Visual Studio 2017 Android Device Manager thinks WHPX is not properly installed

Question

I just update Visual Studio 2017 to version 15.8.0, the one that I've been waiting for a while now, due to its support for Hyper-V accelerated Android emulators using Windows Hypervisor Platform (WHPX).

I've been running Windows 10 version 1803 since May, and I have installed/enabled Windows Hypervisor Platform from "Turn Windows features on or off". Also, I have updated Android SDK and tools as it's described in https://docs.microsoft.com/en-us/xamarin/android/get-started/installation/android-emulator/hardware-acceleration.

However, when I run any of the accelerated emulators, I get an error:

We've encountered an error with your Windows Hypervisor Platform (WHPX) configuration that is preventing us from running your emulator accelerated.

Please ensure WHPX is properly installed, then perform a factory reset on the emulator and try again.

No log and nothing else. Hence, I'm a bit confused and don't know what I should do next.

Appreciate any help.

P.S. Couple of clarifications:

• I tried both, resetting existing emulators and creating new ones.
• I run Hyper-V virtual machines and Docker containers on the same PC.

Maybe the Virtualisation is not enabled for your CPU from the BIOS menu. Boot to your BIOS and Enable Virtualisation. Also, install or reinstall these features on windows.
