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) f         


        

Answer 1

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
