How can I run the Android emulator together with another VM? Whenever I open an Android emulator when a different kind of VM is already running, I get the "usual" error messages:


  emulator: Failed to sync vcpu reg
  emulator: Failed to sync HAX vcpu context


Here it is recommended not to run another VM, but what if I need the another VM for development, or to run the server for my Android app on it? Is there a way to run a VirtualBox Linux guest VM and the Android emulator at the same time? My host OS is OSX if that matters.
You can’t run two different emulation stacks on your processor at the same time. Sorry, it wouldn’t happen.

Update: Your processor can only run one emulation system at the time. Kernel modules will “reserve” the right to use the processor’s emulation capabilities at the exclusion of any other emulator that want to use it. So you can only use VMware, VirtualBox, HyperV, etc. separately.
