Q. Is it true that Hyper-V in Windows 2008 R2 supports hibernate and sleep?

A. This is true and false. With Windows 2008 R2, if you have a configuration that sets the hypervisor not to run, then you can now set the machine to hibernate. If the hypervisor is enabled, you can't hibernate. To create a boot option without the hypervisor loaded perform the following:

C:\>bcdedit /copy \{current\} /d "Windows 2008 R2 - No HV"
The entry was successfully copied to \{857781f4-1ff6-11de-bc04-bf483ae46187\}.

C:\>bcdedit /set \{857781f4-1ff6-11de-bc04-bf483ae46187\} hypervisorlaunchtype off
The operation completed successfully.

Note that the ID used in the second command should be the ID returned from the first command. You may also need to run "powercfg -hibernate on" to enable they hibernate capability.
