The first time I ran Genymotion virtual device, it had worked. But when I tried running it today, I got this error message
What may have changed from the last time I used it? Will be grateful for any solutions that I can get. Thanks.
My Device Info:
Dell XPS L502X
Sandy Bridge motherboard
Intel Core i5-2410M #2.30 GHz
Windows 7 Professional 64-bit
You need to turn virtualization on.
Reboot the notebook.
Instantly press F10 to enter BIOS settings (or F2 depending on your PC)
Check the settings and look for Intel Virtualization Technology (Aliases: Intel VT-x).
Turn it on then save and exit. You could use F10 to save and exit.
This will enable you to use virtualization and enable VirtualBox. Therefore your emulator will hopefully work.
I've solved my problem just turning off the Hyper-V on Windows Features.
Another way to receive this message is because you are running another application that use VT-x like the Android Emulator from Android Studio. If you open Virtualbox and try to start the VM you will get this error message. Solution: Close the other emulator and try again.
For me the following worked:
Disable/uncheck "Enable VT-x/AMD-v" in the virtual device's Settings-> System -> Acceleration
Execute the following command in cmd opened as administrator to disable hyper-v and then reboot the machine:
bcdedit /set hypervisorlaunchtype off
I don't know why disabling hyper-v from system preferences doesn't work for me, only the command works for me. Also I had to close Docker first to execute the command.
Solution for windows 10: Control Panel → Programs → Turn Windows components on or off.
Uncheck the Hyper-V option and click OK.
in ubuntu
1-Reboot the notebook.
2-enter BIOS (press F10 or F2 )
3-Check enable Intel Virtualization Technology and save and exit.
I've also seen this exact same error dialog (for the first time ever) today after upgrading to the latest versions of both VirtualBox and GenyMotion. Nothing else on my system has changed. It's not the best answer in the world, but after trying a few other suggestions I came across, I found that simply cancelling the dialog and restarting the virtual Genymotion device (either via Android Studio or via the Genymotion console) resolved the problem.
Fix it in Virtualbox directly
Open VirtualBox
If you find a similarly named device "Inaccessible" or any other state than "switched off", stop it or remove it.
Start the device from Genymotion
Feel Happy :)
i just decreased the amount of base memory used by the machine in virtualbox manager settings > System > Base Memory and it worked.
In VirtualBox settings > System disable I/O, EFI, UTC and AMD-V.
And Settings > Network > Promiscuous Mode modify in all.
I've seen this exact same error dialog on the first install. I changed my BIOS settings and it worked but after a month the same error occurred.
My solution:
Open VirtualBox Manager
Settings > Network > Promiscuous Mode
Change from "deny" to "allow"
I had to deactivate 'Memory Integrity' of Windows 10 (1803) 'Core Isolation' Feature of Windows Defender. It is deactivated by default, and for some odd reason I had forgotten I had switched it on recently.
I also checked that in VirtualBox -> Your virtual machine -> Settings -> System -> Acceleration -> 'Enable VT-x/AMD-v' and 'Enable nested paging' are activated, Hyper-V is not installed and virtualization is turned on in BIOS.
There is an explaining article on HowToGeek explaining that aformentioned Memory integrity feature:
https://www.howtogeek.com/357757/what-are-core-isolation-and-memory-integrity-in-windows-10/
I have solved this issue not just by enabling VT-x but also by enabling VT-d (Virtualization Technology for directed I/O) in BIOS
I fixed it in VirtualBox:
Setting > System > Disable checkbox "Nested Paging"
One more correct answer is that recent versions of Genymotion support only 64bit CPU and that will cause the same error.
For me the solution was to close another emulator which was open.
None of the solution worked for me. This is what solved the issue:
Turn on Hyper-V in Windows Features.
Restart PC.
Turn off Hyper-V in Windows Features.
Restart PC.
Boom!
I Had The Same Problem And I Solve It By Turning Off The Hyper -v In Windows Programs And Features. Now I Can Start Any Virtual Device From Both Android Studio And Genymotion.

I have windows 10 Home and AMD ryzen 5 processor.
I'm using android studio 4.0 canary 7 (I also tried the latest stable version with the same error).
