Answer 1

Make sure you don't have any virtual machines running. In my case, I had genymotion running which was causing this error. when i kill genymotion's Process and kill all Oracle VM VirtualBox related process then it work by wangshiming don't thankyou me

This kept failing until I changed it to [x] Use Host GPU as shown in pic.

Answer 3

1. Stop GENYMOTION (open VirtualBox instance if any instance is running, stop it).
2. Open AndroidStudio -> Run AVD Manager-> run AndroidStudio virtual device.

Latest Android Emulators are not able to run in parallel with GENYMOTION

Answer 4

For me the answer was to set Enable keyboard input to true under the advanced settings of the virtual device.

This was the first option I changed on the device, so it is possible that the act of changed an option fixes the error as well based on the wide array of answers above.

Note: I've confirmed previously that no VM's are running.

Answer 5

If you are running Docker you would have to take the virtual machine down

docker-machine stop default

This assumes your docker machine is called default. If you want to check the name use docker-machine ls

A simpler solution; open virtuabox and stop the vm :-)

I think it must be a variety of reasons cause this failure. In my case, since I installed the Google input method software, "Failed to sync vcpu reg" appeared. This was the one and only change before normal working. So, after uninstall the Google Input software, it was recovered.just a little reference, although I can't believe this solution for long time either.
