my pc has 8 gb ram, intel i5-4rth gen , 2 gb nividia card.
win 7
my emulator of API 21 is very slow and laggy even after installing intel HAXM manually.
I have done everything that has been discussed here. please suggest me something.
In my case the problem was Avast's "Hardware assisted Virtualization". When I disabled it by going to Avast>Settings>Troubleshooting>Uncheck "Enable hardware-assisted virtualization" and rebooted the PC emulator became super fast and responsive.
Uncheck "Enable hardware-assisted virtualization" from Avast>Settings>Troubleshooting
Reason: Only one software can use VT-x at a time. This is the reason why we have to disable Hyper-V before using HAXM.
If you are using another anti-virus or some software that is using Hardware virtualization feature, try disabling it.
I`m have same issue (i5, integrated video, W10x64), and today was found a way to fix:
add "-gpu guest" parameter to emulator.exe
Unfortunately, it should be started from a .bat file or command prompt.
Whole launch string look like
emulator #avd_name -accel on -gpu guest
Hope this helps
After the download from the SDK manager you have to launch the IntelHAXM.exe that you can find inside the Android SDK manager folder, precisely in
extras/intel/Hardware_Accelerated_Execution_Manager
to run the emulator in the new Android Develop Studio, I need to turn on the virtualization support (VT-x) on my guest windows 7 running in KVM, which in turn is on RHEL6.
Google shows we need vmx & vme in the guest processor definition, which I have them as 'require' from dumpxml. But in Android Develop Studio in my guest win7, it still complains about missing virtualization support.
Cannot launch AVD in emulator.
Output:
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 then download 'haxm-windows_r05' and run 'intelhaxm.exe' to install it, with error:
VT not supported
This computer does not support Intel Virtualization Technology (VT-x). HAXM cannot be installed.
Please refer to the Intel HAXM documentation for more information.
In summary, my guest (windows 7) on KVM (running on RHEL 6) can not turn on Intel Virtualization Technology (VT-x).
Thanks for any help

Unfortunately, RHEL6 lacks support for Nested Virtualization. RHEL7 does but it's still very premature and new changes keep getting added. Your best bet is to install the current upstream kernel. To enable Nested Virtualization, load kvm_intel with "modprobe kvm_intel nested=1".
And ofcourse, you need to advertise vmx in your cpu definition.
The error says that your system supports HAXM but Intel Virtualization Technology is not turned on. But I checked that Virtualization is enabled. What to do now?
Go into your BIOS setup and enable VT-x.
I was unable to get it installed and ended up installing the GenyMotion Android Emulator. It worked and is fast.
This is a really good video showing how to enable virtualization in Bios. I'm not sure why, but if you're using the Intel Processor Identification Utility, it says that virtualization is enabled, but that really only indicates that your computer supports virtualization, not that it's actually enabled. Once you've enabled VT-x in the Bios, you should be able to install HAXM and run your emulator much more quickly!
I have an issue with my HAXM installation. Here is the thing. I got this error every single time I tried to install HAXM for my computer:
Problem is, that my computer supports Virtualization Technology (see pic below). Any idea how to fix this issue?
Just follows these steps:
Go to Control Panel → Program and Feature.
Click on Turn Window Features on and off. A window opens.
Uncheck Hyper-V and Windows Hypervisor Platform options and restart your system.
Now, you can Start HAXM installation without any error.
Hello and welcome to the 3rd installment of the infamous Android Emulator on Windows saga. Despite the combined 3 trillion dollar market cap of Microsoft and Google, this remains to be a problem harder than going to the moon.
Below is the somewhat comprehensive list for Windows (so far as of circa 11/2022)
First make sure you have the latest version of Windows. As of writing, this is Windows 11 22H2 with all updates installed. If you have an older version of Windows, you'll have to try each one of the below, with possibly different combinations. Otherwise follow from the top until your issue is solved. It is ordered from the easiest/most likely culprit on a decent Windows machine, to the most unlikely cause.
Note that if you're doing below on a corporate machine, some of the below actions may be blocked by your admin, and/or flag your machine as suspicious activity as some actions intentionally turns off some security features. Depending on your situation, you may want to give a heads-up to your IT/security team.
If your Windows device has Bitlocker enabled on your boot drive contact your IT admin first. Messing with virtualization and boot configuration may trigger bitlocker prompts upon reboot. If you're working from home,this may mean taking your laptop to the office to get it unlocked by IT, as Windows may refuse to boot without unlocking BitLocker.
To find what is blocking the emulator launch, the surefire way is to open a terminal (cmd or powershell) and launch to from there as below.
First kill any existing emulator.exe instances, adb.exe instances, java.exe instances, qemu instances, android studio instances. Check in task manager to be sure.
