Android emulator and virtualbox cannot run at same time

Question

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.

My backend required for the app to have data runs on VirtualBox (Vagrant), so that's not a great option :P – Richard de Wit Nov 20 '15 at 11:46

This solution #@%!'s due to the fact that i need to run both at the same time .. my HTTPD service is in Virtual Box, while my App is in Android .. /me sighs. Guess, it's time to fire up the Dev Server again. – E Net Arch Feb 01 '17 at 19:15

Another option may be to use Docker instead of VirtualBox in conjunction with the Android emulator. – Matt Welke Feb 06 '18 at 22:59

Or run Vagrant with KVM. – Michael Hampton Nov 07 '18 at 20:17

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

Presumably the emulator will run slowly this way, but it is an option. – ToolmakerSteve Dec 01 '16 at 00:55
In my case I also need the VirtualBox VM to run (for RDP), so this was a really good advice. – Csaba Toth Dec 01 '16 at 05:39
This answer is a bit cryptic. Could you elaborate? – rudolfbyker Jan 02 '17 at 09:05

@rudolfbyker, what the answer says is that emulators that run with CPU/ABI x86/x86_64 is a lot faster, but uses the same KVM (Kernel-based Virtual Machine) as VitualBox. Creating an emulator with another CPU, like arm64, will not conflict with VirtualBox, but emulator is _a_ _lot_ slower. – jayeffkay Jan 18 '17 at 13:24
Could you explain, how can we implement it? Thanks. – Mukundhan Apr 10 '19 at 13:15

This worked for me in Fedora 20. With bigger displays, more RAM and Gnome 3 workspaces, it's easy to forget you're running another machine somewhere in the background. `killall virtualbox` should do it. – Ray Foss Jan 18 '15 at 04:11
Works but not the best solution. You can have them both (see Stanislav's answer) – MonoThreaded Feb 03 '15 at 08:22
I had this issue with Ubuntu 16 while using docker machine and virtual box drivers. stopping the vms with `docker-machine stop machine-name` resolved the issue as suggested in this asnwer – Benjamin Slabbert Jan 03 '18 at 09:05
Turns out just shutting down VirtualBox GUI and VMs won't do the trick. In my case I had several virtualbox processes still running: VBoxSVC, VBoxNetDHCP, VBoxXPCCOMIPCD. Killing them in top/htop solved the issue. – Babken Vardanyan Mar 16 '18 at 06:01

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

To do this:

Stop all emulators.
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.

A word of warning: while this does work, removing the KVM kernel modules will cause a substantial decrease in performance with the Intel Android image, since you lose the CPU's hardware acceleration support without the kernel modules. – JustJohn Aug 10 '13 at 18:04

@Tajchert: to revert: 'sudo modprobe kvm_intel kvm' – Splitlocked Apr 15 '16 at 08:31

There is finally a fix for this.

Follow these steps for macOS:

In Android Studio Go to Tools -> Android -> SDK Manager
Confirm you have the latest version of Intel Emulator Accelerator HAXM installed (v6.1.1) .
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
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:

In Android Studio Go to Tools -> Android -> SDK Manager
Confirm you have the latest version of Intel Emulator Accelerator HAXM installed (v6.1.1) .
Go to the extras directory of the Android SDK location displayed in the preferences. Something like:

C:\Users\<username>\AppData\Local\Android\sdk\extras
In that directory is some kind of file like intelhaxm-android.exe. Run it.

I finally made this problem obsolete by using Genymotion instead of the standard Android emulator. Besides not having this conflict, it is several times faster than the normal emulator.

This probably disappeared because genymotion didn't use KVM. Neither stable *(because at some point they gonna start using it)*, nor performant solution. – Hi-Angel Oct 17 '16 at 08:16

For those who are developing on Linux and are stuck with a host of back-end systems running inside virtualbox, a simple solution is simply to create a virtualbox X86 Android VM and expose the 5555 port on the NAT interface tunnelled from localhost through PAT. No need for slow arm AVD, no need for libvirt/vagrant let alone killing kvm!

Then let adb know about it

$ adb tcpip 5555
restarting in TCP mode port: 5555
$ adb connect 127.0.0.1
connected to 127.0.0.1:5555
$ adb devices
List of devices attached adb server
* daemon started successfully
emulator-5554   device

Then, pressing run or debug, in Android Studio will deploy and execute on that VM. You have complete control under Android Studio debugger.

Connecting to "VirtWifi" in the android virtual machine (inside VirtualBox) solved the problem! – Mohit Atray Jul 17 '21 at 20:42
Also consider using the terminal emulator in the Android X86 VBox to edit /etc/hosts, or even install an SSHD server (user space) app on the VM. – Alain Pannetier Jul 18 '21 at 14:10
By far the best option – Kanchu Aug 11 '22 at 04:41

Though it's a workaround either, but definitely better than disabling KVM as everyone suggesting.

Just run the virtualbox guest in KVM instead. For example (kvm here is just a script running a qemu-system-x86_64 -enable-kvm):

kvm Win7.vdi -boot c -m 2G -vga qxl

@MikeSchem yeah, unfortunately configuring a network in KVM/QEMU is a big deal.

In some cases, we need to keep virtualbox machines up and running therefore let all the virtualbox machines keep running, switch to physical mobile device to test your application instead of emulator.

you can use expo if you are doing with react-native or your real android/ios device.

This might be out of topic, due to the fact that OP requested VirtualBox + KVM in the same time, but still, it might be the workaround: I was looking for a way to launch Windows 7 and AVD on Ubuntu 18.10 x64. Turning off KVM is not an option due to the fact that performance of AVD is critical to me. I have installed Windows 7 via Virtual Machine Manager (virt-manager package) and now both the AVD and Windows 7 are hardware accelerated.

Here is how solved this issue, using vagrant and it's two plugins 'libvirt' and 'mutate':

Open terminal and set environment variables:

 export VAGRANT_DEFAULT_PROVIDER=libvirt
 export VAGRANT_HOME=/home/directoryToStoreVagrant/
 VBoxManage list vms

Now copy the a the code obtained from last command like "c1530713-aec2-4415-a6b5-b057928c7e5f" and use in the following:

vagrant package --base c1530713-aec2-4415-a6b5-b057928c7e5f --output window7.box
```
 vagrant init window7
 vagrant up window7 --provider=libvirt 
 vagrant box list
```
You need to install some vagrant plugins like libvirt and mutate. Mutate will convert .box to libvirt VM:

vagrant plugin install vagrant-libvirt vagrant plugin install vagrant-mutate
Converting vagrant box to libvirt:

vagrant mutate window7_.box libvirt
Now you can initialise the vagrant VM. If any error persist move to edit your Vagrant file. Like for me I uncomment the line starts with config.vm.network and then run command below:

vagrant up --provider=libvirt

This is how I was able get rid of this error completely
