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://learn.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.
Running from VS2019 gives me the same WHPX error. But running manually works just fine with hardware acceleration (make sure you run powershell as administrator):
PS C:\Program Files (x86)\Android\android-sdk\emulator> .\emulator.exe -avd <avd_name> -feature WindowsHypervisorPlatform
I received this error even though I was already successfully running docker containers as well.
It turns out that I didn't have Windows Hypervisor Platform enabled in the "Turn Windows Features On and Off" menu. Once I turned it on, the error disappeared.
I had both Hyper-V options enabled but not Windows Hypervisor Platform. I guess that one is not required to run docker containers.
Work with visual studio 2019
I fixed this issue by disabling "Windows Hypervisor Platform" and only enable "Hyper-V" option.
It may be that your CPU does not support virtualization or some other software is preventing its use. If you have an Intel Processor Intel's VTx support page is an excellent resource to determine if your CPU permits virtualization and/or if some other software is preventing its use:
In summary:
Identify Your Intel CPU and View the Specs
Use the Intel Processor Identification Utility (https://www.intel.com/content/www/us/en/support/articles/000005495.html).
As the first link points out, even if the Intel tool in #2 shows VTx not supported, check TaskManager to see if Virtualization is enabled. If it is, then some other software is using Virtualization and preventing the tool (and other tools similar to it) from showing Virtualization as enabled.
Using both Intel's utility and TaskManager you can diagnose the problem per Intel's Table:
Virtualization Checked in Intel Utility + Virtualization Enabled in TaskManager -> enabled, usable
Virtualization Checked in Utility + Virtualization Disabled in TaskManager -> disabled in BIOS.
Virtualization Checked in Utility + Virtualization Enabled in TaskManager -> enabled but used by other software
Virtualization Checked in Utility + Virtualization Disabled in TaskManager -> Virtualization not supported .
I am running android studio on Elementry OS. I have installed kvm and it's properly installed...see below screenshot...
but when i try to run emulator in android studio it's giving me following error...
Steps to enable Virtualization:
Power on the machine and open the BIOS.
Open the Processor submenu The processor settings menu may be hidden in the Chipset, Advanced CPU Configuration or Northbridge.
Enable Intel Virtualization Technology (also known as Intel VT) or AMD-V depending on the brand of the processor.

I recently installed Android Studio, and could successfully use AVD Manager, at beggining. But suddenly it stopped working due to following error:
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: HAX kernel module is not installed!
I have tried to install & run HAXM manually, but problem is that I have Windows 7 Home Premium and don´t have Hyper-V option. Reasonably, I cant install HAXM!
Whether you have VT is a function of the BIOS and processor. You don't have to have Windows hypervisor to use Virtualization, in fact you have to turn hypervisor off on systems that have it. Check your BIOS and download HAXM from - https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager
Also turn off Avast is you're using it for antivirus
I installed Android studio in my windows 7 OS and it doesn't allow me to load AVDs. It shows this error.
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: HAX kernel module is not installed!
I tried several things. I enabled "Intel Virtualization Technology" from the BIOS setup and re-installed XHAM installer from SDK Manager. But nothing changed. At last I tried to install "intelhaxm-android.exe" at the file location but it gives an error as below...!
"This computer meets the requirements for the XHAM, but intel
virtualization technology (VT-x) is not turned on. XHAM cannot be installed
untill VT-x is enabled. Please refer to the Intel XHAM documentation for the
information"
But I have already enabled it from the BIOS!!
Your computer can only use one type of VT at a time. That's why many Windows 8 users are having trouble with Hyper-V. Avast Antivirus (and probably others) also use this. You can either uninstall your antivirus software, or search for the option that uses virtualization. In Avast, you can do it as seen in the picture. You have to reboot your computer after this change.
To run the AVD with HAXM you require both the HAXM packages from the SDK manager along with installing https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager from intel.
Ensure that VT is enabled in your bios and then try again. There is also a guide on the intel site that explains how to enable this: https://software.intel.com/en-us/android/articles/installation-instructions-for-intel-hardware-accelerated-execution-manager-windows
Lately Google and Intel have published a new way to run the emulator, which should work much better than the previous version (which has emulated ARM CPU). Here are some links about it: this and this.
However, after installing the new components and creating a new emulator configuration as instructed, I get an error and I also can't see any improvements. I've tried both API 10 and API 15, and with GPU enabled and disabled. None of those configurations helped. I've also tried it on two different computers and didn't get any boost (and got the same errors).
It seems that on the posts I've read about it, nobody had any problems with it and all report a much faster emulator.
The error it shows is:
emulator: Failed to open the HAX device!
HAX is not working and emulator runs in emulation mode
emulator: Open HAX device failed
Why is it happening, and is there a way to fix it? Is there anyone else who gets those errors or vice versa?
By the way, I have an Intel CPU, if that could be a problem.
EDIT:
here's what I see in the BIOS, so it should be available... :
I had the same issue, solved it by Installing the Intel Hardware Accelerated Execution Manager. Download it with the SDK Manager, it's in Extras. After this, go to the folder
[Android SDK Root]\extras\intel\Hardware_Accelerated_Execution_Manager
then run IntelHaxm.exe and install.
Here the link of the Intel Hardware Accelerated
IntelHaxm.exe for
Microsoft Windows,Mac OS* X, and Linux
Ubuntu
You'll get the following message if you don't have virtualization enabled in your BIOS:
Small Note for Windows 8 user, Intel HAX will not work if Hyper-V feature is enable. Hyper-V (like most of the virtualization tech) will exclusively lock the VT extension witch will prevent HAX to work properly. A workaround if you “need” Hyper-V too might be to stop manually the Hyper-V services when you need HAX (haven’t tested it yet through).
