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:
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?!)
The emulator is running a system image created for an x86-based virtual device. You can't run a VM-accelerated emulator inside another VM, such as a VM hosted by VirtualBox, VMware, or Docker (unless using WSL2). You must run the Android emulator directly on your system hardware.
Download and install Android StudioGo to the Android Studio download page from the browser inside your instance. Follow the instructions to install Android Studio on your VM. Follow these instructions to create a new AVD configured however you like.
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:
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... ;)
