Simultaneous Running HAXM AVD Emulator Limit

To elaborate on the title, I'm running many simultaneous AVD's for my automated build/test processes (think concurrent builds for a project, or multiple projects building at once). Most problems that people have with running multiple HAXM accelerated AVD's at once is memory related. THIS IS NOT MY PROBLEM (I think). I have a pretty beefy i7 machine with 32gb of ram. When installing HAXM, I allocated 28gb (sorry, I can't post more pictures without more rep).

Here is my AVD configuration(s). Observe, only 1024mb of memory allocated per emulator:

I can run 8 emulators at once, I would post an image if I could. I'm only using ~16gb of my 32gb of ram when they're all running. (2048mb per emulator at this moment in time). No matter what I do, I cannot run more than 8 emulators. I can run 8 emulators with 1gb, 2gb, or 3gb memory allocated per device simultaneously. I've tried 32bit vs 64bit intel images. There is clearly a limit beyond that of memory that is enforcing this.

The error message I get when starting my 9th emulator (Note, I started counting emulators at 0):

9th emulator boot error

"Failed to create HAX VM. No accelerator found."

The only thing I could think of where the number 8 might be coming from would be the fact I have 4 cores == 8 logical processors. That's a wild guess though. Any help would be greatly appreciated.

It is due to a hardcoded variable in the HAXM. You can solve this problem by downloading the latest HAXM from the Github page, which will set an limit of 64 guests instead of 8.

Type this in the command line:
