KVM的HVM虛拟機使用非序列槽方式建立virsh console 連接配接

在去年寫的文章中，http://blog.csdn.net/dobell/article/details/14442457，寫到了怎麼利用serial 裝置進行console連接配接

不過比較麻煩，因為1.需要修改虛拟機内部的grub啟動選項，2 vnc連接配接過去無法同時使用

後來發現libvirt支援了virio啟動，那麼就容易了多了。

虛拟機配置檔案的xml如下

<devices> 
           

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

</devices>
           

然後virsh create  hvm201.xml建立虛拟機即可。

這次就不截圖了，具體如下

連接配接到域 hvm201

不過這樣還是有個缺點，grub還是得從vnc進入進行選擇，而且沒有記錄啟動過程中的資訊
