Original GitHub issue: https://github.com/netblue30/firejail/issues/6188

When I have virtualbox already in use and I try to run android emulator through firejail with android studio profile, I get this error:

ioctl(KVM_CREATE_VM) failed: 16 Device or resource busy
qemu-system-x86_64: failed to initialize KVM: Device or resource busy
WARNING | QEMU main loop exits abnormally with code 1

Describe the solution you'd like

I would like to have both virtual box and a firejailed android emulator running at the same time on the same computer
No idea how do do this.
I can run multiple virtualbox on same computer so I guess it's technically possible to run android emulator and virtualbox at the same time.

Describe alternatives you've considered

I will try to run both virtualbox and android emulator through firejail, but not sure this would resolve the error.

Additional context

Linux Mint 20.3
Firejail version 0.9.72

Does it work if:

Both programs are executed without firejail?
KVM is disabled in the android emulator?
An architecture other than x86_64 is used in the android emulator?

Depending on your operating system and hypervisor, you may not run software that uses another virtualization technology at the same time that you run a VM-accelerated emulator.

Did you make sure this is caused by firejail? Did you tried with --noprofile?