If all else fails. Simply try to download the Intel HAXM zip manually, extract and install.
check here
Remember this only works for an Intel cpu that supports Intel Virtualization Technology. And you MUST enable virtulization in your bios.
It's a fairly decent and very noticeable improvement to the android emulator if you ask me.
Not every processor is supporting the virtualization!
To find out your chipset abilities go to http://ark.intel.com/,
insert the name of your processor in the search line and check out the resolve.
Advanced Technologies: ...
Intel® Virtualization Technology (VT-x) = ???
If you see "No", you can forget HAXM!
Here are the steps to get the Hardware Accelerated Execution (HAX) which is really quite a lot:
1-check your processor Intel website to see if it supports Intel VT-x or not:
http://ark.intel.com/Products/VirtualizationTechnology
all Intel Core i processors and some other selected processors support Intel VT-x
2- check your bios to enable Intel VT-x , usually called hardware virtualization or Intel virtualization in bios
3- check if you are using a software conflicting with HAXM, popular software conflicting with haxm include but not limited to:
Hyper-V
Windows phone SDK 8
Avast antivirus 8
4-install Intel management engine interface (MEI), this driver is usually not installed and is not part of retailer Windows DVD, even Windows 8.
Check this post about how to install:
http://communities.intel.com/community/vproexpert/blog/2011/12/19/mei-driver-now-available-via-microsoft-windows-update
This driver is required and is not optional to activate Hardware Acceleration
you can also install it from windows update
5-use android SDK manager to download Extras -> Intel x86 Hardware Accelerated Execution Manager.
6-Run installer of HAXM from:
[Android SDK Root]\extras\intel\Hardware_Accelerated_Execution_Manager\IntelHaxm.exe
if you passed the previous steps the installer will work just fine ,otherwise it will fail
7-start AVD and see the difference in performance, Animations are faster
System UI and launchers crashes in 4.0.3 but are just fine for 4.2.2
see installation guide by intel:
Using SDK Manager to download Intel HAX did not work.
Downloading and installing it from the Intel website did work.

Top Tip: making the change in my BIOS to enable virtualization and then using "restart" did not enable virtualization. Doing a cold boot (i.e. shutdown and restart) suddenly made it appear.
The first step (on Windows) is to make sure that the Micrsoft Hardware-Assisted Virtualization Tool reports that "this computer is configured with hardware-assisted virtualization".
http://www.microsoft.com/en-us/download/details.aspx?id=592
You might need to turn on virtualization in your BIOS, most manufacturers disable it by default. Intel HAX requires CPU virtualization to be enabled.
The same began to happen to me about one week ago, without apparent reason (99% sure that I didn't upgrade anything); after being able to run the emulator for some time it just stopped working without an apparent reason.
I tried to install the Intel thingie, but the installer reported that my machine doesn't support Intel VM, despite the fact that it has an Intel i3 processor and that virtualization is enabled (perhaps XP is too old an OS for that, although MS VM, Oracle's Virtual Box and VMWare have been installed an working in this machine with the same OS).
I just edited the VD to emulate an Arm processor, and everything is working again.
Perhaps not the optimal solution, but it works!
For Windows, there are some answers explained how it works. But I'm a Mac User, I don't know how to install HAX driver for Mac as they did for Windows. Finally I found the below link and it did fix my problem. You should download HAXM of Mac
and then install it.
https://software.intel.com/en-us/articles/intel-hardware-accelerated-execution-manager-end-user-license-agreement-macosx/
Complete step-by-step instructions for running the accelerated emulator can be found on the official Android developers website:
Caution: As of SDK Tools Revision 17, the virtual machine acceleration
feature for the emulator is experimental; be alert for
incompatibilities and errors when using this feature.
You have to download the Intel® Hardware Accelerated Execution Manager.
Then you will get this message:
Starting emulator for AVD 'test'
emulator: device fd:740
HAX is working and emulator runs in fast virt mode
For Mac users who want to check whether your processor supports virtualisation, use the maccpuid software and look for VMX. If it is checked then you're good to go.
Download it here
Here there are two issues we have to concentrate on:
HAX device failed to open,
For this problem, you have to run the HAX device setup file from the HAX addon folder. Follow Speed Up Android Emulator to know clearly how.
If you created the AVD through AVD manager then you can change the RAM size in AVD Manager and device edit option.
If you created the AVD through command line, then you should start the AVD from command line will work,
emulator -memory 512 -avd gtv_avd
If everything else fails, it's good to try my option and download a HAXM installer.
It needs to be copied to HAXM installation folder and then started from command line (start CMD as an Administrator). After restarting computer HAXM will be installed. It perfectly worked for me as I was having problems with installing it on my laptop.
After all simply type sc query intelhaxm in your cmd in order to check whether HAXM is installed properly.
If you are running an Intel processor make sure the HAXM (Intel® Hardware Accelerated Execution Manager) installer is installed via SDK Manager by checking this option in SDK Manager. And then run the HAXM installer ext via the path below.
your_sdk_folder\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm.exe
Also check the RAM size allocated while doing HAX installation so it fits the RAM size of your emulator.
This video shows all the required steps which may help you to solve the problem.
This video will also help you if you face a problem after installing HAXM.
Download HAXM from the Intel site.
Install it.
And then run the AVD from AndroidStudio, menu -> Tools -> AVD. Choose x86.
It works!
