原文链接：关闭VirtualBox虚拟机的时钟同步
在VirtualBox的虚拟机上默认虚拟机的时间是会和物理机同步的，但可以通过下面的命令来关闭
1. 首先查看虚拟机列表
1 VBoxManage list vms
2. 使用下面的命令来关闭虚拟机的时钟同步功能
1 VBoxManage setextradata “<VM_NAME>” “VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled” “1″
3. 如果先重新开启虚拟机时钟同步功能，可以使用下面的命令
1 VBoxManage setextradata “<VM_NAME>” “VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled” “0″
