Subject: how to debug kernel in qemu using ubuntu image

Hello all,

I'm using linux-0.2.img image(which is a light linux image) to debug
kernel using Qemu. I'm working on IO schedulers' optimization. As Qemu
boots kernel, IO scheduler sends read requests to disk. Also by
entering commands such as 'ls', it sends read requests. I'm looking
for a way to send write requests. Thus I thought that using a
benchmark which sends both read and write requests, is suitable, but
as linux-0.2.img is a very simple and light image, it is almost
impossible to setup heavy benchmarks on it. So I want to use an ubuntu
image instead. But I don't know where I should see kernel printks.

Thanks in advance
Regards,
