在 RHEL-5.8 安装 XEN 时报错如下：
ERROR POST操作失败: xend_post：来自 xen 守护进程的错误：(xend.err 'Device 0 (vif) could not be connected. Hotplug scripts not working.')域安装似乎没有成功。如果是这样，您可以运行 'virsh start vm02' 重启您的域，否则请重新开始安装。ERROR POST操作失败: xend_post：来自 xen 守护进程的错误：(xend.err 'Device 0 (vif) could not be connected.

解决方案如下：
① 先查看 xendomains 的状态：service xendomains stop/status/start
② 如果被stopped、而且、手工start起不来、则可先 touch /var/lock/subsys/xendomains
接下来便可以顺利运行 virt-install
