虚拟机的xml里面配置了串口没？

配置了
<serial type="pty">
<target port="0"/>
</serial>
<console type="pty">
<target type="serial" port="0"/>
</console>
Comment 3 xuchunmei alibaba_cloud_group 2022-10-24 10:37:06 UTC 
那么启动参数确定加上console=tty0,console=ttyS0,115200n8了？
grubby更新后重启了么？

确定加上了,确定重启了. 
同样的方法,在arm上没有问题.
Comment 5 wanqian alibaba_cloud_group 2022-10-24 10:44:18 UTC 
grubby --update-kernel=ALL --args="console=tty0 console=ttyS0,115200"  

串口配置:
<console type="pty">
        <target type="serial" port="0"/>
</console>
<serial type="pty">
        <target port="0"/>
</serial>

成功.

bug不需要修复 关闭

虚拟机xml配置问题，非OS本身问题。
