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

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.
