Thank you for the clarification, I was puzzling over similar issues. You could also consider 9vx <http://swtch.com/9vx/> especially if you are tempted to try running under Qemu or some other virtualised environment. Although I'm only at the exploratory stage, I find 9vx more useful than 9front.
I also use the Raspberry Pi image <http://plan9.bell-labs.com/sources/contrib/miller/9pi.img.gz> which is surprisingly easy to install and use. I found it easier to get going than Bell Labs release on various old i386 systems.
