OpenBSD on OpenBSD with qemu through the network only?

[Uwe Dippel]

I would like to set up a virtual/emulated OpenBSD machine on an existing 
OpenBSD box; using qemu. The guest will only be accessible through the 
network (ssh), under an address different from the host IP; though 
through the same physical NIC.
I wonder if anyone has some experience or a link about this; otherwise 
I'll have to step-by-step myself through this.
Also, it seems that I can't install a qemu-harddisk-image on my OpenBSD 
boxen, since it needs graphics, right? So I'll have to use Ubuntu (e.g.) 
to create that image, and transfer it and start it on the console-only 
OpenBSD. Would that work?
