Xen Bridge 配置不桥接 eth1 到 xenbr0

我是半虚拟化的新手。我曾经Xen 初学者指南安装 Xen 并配置 dom0 它可以正常工作，但我无法为 domU 配置桥接网络。

我创建了这样的 debian 图像。

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

当 xendomains 服务启动时，peth1 接口出现。我不知道它是什么。它与 eth1 有相同的 mac 地址。

我想使用 eth1 接口来桥接 domU 主机，并使用 eth0 来访问 dom0。
