A configuração de ponte Xen não faz a ponte entre eth1 e xenbr0

Question

Eu sou novo em Para-Virtualização. Eu usei o Xen Beginners Guide para instalar o Xen e configurar o dom0, ele funciona corretamente, mas não consigo configurar a bridge network para domU.

Eu criei uma imagem do Debian assim.

xen-create-image --hostname=weblinux --vcpus=2 --lvm=vg0 --bridge=xenbr0 --ip ***.***.***.225 --pygrub --dist=wheezy

Quando o serviço xendomains é iniciado, a interface peth1 é exibida. Eu não sei o que é isso. Tem o mesmo mac address com eth1.

Eu quero usar a interface eth1 para o host domU da bridge e eth0 para o acesso dom0.
