Hi, Chris:
    OK, I see, we are not talking the same thing, I am talking the "Source 
code", but you just talking the
"Prebuilt Hypervisor toolkit without the source code but only a prebuld binary: 
kernel.elf", the difference
between us is: the source code fetched from "git://git.l4dev.org/codezero.git" 
which not updated 23 months
ago, and the thing your talking---exactly the toolkit is another git 
repository: "git://git.l4dev.org/codezero-toolkit.git"
which without the kernel's source code and not updated 15 months ago.

    You see the  the difference?

Regards,

Charles, Liu
