The difference being that I didn't run the MAKEDEV script but just copied my hosts' /dev directory over.
(If this was a bad idea, let me know). I also created the udb[a-h] devs. If anyone is interested in my script for this I'd be happy to post it.
It is similar to Matt Lawrence's script. Unfortunately, my experience with Matt's script was more difficult than I expected, but I might have skipped a step.
Host is running 2.6.11.6 vanilla. Guest is 2.6.11.6 vanilla. This combination does not induce high (1.0+) uptime on host with idle guest. Uptime on guest reads at 1.00.
Question: I get some stack traces during boot. Are they signifigant and should I patch host kernel to get rid of them? They look like some kind of attempted operations against tty0.
If this is noise, I do appologize. I must say I'm happy to be able to get to play round with some vanilla kernel compiles that work! Thanks!
