Trying to run up my windows project using Xamarin for windows phone 8. Kept getting this error when the windows phone 8.1 emulator

"Failed to start the virtual machine because one of the Hyper-V components is not running"

Researched a bit and had a few goes and quite a few different solutions but had to manually edit .vmx file which is inside the vmware folders.

Had to add

hypervisor.cpuid.v0 = "FALSE"

Make sure you do this with the VM shutdown. And bobs your uncle it now runs up the windows 8.1 emulators. Took a while to run them up the first time but it did finally come up. Can now debug my Xamarin project on windows phone 8.1.

Enjoy