I'm following the official tutorial to enable the Android Emulator for AMD Processors here..
https://androidstudio.googleblog.com/2019/12/emulator-29211-and-amd-hypervisor-12-to.html
This is relatively new and I created an issue for them but wanted to see if someone might help with this or had this problem before. So everything looks good until the step to install gvm as administrator by going to the directory (Android_Emulator_HyperVisor_Driver) and running silent_install.bat. For some reason it is failing to run the service and I get the following error
[SC] ControlService FAILED 1062:
The service has not been started.
[SC] DeleteService SUCCESS
[SC] StartService FAILED with error 4294967201.
Hypervisor platform is disabled (It should according to this latest tutorial as this is different than how it was last year). Any feedback or suggestions are appreciated.
If you tried everything (turning windows features off, enabling svm in bios..etc) and still didn't work, type bcdedit in the command prompt, and press ENTER. If you see an entry for hypervisorlaunchtype set to Auto, Hyper-V is still enabled. You can try setting the launch type to Off by running the command below.
bcdedit /set hypervisorlaunchtype off
That's the only thing that worked for me after trying literally everything.
If You are using AMD Ryzen Just go to bios setting check for SVM Mode if it is Disabled then Enable it .. Emulator work perfectly..Below Link show where to enable SVM Mode in Aorus Gigabyte Motherboard BIOS..
https://www.youtube.com/watch?v=46DfLwX5AFQ
also Disable hyper-v in windows feature.. sample below
https://github.com/google/android-emulator-hypervisor-driver-for-amd-processors/wiki/Is-Hyper-V-really-disabled%3F
After this emulator will works like a charm...
Go to BIOS setting of your laptop/PC, and enable the SVM setting and save it. This should work. This issue is because Virtualization on the PC is disabled once it is enabled it works. Please let me know if it doesn't work.
NOTE :
BIOS - As your PC’s most important startup program, BIOS, or Basic Input/Output System, is the built-in core processor software responsible for booting up your system.
Restart your machine and press the hotkey, your BIOS setting will be opened.
These are some brands hotkey, might be useful.
Acer: F2 or DEL
ASUS: F2 for all PCs, F2 or DEL for motherboards
Dell: F2 or F12
HP: ESC or F10
Lenovo: F2 or Fn + F2
Lenovo (Desktops): F1
Lenovo (ThinkPads): Enter + F1.
MSI: DEL for motherboards and PCs
Microsoft Surface Tablets: Press and hold volume up button.
Origin PC: F2
Samsung: F2
Sony: F1, F2, or F3
Toshiba: F2
If you are using Avast antivirus (or AVG), this can be the cause of this problem.
So things to do to fix this:
Activate Virtualization in bios
Deactivate Hyper-v and hypervisor platform in "activate/desactivate windows function"
& run powershell as admin and run the following command: Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V
In Avast Antivirus. In settings click Troubleshoot on the left side of the screen, uncheck the box next to Enable hardware assisted virtualization, then click OK to confirm and restart your computer
I've got the solution from https://github.com/google/android-emulator-hypervisor-driver-for-amd-processors/issues/10#issuecomment-715423881.
I found the answer after long time. I had to enable Virtualization on my machine.
I have tried everything that's written here, with no success.
For me an option in BIOS (AMD V(TM), which is actually the same (or maybe almost the same) as SVM or SVM Mode) was ON already. And I didn't try to touch it at all. So I was going to write to support already. And in the process of gathering information for that I have turned that option off in BIOS. And then ON again (with restarts on every step ofc). Then I have discovered, that the folder with silent_install.bat has dissapeared. So I went to Android Studio and discovered that Emulator just works.
So, If you had tried everything, try to just turn off virtualization in BIOS and after restart turn it back On.
I'm just a hobbyist so I have no idea why this works but if you install NoxPlayer (Android emulator), Android Studio emulator works perfectly.
I'm new to Android, i have downloaded Android studio 2.1.2 and SDK. After reading references from google i wrote HelloWorld application, which can run on my phone.
But due to certain reasons i have to run AVD in AndroidStudio to execute my application. but is shows following error
Intel HAXM is required to run this AVD. /dev/kvm is not found.
Enable VT-x in your BIOS security settings, ensure that your Linux
distro has working KVM module.
Following things i have done so far.
Installation of HAXM manually.
Enabled Virtualization from BIOS.
Some of the references on stackoverflow suggested to uncheck Hyper-V
option in Turn on off windows feature. (i have found nothing like
hyper-V there)
I'm running Windows 7
I'm just stuck here. any help would be highly appreciated.
EDIT:
I have read that Dell Optiplex760 does not support virtualization.
but i can run VirtualBox on my machine. moreover i have seen Virtualization option in BIOS. Also Secureable shows that my system supports Virtualization.
