Hello,

here is my problem trying to start hyperv servers:

Start-VM : 'sql-svr' failed to restore virtual machine state. (Virtual machine
ID 087B53E0-613F-4689-93EC-689581CE094B)
Virtual machine 'sql-svr' could not be started because the hypervisor is not
running (Virtual machine ID 087B53E0-613F-4689-93EC-689581CE094B).
The following actions may help you resolve the problem:

  1. Verify that the processor of the physical computer has a supported version
    of hardware-assisted virtualization.
  2. Verify that hardware-assisted virtualization and hardware-assisted data
    execution protection are enabled in the BIOS of the physical computer. (If
    you edit the BIOS to enable either setting, you must turn off the power to the
    physical computer and then turn it back on. Resetting the physical computer
    is not sufficient.)
  3. If you have made changes to the Boot Configuration Data store, review these
    changes to ensure that the hypervisor is configured to launch automatically.
    At line:1 char:1
  • Start-VM -Name sql-svr*
  • ~~~~~~~~~~~~~~~~~~~~~~~

    k:VMTask) [Start-VM], VirtualizationOperationFailedException
  • FullyQualifiedErrorId : OperationFailed,Microsoft.HyperV.PowerShell.Comm

I've enabled DEP I've even enabled it windows via bcdedit.exe /set {current} nx AlwaysOn yet I still face this nightmare

Any suggestions?

    Good morning! We came across the same issue and discovered there are two recent KB that break Hyper-V on Server 2012 and Server 2012 R2. You will need to uninstall KB5009624 on Server 2012 R2. If you have 2012 OS the update to remove is KB5009586. After a reboot your guest VMs will start as normal. Hope this helps!

    Hi AdrianCilliers-9686,

    Thank you for your question and for getting in touch. My name is Samuel and I would be more than happy to help you with your query.

    Make sure your Windows 10 host installs the latest Windows updates, if not, please update it, see more details on this below:

    https://support.microsoft.com/en-us/topic/windows-10-update-history-83aa43c0-82e0-92d8-1580-10642c9ed612

    Also check If the VMs connect to the external VSwitch, check if you can ping the VM from external machines, also check if you can RDP to the VM from an external machine;

    You can try if reinstalling the Hyper V role on the WIN10 host might help;

    If it still doesn't work, I suggest doing an in-place upgrade on the host to verify the result.

    If the answer is helpful, please upvote and accept it as an answer.

    Microsoft Server 2012 R2

    Assuming this was the result of Jan 11th updates have you installed the out of band?
