分析原因，是因为 Xen 是python写的，执行 Xen 相关工具时需要调用 python 相关库，如果版本对应不一致，或者库路径不一致，则会出错。

出现此报错应该是主机的libvirtd服务没有启动，而virt-install工具在进行客户机系统安装的时候错误地将客户机的网卡连接到libvirtd服务起的网桥virbr0上，此时libvirtd是关闭的，所以virbr0也不存在了，就出现了上面的错误信息。% |0 F% G* R$ V. H0 N; m
解决方法有两个：. p) V" ^$ E- Z
（i）启动libvirtd服务后重新用原来的virt-install命令安装客户机操作系统；

因为我使用的机器是好几年前的，系统是 Cent OS 5.2，不知道xen相关包有没有安装正常，于是使用 yum -y install xen* 重新安装了 xen 相关包，发现有几个包的确没有安装上 。安装完毕，重启系统后创建虚拟机，该问题不再出现。: F: Q S1 K) N8 r( ~$ Y2 k

网站上说，启动虚拟机桥接设备需要这样几个内核模块支持：netbk ，netloop，于是我使用 modprobe 命令手动加载了这两个模块，并且重新启动了 xend，这是生成了网桥设备 xenbr0，; P% E8 Y/ @0 L: i* {) t

这地方有问题，CentOS默认安装的是Python 2.4.3，库文件和可执行文件的路径是:
