VirtualBox
Ubuntu下安装VirtualBox
参考文档：
wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -
echo deb https://mirrors.tuna.tsinghua.edu.cn/virtualbox/apt/ xenial contrib|sudo tee /etc/apt/sources.list.d/virtualbox.list
sudo apt-get install virtualbox virtualbox-ext-pack -y 注意：这里需要安装virtualbox-ext-pack，否则无法虚拟机开启远程桌面，就无法安装系统
命令行安装Ubuntu系统

映射主机的3390端口到本地电脑，然后用 RDP 远程桌面连接工具连接虚拟机远程桌面，Mac 系统推荐使用 Remotix
如何装Ubuntu，这里略过...
卸载Ubuntu安装ISO镜像
vboxmanage storageattach $vm --storagectl "IDE Controller" --port 0 --device 0 --type dvddrive --medium none关闭远程桌面
# 运行状态，关闭远程桌面
vboxmanage controlvm $vm vrde off
# 运行状态，开启远程桌面
vboxmanage controlvm $vm vrde on
# 修改配置，关闭远程桌面（需要关闭虚拟机）
vboxmanage modifyvm ${vm} --vrde off
# 修改配置，开启远程桌面（需要关闭虚拟机）
vboxmanage modifyvm ${vm} --vrde on
备份虚拟机系统(建立快照)
vboxmanage snapshot $vm take backup-20180418-001还原虚拟机系统(恢复快照)
vboxmanage snapshot $vm restore backup-20180418-001查看快照列表
xiaohui@tanmer-dev:~$ vboxmanage snapshot node1 list
Name: init-ubuntu-20180418 (UUID: 1960cff6-e827-4a8f-a0df-8bba2b580f23) *关闭虚拟机
vboxmanage controlvm $vm poweroff注销虚拟机
# 注销，不删除数据
vboxmanage unregister $vm
# 注销，并删除数据
vboxmanage unregister $vm --delete克隆创建的Ubuntu系统
当我们需要创建多个虚拟机Ubuntu系统时，我们没有必要每次都重复上面的安装步骤。我们可以用VirtualBox的克隆功能，快速复制个Ubuntu系统
通过快照克隆系统
# 通过node1的init-ubuntu-20180814快照克隆系统
vboxmanage clonevm node1 --snapshot init-ubuntu-20180418 --name node2 --register
# 启动node2
vboxmanage startvm node2 --type headless从node1克隆为node2之后，她的hostname没有改变，这里需要修改：
sudo sed -i 's/node1/node2/' /etc/hosts
sudo sed -i 's/node1/node2/' /etc/hostname
sudo hostname node2IP地址的设置也需要修改
sudo vi /etc/networking/interfaces启动克隆后的虚拟机，如果是Bridged网路可能会无法上网。可以通过一下方式解决：
vboxmanage controlvm node2 poweroff
vboxmanage modifyvm node2 --nic1 none
vboxmanage modifyvm node2 --nic1 bridged
vboxmanage startvm node2 --type headlessLast updated
