VirtualBox error

VirtualBox error

I used Disk2vhd to produce an image of my XP laptop and tried to run that as a virtual machine in VirtualBox OSE on my Ubuntu netbook.

On trying to start the virtual XP machine I kept getting:

virtualbox driver_unloaded_without_cancelling_pending_operations

Online help says to use to safe boot the virtual nachine, then use regedit to change these key values:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Processor

and

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Intelppm

by changing the 'Start' value to '4'.

I also had to do this - and this is not anywhere online - for

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\amdppm

You also have to repeat this for

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\...
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\...
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Services\...

etc.