First, reboot you system, press the hot key to enter the BIOS.
enter BIOS
Second, enable the Inter(R) Virtualization Technology and save.
enable VT
Third, start up your computer, enter CMD, input "sc query intelhaxm" to check the state.
CMD command
Forth, start up your AVD, if error happens like that. Go next step.
error tips
Finally, go into your SDK directory, reintall the intellhaxm-android.exe again, then launch the AVD Monitor.
reinstall haxm
I hope it works.
I have attempted to run Genymotion Android emulator by following the User Guide, but am getting the following error:
Unable to start the virtual device.
VirtualBox cannot start the virtual device.
To find out the cause of the problem, start the virtual device from VirtualBox.
For more information, check the log files. Please refer to: https://www.genymotion.com/#!/support?chapter=collapse-logs#faq
Can anyone suggest how I can resolve this?
Enter to BIOS and look for an option named "Intel Virtualization Technology", "Intel VT-x", "Virtualization Extensions", "Vanderpool" or something similar. Enable the option and select “Save and Exit” or the equivalent feature to save your settings changes and reboot your computer.
How to Enable Intel VT-x in Your Computer’s BIOS or UEFI Firmware
My suggestion is to forget Genymotion and VirtualBoxas they are very bad. Download Droid4x it is very easy to test apps with.
One thing to do when you download and install it, is to go to Settings -> Developer Tool Debuging and turn it on.
Good luck.
Change the virtualBox to 4.3.12
Delete the virtualBox and download from https://www.virtualbox.org/wiki/Download_Old_Builds_4_3_pre24
choose 4.3.12
my computer is windows7 and it works.
Really old question but to solve it you can try to download VirtualBox latest version
It solved the problem for me already twice. First time when I first downloaded GenyMotion that came with an old incompatible version of VirtualBox. After a couple of months the problem appeared in GenyMotion again and a VirtualBox upgrade solved it again.
This is because either you have changed the Virtualbox host-only settings or have completely deleted the Virtualbox host-only in the network connection window.
To fix this, just uninstall the virtualbox and genymotion once and install Virtualbox and Virtualbox sdk first, and then install genymotion.
I faced with this issue and updated the virtual box latest version and everything works now.
Goto Network Settings >>
Select Adapter settings >>
open VirtualBox properties >>
Enable Virtualbox networking Driver >>
Okay.
I tried to make my android emulator work faster and as the title says, I can't get to install HAXM driver on my laptop. I've looked everywhere and did everything people suggested on other pages. Intel Virtualization Technology in bios is enabled. Updated Eclipse tools etc. Downloaded driver directly, instead of throguh Eclipse manager. I even tried to disable Hyper-V in Windows functions but it's not there.
I still get the following error when trying to install the driver:
(Can't post images so I will just rewrite it)
"This computer meets the requirements for HAXM, but Intel Virtualization Technology (VT-x) is not turned on. HAXM can be installed, but will not work until VT-x is enabled."
As I said before, it is ENABLED in bios so I have no idea what's the problem.
I would appreciate any help. Thanks.
Some antivirus prevent Haxm installation. In my case -- Avast : settings tab -> troubleshooting -> uncheck "enable hardware-assisted virtualization" Solved the problem
A step-by-step tutorial can be found here
Although this is an old question, but I've still encounter it recently.
This is what worked for me on my i7-3770 3.40GHz, Z77 extreme motherboard running Windows 10.
In Windows, disable Hyper-V:
Open up a PowerShell or CMD session as Administrator.
Type the following command:
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V-All
Windows will ask you to restart.
In the bios:
Disable >>> Intel Virtualization Technology, vt-d
Save the bios settings and allow it to restart and boot into Windows.
Shutdown the computer (I've tried just restarting and it didn't work)
Power up the computer, go into the bios and re-enable the above disabled settings.
Save, restart.
Download the Intel Utility to check.
You should now see it been supported:
If it still doesn't work, try re-enabling Hyper-V first then following the steps above.
Hope my answer helps someone who ends up on this page for the question
I had just updated my BIOS and found that emulator on Android Studio was not starting mentioning "VT-x not enabled". When I checked task manager it showed Virtualization is Disabled
On entering BIOS found that Virtualization showed enabled. I exited and googled up in vain.
How I got rid of it:
I entered BIOS setup once again, this time I disabled it and re enabled. Saved and exited.
