It really depends on what you call "developer version". As far as I know,
there is nothing but dev trees around ;-).

First, my tree (the second one) does support the A15. Otherwise I'd have a
hard time testing my own code... Which branch are you looking at? Please
note that the KVM branches in this tree are under heavy development, and
are only suitable if you don't mind frequent rebases and regular breakage
due to bleeding edge code.

If you want something more stable, you probably want to have a look at
Christoffer Dall's tree:

You also may need to join the KVM-ARM mailing list (named android-virt for
historical reasons):
https://lists.cs.columbia.edu/cucslists/listinfo/android-virt

One last thing though: all our developments are done on the Cortex-A15
FastModel. In your email, you keep mentioning the VE board. For the time
being, we have nothing running on the real hardware, only on the model.

Good luck! ;-)
