Hyper-V Program Manager
Under certain circumstances with a Windows XP / 2003 operating system - intelppm.sys and processr.sys can cause a virtual machine running under Virtual PC / Virtual Server to crash (by default this will cause the Windows guest operating system to reboot automatically - but if you have changed this setting you will see a blue screen). The reason for this crash is because these drivers are attempting to perform an unsupported operation inside of the virtual machine (like upgrading the physical processors microcode, changing power state on the physical processor).
Today this problem only occurs on Centrino and AMD K8 processors. Most people see this problem when they move a virtual machine that was created on another type of processor to a computer running one of these types of processors (and then they usually see the problem when they attempt to shutdown their virtual machine for the first time). Now you may be wondering why you have not heard about this problem more often - and the reason for that is that if these drivers fail once - they are smart enough to not attempt to perform the operation that failed again.
If you are seeing this problem repeatedly you can manually disable these drivers (with no negative side effect) by going to the following location in the registry:
And changing the 'Start' value to '4'.
In the mean time we have made some subtle changes to the way our hardware exposes the processor in Virtual Server R2 so that in future products these drivers should never get loaded inside of virtual machines.
This article was realy useful to me. To prevent to spend so much time to reintalling again all stuffs...
Thank you too much, Thats works really good

That's for the heads up on this.
Just as a note though. I had to start the guest machine in safe mode so the registry entry I had to change wasn't "...\CurrentControlSet\..." but was "...\ControlSet002\..."
Thank you, thank you, thank you! Even here in 2010 this has brought my Sun VirtualBox back to life!
Solved my problems.
Moving a Guest XP 32bit from a 64bit Mandriva system to:
a 32bit Linux Mint host.
All on VirtualBox.
You are a wonderful person. I had this problem with a Centrino processor using Virtual Box and it was driving me crazy. Simply changed the registry as suggested for the intelppm and the problem went away. Thanks again
