I hope most of you facing this, I searched all over internet and couldn't find possible solution for this.
I am totally wasting my time researching on this and finally landed here for your help.
I am using Android studio 2.1.2 on windows 10 x64bit machine and android studio emulator is not running at all. Below is the console message.
C:\Android\Sdk\tools\emulator.exe -netdelay none -netspeed full -avd Nexus_6_API_22
emulator: WARNING: Crash service did not start

HAX is working and emulator runs in fast virt mode.

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)
