 QEMU NOTES
------------

Since the qemu docs blow, I'll make some quick notes here for how to get a
system running for baselayout testing.

- create rootfs (feel free to tweak 500M):
        $ dd if=/dev/zero of=root.img bs=1M count=500M
        $ mke2fs -F -j root.img
- install Gentoo stage3:
        $ mkdir loop
        $ mount -o loop root.img loop
        $ sudo tar pjxf stage3-x86.tar.bz2 -C loop
        $ sudo chroot loop
        <all you really need to configure is like /etc/fstab>
                /dev/hda / ext3 noatime 0 1
        $ umount loop
- create an x86 kernel from a vanilla tarball:
        - make sure you enable serial console support
        - you shouldn't need any modifications, just grab a recent vanilla
- run qemu:
        $ qemu \
                -hda root.img \
                -append "root=/dev/hda console=ttyS0" \
                -kernel your-compiled-vmlinux \
                -nographic
