowing web page for bridge networking scenario where all machines are 
within the same IP address range

Hello.

It could work either way, unless your DomU gets confused by the MAC
change no every boot. Generally, it's a good idea to define a static and
specific MAC to each DomU's vif.

This is not the complete output of "brctl show", is it? xenbr0 is the
here. Anyway, your issue is more clear now.

Silly me! Lukas is right, your vif definition needs a bridge definition!
As he said, "vif = ['ip=IP,bridge=xenbr0']" should work.

I would change that to "vif = ['mac=MAC,bridge=xenbr0']".

"vif = ['ip=IP,mac=MAC,bridge=xenbr0']" shall also work, but the IP
address is surely defined within DomU. Whatever you specify in "vif"
directive as IP address, will not be taken into account normally,
although sometimes it's useful to mention it in the config file for
reference.

(such weired way to quote original mail, but whatever)
