Problem resuming after sleep with Hyper-V feature enabled


  • After enabling the Hyper-V feature, my installation doesn't resume from sleep and I have to reset my system after it enters sleep. If I remove the Hyper-V feature, wake from sleep starts working again. I can reproduce the problem any time I enable Hyper-V. 

    Any help will be appreciated.

  • To help determine if my problem was related to other software I had installed, I have performed a clean install of Win8.

    Vanilla Win8, no 3rd-party drivers or apps. All the latest updates. I verified that resume from sleep worked as expected and enabled Hyper-V. Resume from sleep is broken again.

  • Hi,

    According to Windows Server 2008 article, the sleep mode will be disabled if hyper-v is enabled. You can refer to this blog.

  • Hi,

    Unlike with srvr2008, sleep doesn't get disabled when Hyper-v is enabled. My problem isn't that sleep can't be used, but that resume doesn't work after entering sleep. Can anyone confirm the observed behaviour on his/her machine?

  • Sleep works normally on my Win8 w/hyper-v machines.
    Do you have a VM running?

    I don't have a VM running. Just enabling Hyper-V is enough to wreck sleep.

  • Which AMD processor do you have?
    Have you updated your motherboard BIOS to the most current version?

  • I have a phenom II  T1075 at home, I'll check sleep on that.  I don't
    normally sleep that machine. (it needs to be available remotely)

  • I think I have that same CPU, but different board.  I'll double-check tonight.

    On a side note, there seems (to me anyway), a higher number of issues with virtualization and Gigabyte MBs on the forums than other brands.

    If you're talking about Server, I'd agree, but we aren't talking about
    server, just Widows 8.
    Microsoft did a lot of work on putting Hyper-V on a client OS and
    making it work correctly in that environment and workload.

  • >virtualization came from the data center, bolting on Hyper-V
    >to 8 is a poor man's server
    Er, no, that's not the target of Hyper-V on Windows 8, it's for
    development and testing, not to use as a server.
    If you want to use something as a cheap Hyper-V Server, going with
    Microsoft Hyper-V is a smarter move, it's built to take a server load.

  • >Hyper-V is free but it has a user snarky command line interface
    Very true, but if you're running a server you really should be able to
    handle it and there are tools that will run a client OS to administer

  • I'm only using Hyper-V as a vmworkstation replacement. Some testing and small environment building for personal education. I don't need the guest running all the time, that's why i would love to keep using the powermanagement features of the host. As Bob mentioned, MS did a lot of work to make Hyper-V working on Win8 so why not use it.

    I only hope i can get it to work without resorting to buying new hardware.

  • I have this exact same problem with Windows 8 RTM running with an AMD Phenom II 955 Processor and GA-MA78GM-S2H motherboard.

    Sleep works just fine when Hyper-V is not installed but any time I turn it on, the computer will not wake from sleep.  Regardless of if I actually have a VM on the host at all.

  • There aren't any Win8 drivers available with Gigabyte and the Win7 drivers are too old. Is there a way I could start troubleshooting the issue of should i try to log a call with MS?

  • I have the same problem with the a system I put together using a Gigabyte GA-MA785GPM-UD2H motherboard and a AMD Athlon II X3 435 CPU.

    I haven't yet checked for new drivers or firmware. But I added a "hibernate" option to the power-off menu. This is not quite as instantaneous as coming back from sleep mode and you need to lean over and press the power on key. But It saves my work state and it good enough for me for now.

  • Just to add my voice, I have exactly the same problem.  Gigabyte motherboard (GA-MA785GMT-UD2H) Windows 8 install fine.  Put Windows Phone 8.0 SDK on (which enables Hypervisor for the emulator) and the resume from sleep problem begins. 

    I can disable Hyper-V from BIOS and all is OK again, but then I can't do any Windows Phone 8 dev because the emulator won't launch without Hyper-V :\

    This is the second major flaw I've had with Win 8 since my switch to it, can't say I'm very impressed :\

  • Wipe and install windows 7 then upgrade to windows 8 on my brand new windows 8 laptop? Is there an explanation for this issue? Im not sure I would class this as a solution
    Friday, October 25, 2013 7:30 AM
  • Sorry, it's not Windows 8, it's your Gigabyte board.  Gigabyte MBs have some serious issues with virtualization.