The adb relaunches itself so its ok be running. But make sure android studio is not running. It seems to lock files/cache and not flush emulator configs, that may crash the emulator at launch, without any useful logs.
in a terminal
cd your_sdk_location\emulator
emulator.exe -list-avds
this will list what AVDs you have. Find the one you want
emulator.exe -avd your_avd_name -verbose
This will have a long log, and will have some information on what the failure is. If you see a VM heap size being outside of limits, it may say that it it automatically set to lowest or highest value. This is a lie. Open emulator settings and set it to within the limits manually, usually 550MB works. Launch android studio and edit the emulator instance to be within this limit, then close android studio, then wait about 30 seconds before attempting to launch the emulator. For all attempts of launching the emulator below, do not rely on android studio, launch from command line instead.
Note that the emulator editor UI in android studio can corrupt the config at times. If this happens, I don't know where this is stored, so you may have to delete and re-create the AVD. If this doesn't work, do not change and configs during AVD creation, then launch it from command line.
If the emulator doesn't launch, no useful failure logs, yet the emulator.exe exits after a few minutes, you may have android studio running. Exit/Kill Android studio, wait a minute or so and try again. If still fails, reboot.
Have an Antivirus (other than Microsoft Defender)?
Disable it
Reboot and try to launch the emulator
Disable Hypervisor Boot
open an admin terminal (cmd or powershell)
run bcdedit /set hypervisorlaunchtype off
try to launch the emulator. If still broken, try rebooting.
If your failure is due to install of HAXM/AMD hypervisor driver failing
run systeminfo in a terminal
at the end under Hyper-V Requirements: if it says A hypervisor has been detected this means emulator cannot launch virtualization.
Open Start > Windows Security > Device Security > Core isolation
turn off Core Isolation (previously known as Memory Integrity/Isolated User Mode)
Open Turn Windows features on or off and disable
Hyper-V Platform
Hyper-V Management Tools
Windows Hypervisor Platform
You can enable them after HAXM/AMD Driver install
on an admin prompt run bcdedit /set hypervisorlaunchtype off
reboot
try to launch the emulator
Check BIOS
go into BIOS/UEFI setup and look for settings like
VT-x
VT-d
Virtualization Technology
Hardware Virtualization
Make sure these settings are enabled
try to launch the emulator
Uninstall Docker Desktop
Some users have reported that uninstalling Docker Desktop fixed their issue.
It is unclear as to why docker desktop interferes with haxm installation. The reason is probably that it supports running docker images via a Hyper-V backend, and disabling this feature does not remove the hypervisor completely.
Go to Settings -> Add or remove programs, and uninstall docker desktop
reboot
try to launch the emulator
Nothing works
You shouldn't get here, since Android emulator can now run alongside with Hyper-V if you have 'Windows Hypervisor Platform' enabled.
If nothing above works, as a last resort you can try running Android in a Hyper-V VM and get ADB to connect to it. (Not a solution, but a workaround)
You can also run android using a third-party emulator like Genimotion.

Debug on a physical device
You can also use Wifi debugging via adb pair ip:port and adb connect ip:port commands.
or get a Macbook
After few days of googling I found, that problem was caused by hyperthreading (or hyper - v). I decided to edit my boot.ini file with option to start up windows with hyperthreading turned off.
I followed this tutorial and now everything works perfect
chances are that you have windows 8 with hyper-v installed? if yes remove hyper-v and your problem goes away!
First of all make sure you enabled Virtualization Technology in your BIOS. After restarting your computer press F1-F12 on your keyboard and find this option.
Make sure you disabled Hyper-V in your Windows 7/Windows 8. You can turn it off in Control Panel -> Programs -> Windows functions
You can try to disable your antivirus program for the whole installation process. Remember to restore all antivirus services after installing HAXM.
Some people recommend cold boot which is:
Disabling Virtualization in your BIOS
Restart computer and turn it off
Enable VT in your BIOS
Restart computer, turn it off
It's likely that now might be allowed to install HAXM
Unfortunately this step didn't work for me
Last but not least: try this workaround patch released by Intel.
http://software.intel.com/en-us/blogs/2013/04/25/workaround-patch-for-haxm-installation-error-failed-to-configure-driver-unknown
All you have to do is to download the package, unzip it, put it together with HAXM installator file and run .cmd file included in the package - remember, start it as an Administrator.
I had a lot of problems with installing HAXM and only the last step helped me.
In the "Turn Windows features on or off" window, un-check Hyper-V and also ensure that Windows Hypervisor Platform is unchecked. Windows Hypervisor Platform being enabled can also block the installation of the Intel HaxM
Maybe VT-X is not enabled in your BIOS.
