Running WinPhone emulator inside Win10 VMWare

I had a Win 8.1 hosted OS, running VS2013, and could test my WinPhone app in the emulator fine. The host OS is Win7 Pro.

I reinstalled the hosted OS to Win10, and VS2015, and now I get the Hypervisor not enabled error when I try to test my app with the emulator:

enter image description here

I've tried disabling and re-enabling HyperV (in the hosted OS) as per:

Unable to start the Windows Phone Emulator

But to no avail.

I've also tried opening the BIOS setup (PhoenixBIOS) of the hosted machine, but there are no options that I can see that would help.

What else can I try to get it working?

(And why oh why didn't I back up the VM first?!)

Solution

  • Into the Workstation run Powershell in elevated mode(Run as Administrator) and run

    Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V –All

    Stop Workstation and go to settings/processors/Virtualization engine and set:

    • Preferred mode: Automatic
    • Disable acceleration for binary translation: unchecked
    • Virtualize Intel VT-x/EPT or AMD-V/RVI: checked
    • Virtualize CPU performance counters: checked

    Start Workstation and Run lusrmgr.msc and check also your account is in the Hyper-V Administratiors group

    Check in the services that the HV Host Service and Hyper-V Virtual Machine Management are up and running.

    If Error 31: A device attached to the system is not functioning follow the steps from here.

    The fix is:

    • Shut down Workstation.
    • Open the registry (Start > Run > regedit).
    • Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hcmon.
    • Create a new key called Parameters.
    • In Parameters, create a new DWORD value entry named DisableDriverCheck, and then set the value to 1.
    • Reboot

    Appears this issue is for Windows 7 host. The fix worked on the few I tried.

    If Error 31 is still appearing run in the Workstation command prompt in elevated mode(Run as Administrator) and type

    bcdedit /set "{current}" hypervisorlaunchtype auto

    and then restart the Workstation.

    Check again in the services that the HV Host Service and Hyper-V Virtual Machine Management are up and running.

    Go to Network and Sharing Center/Change adapter settings and disable and re-enable all adapters with name: vEthernet (Internal Ethernet Port Windows Phone Emulator Internal Switch)

    And now you should run the emulator... ;)
