在KVM Guest虚拟机中添加串行端口时出现错误-只有第一个控制台可以是串行端口

Question

我遇到错误（3月19日20:19:22 SDP-2初始化：串行（ttyS0）主进程结束，重新生成 Mar 19 20:19:22 SDP-2 init：initLogger主进程（608793）终止，状态为1）。为了解决此问题，我从来宾xml文件的节中删除了该行：

<controller type='virtio-serial' index='0' ports='16'>
      <alias name='ua-9452f44a-2df1-41ea-b037-60c777eb21c4'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>
    </controller>

我现在如何在访客xml文件中添加串行端口？我试图在访客xml中添加以下内容：

 <console type='pty'>
    <target type='serial' port='0'/>
    <alias name='serial0' />
    </console>

下面是我的来宾xml中的代码。如何添加串行端口以消除错误“ 5月8日15:02:51 SDP-A sudo：apache：TTY =未知； PWD = / var / public； USER = root； COMMAND = / bin / rpm -q Duser” 。

我想添加串行端口，但是在添加时出现错误“只有第一个控制台可以是串行端口”。