When I again checked in Task Manager, "Virtualization showed as enabled"
I made sure emulator is also running as I am typing this answer
had the same problem with my elitebook-i7 while running windows 10 pro. just like #Sajkor non of the method worked that's why am advising you try this method out:
Search program and features and open
open "turn windows features on or off"
under hyper-v, expand hyper-v platform an disable Hyper-v hypervisor
Also disable virtual machine platform
save and restart the pc
hope it helps, see the image if you are lost

do you have any other software installed on your PC, that may prevent HAXM to use VT-x ?
Maybe you've got some other SDKs/emulators installed that would come with a virtualization service ?
Also, what's your laptop ? Sometime BIOS may be buggy and to really enable VT-x, you may need to disable it, shutdown and boot your PC again, enable VT-x, shutdown and boot again.
I'm developing a suite of mobile apps - specifically Windows Store/Mobile 8 and Android.
Having installed VS2012 and then Monodroid, I was then able to start x86 Android images in the emulator and take advantage of the Intel HAXM acceleration (emulator output confirms HAXM working) to make the VM buttery-smooth.
I then installed the Windows Phone 8 SDK - which enables the Hyper V role - and now the emulator says it can't find HAXM. I then uninstalled and tried to reinstall HAXM, but now it won't - saying that my processor doesn't support it.
The VT-x extensions are still enabled in the BIOS - so I'm thinking that Hyper-V has blocked the Intel HAXM from working.
Of course it's not a killer - but a non-accelerated Android image is considerably slower than one with HAXM enabled - anybody else encountered this problem? Googling isn't bringing up anything obvious...
Update (30th Nov 2012)
Per #alexw's suggestion I tried stopping & disabling Hyper-V; with a restart. It still doesn't work.
I realise the next step is probably to the Windows Phone SDK (and remove Hyper-V) and then try again - to confirm that it really is the presence of Hyper-V. At the moment this is less than convenient - but I'll try and do it soon and update.
The best thing you can do to get HAXM detect VT again, is turning the whole Hyper-V "Feature" off. Open "Control Panel -> "Programs" -> "Turn Windows features on or off" (under "Programs and Features") and locate "Hyper-V", uncheck, reboot.
Looks like Hyper-V and HAXM are mutually exclusive, which is kind of a nuisance, because you even need to reboot twice to enable or disable either feature.
I was in your same case that needed to support Hyper-V and Intel HAXM. Disabling and enabling the feature and then restarting was overkill so I found an alternative solution.
You can create 2 boot entries, one for Windows with the regular configuration of Hyper-V enabled and another one with Hyper-V disabled. I logged in with the second one (Hyper-V disabled) and I was able to install Intel HAXM.
To accomplish this you need:
Open a command prompt as Administrator
Enter the command: bcdedit /copy {current} /d "Windows 8 - No Hyper-V"
This will output an id with the format {GUID} that you need to copy it to use it in the next command.
Enter the command: bcdedit /set { copied GUID of step 3 } hypervisorlaunchtype off
More details in this post.
I had a similar problem installing HAXM on Windows 8. I did the following with no effect:
Disabled hypervisor using the instructions here (http://blogs.msdn.com/b/virtual_pc_guy/archive/2008/04/14/creating-a-no-hypervisor-boot-entry.aspx)
Double checked that processor supported VT-x and was enabled in BIOS (BIOS said "supported", but there was no option to turn it on
Verified that all Hyper-V services in control panel were stopped (and never automatically started)
Performed a complete shutdown and a cold boot up.
However, I tried installing VirtualBox after the above actions (VirtualBox installed fine) and created a new VM. Running the VM caused my machine to blue screen, but after the reboot HAXM installed fine. Perhaps running VirtualBox flips some sort of flag at the OS level to allow HAXM to install.
I was also running AVAST at that time, and according this (Running the new Intel emulator for Android), that may cause a problem. However, I didn't have to disable AVAST to get HAXM installed.
You could try stopping the Hyper-V service when not needed and re-enabling it when you want to work on a WP8 project. It's a pain but the performance improvement offered by HAXM is immense.
Open services.msc, find the hvboot service (Hyper-V) and stop it. If this doesn't help you may need to disable the service and restart your pc.
I had the same problem. After a long search I found the answer. In my case, I had installed Avast Antivirus, first uninstall avast, reboot your PC, install Haxm, reboot. you can install again antivirus.
