How to crash dump a Guest running Windows 2008

Hi Folks,

I have a Windows 2008 VM running on Hyper-V (RTM) and I like to manually crash dump it.

Normally I would follow  http://support.microsoft.com/kb/928839 but that is for Virtual Server 2005.

Can someone either point me to the right KB or give me instructions on how I can crash my VM ?

thanks & appreciated
Rgds,
Edwin.
