先安装桌面环境，参考：https://blog.51cto.com/helpdesk/5143119

然后安装qemu,kvm及virt-manager（类似virtualbox的虚拟机管理器）

sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virt-manager

启动服务

sudo systemctl start libvirtd
sudo systemctl enable libvirtd
sudo systemctl status libvirtd

进入桌面环境，在Terminal命令行界面输入：

virt-manager

即可见软件界面

找iso时如果提示Permission Denied，则注意不要放在用户home目录下
