Hibernation under Virtual PC

One little known fact about Virtual PC and Virtual Server is that with both of these products – it is possible to ‘hibernate’ the virtual machine if you wish to.  However most people never do this because one of the drivers that gets installed as part of the Virtual Machine Additions disables the hibernation feature.  If you want to hibernate a virtual machine – uninstall the Virtual Machine Additions and give it a shot – otherwise saving state is better in most situations.
