Android SDK and Intel HAXM

Question

I am running Windows 8.1 on a fairly decent piece of hardware. The CPU is a Intel Xeon E5-1620-v2 @ 3.7 GHz accessing 16 GB of RAM. So my processor definitly supports VT-x which is needed according to this article Speeding Up the Android* Emulator on Intel® Architecture.

However the installation package complains with:

This computer does not support Intel Virtualization Technology (VT-x). HAXM cannot be installed. Please refer to the Intel HAXM documentation for more information. 

I am running Hyper-V on this machine, so I am pretty sure VT-x is enabled. Any input on this?

Answer 1

Make sure that Microsoft's Hypervisor is disabled/uninstalled from system features.

When enabled Windows will boot into a light virtual session. This prevents another hypervisor from using the hardware because the system is already virtualized.

Edit: If you don't want to completely nuke Hyper-V, Scott Hanselman has a solution, where you can edit your boot menu to enable/disable Hyper-V.
