Xenbr0与peth0
Xenbr0设备用于表示网桥本身。网桥自己必须与服务器里的物理 以太网板通信。物理板通过peth0接口表示。由于它只是物理网板的表现形式，你通常不用直接管理它。你所需要做的是与peth0通话，在domain 0环境是eth0接口。它实际上是用在domain 0里的虚拟接口。每台虚拟机（域）都有一个eth0，取决于eth0的配置，可能还有其他的eth。
Eth0与vif
eth0接口是虚拟机所用的接口，所有这些接口需要在domain 0有所表示。它们就是vif接口，直接连接到Xen网桥，并使虚拟机与其他机器通信成为可能。所有的vif接口都有个名字，例如vifx.y。在此名字 中，x相当于显示在xm list命令中的虚拟机数量，y表示这台虚拟机的接口数量。例如，如果ID1虚拟机有两个网络板，你在domain 0机器上将看见vif1.1与vif1.2。
