  • Thread-topic: cannot ping vms created on ubuntu oneiric (11.10) dom0 + natty vm

When I create a vm using a default dom0 network interface as eth0, I cannot  
ping the vm. 

I notice that a virbr0 bridge is  created. I had never seen this virbr0 when 
running Debian dom0s. I removed virbr0 by erasing the nodes in the default.xml 
file specifying this bridge.

I still could not ping my vm.

Do I need explicitly to create a bridge called eth0? I never needed to to this 
when running dom0 on Debian.

In a proper setup, would I have a network interface called eth0, and a bridge 
called eth0, both expicitly defined in /etc/network/interfaces?

If so, do I give the bridge the same address information as the primary network 
device, eth0?
