Windows Server 2016: Hibernate + Hyper V issue

Question

Hello,

I have Windows Server 2016 (ws2016) with hyper v enable
I'm trying to hibernate the machine

here is what I did:

Microsoft Windows [Version 10.0.14393]
(c) 2016 Microsoft Corporation. All rights reserved.

C:\WINDOWS\system32>powercfg -h on

C:\WINDOWS\system32>powercfg -a
The following sleep states are available on this system:
    Standby (S1 S3)
    Hibernate
    Fast Startup

The following sleep states are not available on this system:
    Standby (S2)
        The system firmware does not support this standby state.

    Standby (S0 Low Power Idle)
        The system firmware does not support this standby state.

    Hybrid Sleep
        The hypervisor does not support this standby state.


C:\WINDOWS\system32>shutdown -h
The request is not supported.(50)

C:\WINDOWS\system32>

Any idea on how to solve this?

thank you

Hi，

Please run Regedit and select the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentCongtrolSet\Control\Power. Check the value of the DWORD "HibernateEnabled" and set it to 1 if it's 0.
Also check the value of the DWORD "HiberFileSizePercent". If it's 0, it means 40%. To get the size of the hibernation file (C:\hiberfil.sys), you can multiply the percentage by the size of usable memory. Make sure there are enough free disk space for hiberfil.sys on C: Drive.

You could change the hibernation file size with
POWERCFG /HIBERNATE /SIZE

For more details you could refer to this article

Hi,
I'm afraid that when enabling Hyper-V, you are also disabling Hybrid sleep, to confirm this you can try and disable Hyper-V.
Check and see if Hybrid sleep is available, then enable Hyper-V again.
