I have a Centos 5.5 server with Xen 3.2 and libvirt for virt-manager installed. Before installed libvirt I have the bridge configuration just like the documentation on Xen says:
xenbr0, eth0 and peth0 interfaces.
After installed libvirt my configuration got:
eth0, peth0 and virbr0
So the virbr0 was added instead of xenbr0, I read the documentation and this is a NAT adaptor for libvirt. So in order to get a bridge adaptor I got this guide:
But my peth0 is still up so I presume that xen bridge is still up. Can someone explain me how to proper setup a bridge network interface with Xen and libvirt because with the guide I followed I got a new adaptor called br0 which is the bridge but it has the same MAC address of my eth0 NIC.
I will apreciate any help.