See Intel HAXM documentation here: http://software.intel.com/en-us/articles/installation-instructions-for-intel-hardware-accelerated-execution-manager-windows
Intel VT-x not enabled
In some cases, Intel VT-x may be disabled in the system BIOS and must
be enabled within the BIOS setup utility. To access the BIOS setup
utility, a key must be pressed during the computer’s boot sequence.
This key is dependent on which BIOS is used but it is typically the
F2, Delete, or Esc key. Within the BIOS setup utility, Intel VT may be
identified by the terms "VT", "Virtualization Technology", or "VT-d."
Make sure to enable all of the Virtualization features.
Anti-virus software may interfere with the HAXM installation.
After trying to figure out what went wrong for a few hours I found a strange solution - uninstalling my anti-virus software , installing HAXM (which worked) and then re-installing the anti-virus software (Avast in my case but it could happen with other anti-virus programs as well.
The full check I went through to get this running is:
Check the 'Virtualization' and vt-X feature in the BIOS.
Verifying Hyper-V is not installed.
Checking weather vt-X is enabled in windows with the Intel tool and MS tool (mentioned in previous posts in this thread).
Disabling the anti-virus which didn't help.
Uninstalling the anti-virus (which solved the problem for me).
In Windows 10, Windows Defender has a feature of core isolation which uses virtualisation technology that will also interupt in working of HAXM. Disable it and try again. In my case disabling it solved my issue.
If you have an AMD Ryzen processor in your computer you need the following setup requirements to be in place:
AMD Processor - Recommended: AMD® Ryzen™ processors
Android Studio 3.2 Beta or higher - download via Android Studio
Preview page
Android Emulator v27.3.8+ - download via Android Studio SDK Manager
x86 Android Virtual Device (AVD) - Create AVD
Windows 10 with April 2018 Update
Enable via Windows Features: "Windows Hypervisor Platform"
Note:There is Hyper-V features... You should enable Windows Hypervisor Platform not Hyper-V.
Windows Hypervisor Platform is at the bottom
After conditions done avd x86 work without haxm install
Reference
In many cases some antivirus also start HyperV with window start and does not allow HAXM to install.
I faced this issue because of AVAST antivirus.
So I uninstalled AVAST, then HAXM installed properly after restart.
Then I re-installed AVAST.
So its just a check while installing as now even with AVAST installed back, HAXM works properly with virtual box and android emulators.
After I installed Visual Studio 2013 Update 2, Visual Studio notified me about a Windows Phone emulator update, which I installed (it was really a new component, not an update). It turned out this enabled Hyper-V, which broke HAXM.
The solution was to uninstall the emulator from Programs and Features and to turn off Hyper-V from Windows Features (search for "Windows Features" and click "Turn Windows features on or off").
If you dont find Hyper-V option in control panel as said in other responses here, try entering BIOS setup (restarting and pressing F-12 or ESC or other depending on your PC) and enabling Virtualization, located probably in CPU options.
I'm running Windows 10 and had this problem after I changed my SSD, I fixed it by disabling the VT support on Bios. I got a different error after I ran the installer. I rebooted and enabled VT support again and voila, working now.
If any of the answers doesn't work just remove Android Emulator and reinstall it again. and after that try installing Intel Haxm.
If none of the answers worked out for you, try this,
Hyper-V might not be disabled
If you have windows 10 features such as Device Guard and Credential Guard is enabled, it can prevent Hyper-V from being completely disabled.
The Device Guard and Credential Guard hardware readiness tool released by Microsoft can disable the said Windows 10 features along with Hyper-V:
Download it here, https://www.microsoft.com/en-us/download/details.aspx?id=53337
Download the latest version of the Device Guard and Credential Guard hardware readiness tool.
Unzip
Open the Command Prompt using Run as administrator
#powershell -ExecutionPolicy RemoteSigned -Command "X:\path\to\dgreadiness_v3.6\DG_Readiness_Tool_v3.6.ps1 -Disable"
Reboot.
I already tried all of the possible solutions on stackoverflow and didn't work
What I tried:
Disable Hyper-V in windows feature
Disable Hyper-V with command
Disable Device Guard
etc etc
Above solution still give me information about Hyper-V in System Information and the HAXM still failed to install.
But finally I found the solution, you have to disable Hyper-V from System Configuration:
Open System Configuration
Click Service tab
Uncheck all of Hyper-V related
Check System Information then Hyper-V is off now
Fix the error. follow the following steps
Turn off Hyper-V and Windows Hypervisor Platform
Goto RegEdit "Windows Defender is blocking HAXM."
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard
Set the key EnableVirtualizationBasedSecurity to '0'
if Key is not available create a key
Re-boot the machine
Install the intelhaxm-android.exe
