If you see something like this when booting Android Emulator:
1 2 3 4 5 6 7 8 | Failed to sync vcpu reg emulator: Serial number of this emulator (for ADB): emulator-5554 Failed to sync vcpu reg emulator: ERROR: Unfortunately, there's an incompatibility between HAXM hypervisor and VirtualBox 4.3.30+ which doesn't allow multiple hypervisors to co-exist. It is being actively worked on; you can find out more about the issue at http://b.android.com/197915 (Android) and https://www.virtualbox.org/ticket/14294 (VirtualBox) Failed to sync vcpu reg Failed to sync vcpu reg Failed to sync vcpu reg Internal error: initial hax sync failed |
It is likely that one of the following app is running:
- Virtualbox
- Docker
- Other virtual machine applications
Stop all of them, and try again.
