Re: Setting up development environment using QEMU.

ss about how to do that? You need a full system, kernel is just the core. I suggest you using Debian stable images for QEMU at http://people.debian.org/~aurel32/qemu (ref: http://wiki.debian.org/QEMU) Or, use busybox to build rootfs like what I am doing: https://github.com/adam8157/kernel
