I have Windows Server 2012 installed on a laptop. I need a server because I develop software that I need to test specifically on a server edition. Documentation for Windows Server 2012 says

Sleep and hibernate are no longer disabled when the Hyper-V role is installed.

What value does this change add?

Computers running Hyper-V can be put into sleep or hibernate mode. This is particularly useful to users who are running Hyper-V on laptops computers.

Question

How to enable hibernation on Windows Server 2012 with Hyper-V role?

Things I tried

  • Modify registry for hvboot. I did not have hvboot folder in the registry, so I added it manually, rebooted

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hvboot]
"Start"=dword:00000003

    No effect.

  • Pressed Alt+F4 on desktop, no Sleep or Hibernate available

shut down options

  • Stop Hyper-V Virtual Machine Management service in service.msc (which points to C:\Windows\system32\vmms.exe), all other Hyper-V services were stopped by default.

  • Executed as Administrator

    powercfg.exe /hibernate on

    This is the output

    Microsoft Windows [Version 6.2.9200]

C:\Windows\system32>powercfg.exe /hibernate on

The article you linked to is in error. This is a feature expected to be a part of 2012R2. That section of the article should be labeled as requiring R2.

  • I wonder what will happen to the guests when the host goes into hibernation... – Ryan Ries Aug 13 '13 at 12:40
  • @RyanRies from the article: "When entering sleep or hibernate Hyper-V will save running virtual machines. When coming out of sleep or hibernate Hyper-V will attempt to restart the virtual machines that were running before entering sleep or hibernate." – longneck Aug 13 '13 at 13:13
  • This feature exists in Client Hyper-V for Windows 8, but not in Server 2012. No idea what it's doing in that Technet article, as it's clearly erroneous. – Michael Hampton Aug 13 '13 at 14:19
  • @MichaelHampton The article was updated to include details for R2. When they made the change, they should have noted the R2 requirement for that feature. – longneck Aug 13 '13 at 14:34
  • The behavior seems to persist in 2012r2. I'm running it and get the same powercfg output as the OP. – EricB Jan 11 '15 at 10:56
