MontaVista has KVM for MIPS on their product slides [1]. Maybe someone
has a good contact to them and can poke for more details. They probably
won't offer it for direct download but need to distribute it to their
customers as open source anyway.

Hi Jan,

Thanks very much for your information. I am not sure how they
distribute their source code. Anyone knows about that?

Jan, would you like to be one of the mentors of this project? Your
experience of KVM would be very helpful. Thanks

Your project is really interesting. But given that my bandwidth is
limited and I've already a different project proposal filed, I can't
commit myself to this yet. I may serve as a backup mentor, but no
promises at this point.
