Intel(R) Hardware Accelerated Execution Manager (HAXM)
with Intel(R) Virtualization Technology (VT) 
for faster Android* Emulation


Version 6.1.0
----------------------------
Changelog
----------------------------
- Updated HAXM API version to 4. API v4 supports removing an existing memory mapping and will be used (and required) by a future release of QEMU.
- Fixed VGA emulation (requires a future release of QEMU that supports HAXM API v4).
- Fixed other issues that had prevented certain QEMU disk images (Debian, CentOS, etc.) from booting.

----------------------------
Overview
----------------------------
The Hardware Accelerated Execution Manager (HAXM) is a hardware-assisted virtualization engine (hypervisor) that uses Intel(R) Virtualization Technology (VT) to speed up Android* development.

This software:
-Uses Intel VT, available on selected Intel processors
-Provides hardware-accelerated emulation of Intel(R) x86 Android virtual devices
-Integrates with the Android SDK

----------------------------
Prerequisites
----------------------------
Intel(R) HAXM requires the Android SDK to be installed (version 17 or higher).
For best performance, using SDK version 20 or higher is recommended.

Please refer to the Android developer website (http://developer.android.com/sdk/) for more information.

----------------------------
System Requirements
----------------------------
Hardware Requirements:
-Intel(R) processor with support for VT-x, EM64T, and Execute Disable Bit
-At least 1GB of available RAM

Supported Operating Systems:
Windows* 10 (32/64-bit)
Windows* 8.1 (32/64-bit)
Windows* 8 (32/64-bit)
Windows* 7 (32/64-bit)
Mac OS X* 10.10, 10.11, 10.12
Note: 
Test was NOT conducted on Windows* XP since Microsoft* will not offer support for this version. 

Important:  
1. Intel HAXM cannot be used on systems without an Intel processor, or an Intel processor lacking the hardware features, described in the "Hardware Requirements" section above.
To determine the capabilities of your Intel processor, please visit http://ark.intel.com/
2. Before installing HAXM 1.1.5, the previous version (1.1.4 and below) must be uninstalled using:
	sudo /System/Library/Extensions/intelhaxm.kext/Contents/Resources/uninstall.sh


Additionally, Intel HAXM can only accelerate Android x86 system images for emulator-x86. 
HAXM has been validated with x86 system images provided by Intel at http://software.intel.com/en-us/android and Android SDK Manager.

Known Issues: 
-Coexistence problem with VirtualBox versions newer than 4.2.8 on Mac OS X*
-HAXM driver does not support emulating a 64 bit system image on Intel systems based on Core microarchitecture (Core, Core2 Duo etc.). All systems based on Nehalem and beyond are supported. (Corei3, Core i5 and Core i7 machines).
-If DriverVerifier is running on a Windows System on which HAXM is installed BSOD can happen during HAXM uninstall. Check the following link for more information from Microsoft.http://msdn.microsoft.com/en-us/library/windows/hardware/ff545448(v=vs.85).aspx
-On Windows platform using sc query command on command line will show the driver to be in Running state even if VT is disabled in BIOS. The Android SDK gets this information from HAXM driver whether VT is enabled or not and displays it to user when the user starts to emulate a device. The information in the SDK is the most accurate information for the state of the HAXM driver.
-On Windows 8, 8.1 and 10, it is recommended to disable Hypervisor from Windows Features in order for the HAXM driver to properly function.
-Some antivirus software like Avast, which use VT-x, will temporarily cause the HAXM driver to display that VT-x is not supported. Just wait for the scan to finish and then the installation can successfully continue.
-In Mac OS X, it can be downgraded to some old versions, but it is recommended to use latest version of HAXM.
