Android Studio Emulator "/dev/kvm Is Not Found"

Post a Comment
Couldn't use x86 emulators, AVD manager shows warning '/dev/kvm is not found' and telling me to edit BIOS security setting to enable VT-x.

Solution 1:

Re-installing HAXM resolved my problem Steps:

  1. Make sure SDK Manager -> Extras -> Intel x86 Emulator Accelerator (HAXM installer) is installed
  2. Navigate to <sdk>/extras/intel/Hardware_Accelerated_Execution_Manager/
  3. Run ./HAXM\ installation -u
  4. Run ./HAXM\ installation

Solution 2:

For MacOS users running Android Studio, when you get this error then try these steps to open up your privacy settings.

Thank you Apple for pushing me with your dumb*** app review rules from iOS to android development

Solution 3:

You just need to "start" the HAXM. You can do this following this steps:

  1. Open the cmd.
  2. Type sc query intelhaxm, click enter and check the STATE.
  3. If state is 1 STOPED, type sc start intelhaxm and click enter to start the HAXM.
  4. Check the STATE again and it should be 4 RUNNING now.
  5. Finally, you are now able to create and use your AVD using a x86 emulator.

Alternatively, when you want to stop the HAXM you should type sc stop intelhaxm.

Hope this helps y'all.

Solution 4:

I had a similar message in the emulators area in Android Studio 2.1.

My emulator for a certain API (think 21) worked initially fine and was fully accelerated, then installed a couple of other images (Nougat x86/64 etc) and suddenly started seeing /dev/kvm not found and NO emulator would boot up.

  • In My Case, re-installing HAXM sadly did not help, but rebooting my MAC did (go figure).

  • But, I also noted that if you have installed an emulator image but not the related SDK for the API (which makes sense), then you get a similar pop-up when starting the emulator, which makes you think it may be a HAXM / KVM issue, which its not.

Hope this helps someone.

Solution 5:

Just go to terminal and type 

sudo chown 777 -R /dev/kvm,

then type

sudo chmod 777 -R /dev/kvm.

And restart android studio

And that's it..

In some case it may happened that for every start of android studio you need to type this commands First and then start android studio.
