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.
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.
