Android emulator and virtualbox cannot run at same time

Whenever I have Virtualbox running, I cannot start an Android emulator image (and vice versa). The error message in the AVD manager is

ioctl(KVM_CREATE_VM) failed: Device or resource busy
ko:failed to initialize KVM

How can I make both run at the same time?

That is a Ubuntu 64 bit, all involved software is of the latest released version.

Removing the kvm kernel modules (using 'sudo rmmod kvm_intel kvm') makes it possible to run the Virtualbox and the Android emulator at the same time but the performance of the Android emulator in such a setup is extremely bad. If possible it is better to shutdown the Virtualbox emulator and unload its driver (vboxdrv) by running 'sudo /etc/init.d/vboxdrv stop'. Google suggests this "solution" on its Android Emulator page in the section about Linux.

I got the same VirtualBox conflict. Solved it by using ABI different from "x86" (armeabi-v7a in my case)

I stopped the virtual machines I had running with VirtualBox. This made the error disappear.

I had the same problem on Ubuntu 13.10. Try to remove kvm and kvm_intel kernel modules.

To do this:

1. Stop all emulators.
2. Run command: 'sudo rmmod kvm_intel kvm'

Without these kernel modules Virtualbox and Android emulators can work at the same time.

BTW, I do not know why the modules are loaded.

There is finally a fix for this.

Follow these steps for macOS:

1. In Android Studio Go to Tools -> Android -> SDK Manager

2. Confirm you have the latest version of Intel Emulator Accelerator HAXM installed (v6.1.1) .

3. Go to the extras directory of the Android SDK location displayed in the preferences. On MacOS you can do this:

   open ~/Library/Android/sdk/extras

4. Install the HAXM packing by opening IntelHAXM_6.1.1.dmg, then opening IntelHAXM_6.1.1.mpkg in the mounted folder, and following the installer instructions.

Follow these steps for Windows:

1. In Android Studio Go to Tools -> Android -> SDK Manager

2. Confirm you have the latest version of Intel Emulator Accelerator HAXM installed (v6.1.1) .

3. Go to the extras directory of the Android SDK location displayed in the preferences. Something like:

   C:\Users\<username>\AppData\Local\Android\sdk\extras

4. In that directory is some kind of file like intelhaxm-android.exe. Run it.
