Complete!

 

 

  1. 查看安装完后

[root@server-3~]# virsh version

Compiledagainst library: libvirt 6.0.0

Usinglibrary: libvirt 6.0.0

Using API:QEMU 6.0.0

Runninghypervisor: QEMU 4.2.0

 

 

  1. 重新启动服务并设置为开机自启

[root@server-3 ~]# systemctl start libvirtd

[root@server-3 ~]# systemctl enable libvirtd

 

  1. 创建并启动虚拟机

[root@server-3 ~]# virt-manager

bash: virt-manager: command not found...
