Running the new Intel emulator for Android

Question

Lately Google and Intel have published a new way to run the emulator, which should work much better than the previous version (which has emulated ARM CPU). Here are some links about it: this and this.

However, after installing the new components and creating a new emulator configuration as instructed, I get an error and I also can't see any improvements. I've tried both API 10 and API 15, and with GPU enabled and disabled. None of those configurations helped. I've also tried it on two different computers and didn't get any boost (and got the same errors).

It seems that on the posts I've read about it, nobody had any problems with it and all report a much faster emulator.

The error it shows is:

emulator: Failed to open the HAX device! HAX is not working and emulator runs in emulation mode emulator: Open HAX device failed 

Why is it happening, and is there a way to fix it? Is there anyone else who gets those errors or vice versa?

By the way, I have an Intel CPU, if that could be a problem.

EDIT:

here's what I see in the BIOS, so it should be available... :

Answer 1

I had the same issue, solved it by Installing the Intel Hardware Accelerated Execution Manager. Download it with the SDK Manager, it's in Extras. After this, go to the folder

[Android SDK Root]\extras\intel\Hardware_Accelerated_Execution_Manager

then run IntelHaxm.exe and install.

Here the link of the Intel Hardware Accelerated IntelHaxm.exe for Microsoft Windows,Mac OS* X, and Linux Ubuntu

You'll get the following message if you don't have virtualization enabled in your BIOS:

Answer 2

Small Note for Windows 8 user, Intel HAX will not work if Hyper-V feature is enable. Hyper-V (like most of the virtualization tech) will exclusively lock the VT extension witch will prevent HAX to work properly. A workaround if you “need” Hyper-V too might be to stop manually the Hyper-V services when you need HAX (haven’t tested it yet through).
