Since the qemu docs blow, I'll make some quick notes here for how to get a
|
| 6 |
|
|
system running for baselayout testing.

|
- create rootfs (feel free to tweak 500M):
|
| 9 |
|
|
$ dd if=/dev/zero of=root.img bs=1M count=500M
|
| 10 |
|
|
$ mke2fs -F -j root.img
|
| 11 |
|
|
- install Gentoo stage3:
|
| 12 |
|
|
$ mkdir loop
|
| 13 |
|
|
$ mount -o loop root.img loop
|
| 14 |
|
|
$ sudo tar pjxf stage3-x86.tar.bz2 -C loop
|
| 15 |
|
|
$ sudo chroot loop
|
| 16 |
|
|
<all you really need to configure is like /etc/fstab>
|
| 17 |
|
|
/dev/hda / ext3 noatime 0 1
|
| 18 |
|
|
$ umount loop
|
| 19 |
|
|
- create an x86 kernel from a vanilla tarball:
|
| 20 |
|
|
- make sure you enable serial console support
|
| 21 |
|
|
- you shouldn't need any modifications, just grab a recent vanilla
|
| 22 |
|
|
- run qemu:
|
| 23 |
|
|
$ qemu \
|
| 24 |
|
|
-hda root.img \
|
| 25 |
|
|
-append "root=/dev/hda console=ttyS0" \
|
| 26 |
|
|
-kernel your-compiled-vmlinux \
|
