安装基本网络工具
sudo apt install net-tools
修改root密码为vm
输入 sudo passwd 命令，然后会提示输入当前用户的密码。
按enter键，终端会提示输入新的密码并确认，此时的密码就是新的root密码。
修改完毕以后，在执行su root命令，此时输入新的root密码即可。
新增SSH免密登录
cd ~
mkdir .ssh
echo ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAyq1pB5aF0w6ps4OzwQl1C8uP41Iq7J+gqylLMXkoESrTUVhH1+irHuImxi2At886sO7x9s+b4jhRZoJZpZURPU4UmzUEBHKoXlqOf9eO//GtUita2AaPFw5tc0YgLPrgnO+z5MKfjo20aoJtVBvleRA/0YJcWy1a6ufXa8944D8a1Dirc9uVNR5QjKVFRbQt/twLkLdFB6t16HCwISKCVI56DcJOoY2g7mXI8clKaESeB+ANIhSKJclPwjoC6P0pHFfgqNauxC+0xugx3W2ZSIkVhdZu1L7iKvzXXPiETjPQA6qMjp/1dY2WU49Lf+wDOQplCy4HLq7QqNNVSzIBGw== Administrator@PCOS-1407251925 >> ~/.ssh/authorized_keys
SSH启用允许root远程连接：
sudo vim /etc/ssh/sshd_config
- 将
PermitRootLogin这一项取消注释，并改为yes
#LoginGraceTime 2m
#PermitRootLogin prohibit-password
PermitRootLogin yes
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10
安装qemu-guest-agent
