Answer 2

I received the follow error:

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)

To solve this problem I only needed to close Docker on Mac.

Answer 3

I was trying to emulate an Ionic 1 app on an Android emulator with ionic emulate android -lcs and encountered the same error: 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

I solved it by saving and suspending execution of all other running VMs with the following steps:

1) Quit Docker for Mac by clicking the whale icon in the top bar and selecting "Quit Docker". I believe this is required because the Docker Daemon (server) of Docker for Mac and Docker Toolbox automatically runs in a Linux VM when the Docker Client is running (you do not need to and cannot run it manually with dockerd or docker daemon). The Docker Client is running when the whale icon is in the top bar.

2) Stop all Vagrant VMs running on the host machine by running vagrant halt, as they may be using Virtual Box as the provider. Check their state changes to Powered Off by running vagrant status.

3) Stop all Virtual Box VMs by running virtualbox to open Virtual Box GUI and then Right-click any VMs and select Close > Save State

4) Close and re-open your Terminal window before retrying

Answer 4

I had the similar problem and I did the following:

1) Stopped the Docker for mac (Quit) 2) I use 2 monitor (One Mac Screen + Extended another screen), I disconnected the second monitor and it works fine.

Answer 5

Verify that you don't have more that one Virtual Machine running at the same time.

Answer 6

I simply stopped running Docker on Mac. The emulator then was able to run properly.
