[Xen-users] Dom0 networking bridge setup DomU not accesible from Dom0 network


I have a CentOS 5.7 setup with virtualization activated during 
install. The NAT default network seems to work but i wanted another 
network setup since im trying to setup a paravirtualized router/gateway 

I followed the directions from this link: 

And also looked at Libvirt pages for more information but my current 
problem is this:

I have three network cards in the server, on is setup with a static ip 
adress and no bridge. and the other two network cards is setup 
according to example 4 on the wiki. (Example 4: A single bridged 
network with no local IP address: /etc/sysconfig/network-scripts/ifcfg-
xenbr0 )

Both bridges have been added to the DomU and they are visible in the 
install, interface eth0 in the domU is configured as a DHCP and gets 
the IP adress from my ISP service, Interface eth1 is setup with a 
static ip-adress,  ( and my clients are configured with 
adresses from

The problem i have is that i cant get a connection to the DomU if i 
ping i get no answer.

since i have read the wiki, and the libvirt page and haven´t found a 
solution to the problem i was hoping that the Xen community could help 

Anyone got any ideas?

Best regards
