S3/S4 are disabled by default. Did you enable them in qemu?

Yes, I have added "-global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0" in my cli.

win2012r2 hit this problem.

I attempted to reproduce this upstream (qemu 2.2 rc2) and here is what I saw:

1) Installed Windows 2012 r2 (with updates) x86_64
2) Booted and typed POWERCFG /HIBERNATE ON. Command completes silently.
3) Typed "shutdown -h" to initiate a hibernation.
4) Qemu completes this action and closes.
5) Started qemu again.
6) Verified that my command line and several other windows that were open were still available, confirming the hibernation and resume completed successfully.

However, I will say that the "power" menu doesn't show the hibernate option. Is that a bug? Hibernate is clearly working and available here.

I am not aware of why the "Hibernate" option does not show in the menu after configuring it to via the Control Panel GUI. What is the actual behavior on physical hardware, do we know? Can this be identified as a QEMU bug?

QE: Do you have the ability to confirm that this behavior differs from a physical installation of Windows 2012 R2?

Hello guys,

I performed below test for Windows 2012 R2 on both UEFI and BIOS based firmwares, plus a SeaBios Based Win2012r2. 
though such interface thing should not relevant to firmware types:

per https://bugzilla.redhat.com/show_bug.cgi?id=995388#c0


Steps to Reproduce:
1. enable hibernate:
 powercfg /h on
 powercfg /a
The following sleep states are available on this system:
    Hibernate
    Fast Startup
2. go to Control Panel -> Hardware -> Power Options -> Change what the power buttons do -> When I press the power button: Hibernate 

                                                                                                                                                     ^^^^^^^^^   there's not hibernation option

* only * when goto the desktop, then press 'alt+f4', Windows will prompt what do you want to do next:
1) power off
2) reboot
3) hibernate

So I think this is a Windows interface policy, it dont suggest you to hibernate your machine through GUI.
then I did "shutdown /h" in cmd as Administrator

Yes, it hibernated, and when press power botten, it resumes, and system log could see it's from sleep state.



====================
SeaBIOS based Win 2012 R2 test:

boot a Win2012 R2 VM with scsi-hd and s3 s4 enabled as C#1 mentioned.

then redo the steps to reproduce, still *no hibernation in shutdown menu*, only appeared after pressing 'alt-f4' on desktop.
the 'powercfg /a' in cmd could see hibernate also.


So, Based on above physical(uefi and bios based) and VM(seabios) test, I think this should be a Windows GUI policy, does nothing relevant with virtualization.

Ah, I mean uefi and bios based physical machine :-)
on HP Compaq 8200 Elite MT (Dual firmware, both uefi and bios, switchable in configuration.)

Thank you very much for the confirmation!

Closing as NOTABUG since this seems to be Windows Server GUI policy and a problem with informational consistency in Microsoft's product, not ours.
