Thank you for helping me figure out what's wrong. Most probably I'm using trans=mmio incorrectly, but unfortunately I don't know how to use it properly.

All I've changed is adding ,trans=mmio to the lkvm command line, and it ceased working because of that. What should I define and where? Is this documented somewhere? Could you please send me the shortest example (lkvm command line and possibly guest commands) which works for you?
