KVM的HVM虚拟机使用非串口方式建立virsh console 连接

在去年写的文章中，http://blog.csdn.net/dobell/article/details/14442457，写到了怎么利用serial 设备进行console连接

不过比较麻烦，因为1.需要修改虚拟机内部的grub启动选项，2 vnc连接过去无法同时使用

后来发现libvirt支持了virio启动，那么就容易了多了。

虚拟机配置文件的xml如下

<devices> 

 <console type='pty'>
        <source path='/dev/pts/5'/>
         <target type='virtio' port='0'/>
  </console>

</devices>

然后virsh create  hvm201.xml创建虚拟机即可。

这次就不截图了，具体如下

root@zju-PowerEdge-T610:/share/nfs181# virsh console hvm201
连接到域 hvm201
换码符为 ^]
