How do I fix “Failed to sync vcpu reg” error?

Question

I\'m trying to use the Intel HAX x86 emulator for Windows (8, if that matters). I installed everything and created an AVD for the android version, and everything appears co

Answer 1

I'm running boot2docker vm, just down it solved the issue.

boot2docker down

Answer 2

I had this problem. For me it was the HAXM version.

When you get a new version of HAMX through the SDK Manager, it tells you that it is installed. It is not. You must go to this folder:

<Android SDK>\extras\intel\Hardware_Accelerated_Execution_Manager\

and run intelhaxm-android.exe manually. In my case, I had 1.0.6 and upgraded to 1.1.

I think that what caused the error in the first place was that some other part of the SDK that I had updated needed 1.1.

As mentioned by other answers, make sure no VirtualBox and docker service is running with following command in mac. (systemctl in Linux)

$ launchctl list | grep 'VirtualBox\|docker'
-       0   com.docker.helper
640     0   com.docker.docker.2032
31736   0   org.virtualbox.app.VirtualBox.948

If so, kill the VBox and docker service.

launchctl stop org.virtualbox.app.VirtualBox.948
launchctl stop com.docker.docker.2032

Answer 4

I was getting the same error. I'm guessing there are various reasons for this error, but in my case it was because of a service named ".NCG". The service is Network Content Guard by Inka Entworks, and seems to be some type of DRM solution. Once uninstalled, the emulator worked fine using HAX.

Answer 5

I was on a mac and had this problem. I did not think I was running a VM (I have vbox but it isn't running). I restarted my computer and before starting any other apps I tried the emulator and it works fine.

Answer 6

Yes, VirtualBox VMs have to be stopped. I also had to stop Docker for Mac. The error message only mentions VirtualBox, which confused me a little until I realized Docker for Mac is running xhyve.
