Enable Hibernation and Sleep in Windows Server 2008 R2 when install Hyper-V Roll 

Normally when you install Hyper-V role in your server, it will disable sleep and hibernate facilities provided by Windows.

But you can avoid this by doing some alterations to Windows.

Hibernate and seep features are disabled when the Hyper-V service is started, so you can regain hibernate and sleep by changing the start parameter of the Hyper-V service (hvboot).

To change,

1. Open the registry editor by typing “regedit” in the run window.

Locate the key,

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hvboot and then set the start value of it to 3.

Start property can hold the following values.

0	Boot (Not supported by hvboot.)
1	System
2	Auto
3	On Demand
4	Disabled

Now you will have the hibernate and sleep facilities until you start the Hyper-V services in your machine.

2. Type the following command in a command prompt window with administrative rights.

sc config hvboot start= demand

Note that there needs to be a space between the = sign and the word demand
