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.
