Unable to Launch Windows Phone Emulator

I am trying to run unit tests on our CI server. When i run the following command it tries to launch emulator but fails with the following message

vstest.cons         


        

Answer 1

I had the same problem. This fixed it.

Shut down the VM, select option “Virtualize Intel VT-x/EPT or ARM-V/RVI” in the vm processor settings.

Then add these two lines to the end of the vmx-file:

hypervisor.cpuid.v0 = "FALSE"
mce.enable = "TRUE"

Start the VM, add the Hyper-V components and restart the vm. Next time you start the emulator, Visual Studio will configure Hyper-V and run the emulator

Ok, I've successfully fixed this issue. But I've my particular scenario, so I don't know if it can solve for you too. My scenario is as follow:

1. I'm developing for Windows Phone 8, using a iMac 10.9.1 OSX;
2. I'm using the VMWare Fusion 6, with Windows 8.1 imported through bootcamp;
3. I'm using Visual Studio 2013 Ultimate, running the emulator from it;
4. I was receiving that error in every manner that I used to launch the Windows Phone Emulator.

To fix the issue:

1. You must use Hyper-V (VM Settings -> Processors & Memory -> Advanced options -> [Enable hypervisor applications in this virtual machine] must be checked), only changeable with VMWare turned off;
2. To use Hyper-V, your VMWare must have at least 2 processors. It can be set with VMWare turned off in the same window of item 1;
3. In VM Settings -> Advanced -> Preferred virtualization engine, select Intel VT-x with EPT;
4. Open the directory where you VMWare image is located, and open it with [option] button holded. Click in [Show Package Contents] and locate the .vmx file. Open this file with a text editor and put/modify these lines:
   • hypervisor.cpuid.v0 = "FALSE"
   • mce.enable = "TRUE"
   • vhv.enable = "TRUE"
5. I've followed these references:

I hope that it helps you too!

You have not installed Hyper-V properly. "Hyper-V platform" should be installed for the service to run. Normally VM's have a "hypervisor" running by default and Hyper-V requires this hypervisor to run itself.

So first disable the hypervisor of the VM by altering the "vmx"(in case its vmware) file of your virtual machine(BACK UP THE FILE BEFORE MAKING CHANGES!)

off your VM

locate the .vmx file

If you cant fiond the vmx file read this article - http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003880

open it with notepad and add this line at the end(or anywhere actually)

hypervisor.cpuid.v0 = "FALSE"

If you cant find the vmx file read this article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003880

Now you will be able to install the "Hyper-V platform" in windows "turn windows features on or off", do that.

restart

Try deploying to WP Now! If it is still not working please comment the error you get!

After enabling support for VTx in your BIOS, you might want to check your system by running the Codeinfo tool.

Also, don't forget to enable "Hyper-V Management Tools" and "Hyper-V Platform" on "Control Panel->Programs and Features->Turn Windows Features on of off->Hyper-V":

I am running Windows 8 64 bit inside VMware player on top of a windows 7 machine. Also had problems running the emulator from windows phone 8, and solved them by following this guide: http://developer.nokia.com/Community/Wiki/Windows_Phone_8_SDK_on_a_Virtual_Machine_with_Working_Emulator

Hope it helps...

Answer 5

Just copy your vhd and other files from the vhd location to another folder. Just create another a new VM with the VHD which you just copied. Now it will start.

Answer 6

Make sure you select the option “Virtualize Intel VT-x/EPT or ARM-V/RVI”. This is required to be able to run HYPER-V on your virtual machine.
