VBoxManage setextradata vnName “VBoxInternal/TM/WarpDrivePercentage” 200

VBoxManage is actually an .EXE script
where you can modify the advanced configuration of VBOX.

1) GO to Installation directory of your VirtualBox
2) Open Command Prompt from there
3) Type the command : VBoxManage setextradata “VBoxInternal/TM/WarpDrivePercentage”

Ignore the braces,

Example of actual command :
VBoxManage setextradata WindowsXP “VBoxInternal/TM/WarpDrivePercentage” 200

4) Hit enter

Do read this manual :

and this

Do correct me if i’m wrong

Well I found one solution to do this.
Go to
C:\Documents and Settings\\.VirtualBox\Machines\
and edit the xml file.
–>Create a backup of this file<–
Delete this line:

Note: the script vboxmanage setextradata “VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled” “1″ will create one line in this xml, so if you run more then once time you’ll see more lines. Delete these also.

Wayne, I haven’t confirmed, but I think if you set the 1 to a 0 (zero) on that command it will disable it.

Can someone tell me how to turn on the time sync feature… I turned it off successfully with this command

vboxmanage setextradata “VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled” “1″

… now I’d like to turn it back on.

Thanks
