How to test Debian Edu CD/DVDs with Qemu
There are three steps required to test the debian edu installation.
- Fetch the DVD image
- Prepare a test machine
- Do the DVD installation
The first step can be done using HTTP, FTP or rsync. For repeated testing it is best to use rsync, as it will only transfer the changes between DVD versions instead of the entire DVD. The second step can either be done using a real machine, or in a virtual machine like qemu or vmware, and the last step is fairly straight forward.
Fetching the DVD image
There are a few slightly different DVD/CD images being generated, the sarge and etch images are the ones indented for new releases, and the sarge-test and etch-test images are the ones with new packages to be tested before they are move into the DVD/CDs indended for a new release.
In these examples I use etch-test as the sample image. Replace that string with sarge, sarge-test or etch if you want to use another image.
rsync -vt ftp.skolelinux.no::cd-etch-test-dvd/debian-edu-amd64-i386-powerpc-DVD-1.iso debian-edu-amd64-i386-powerpc-DVD-1.iso
Using HTTP and FTP
wget http://ftp.skolelinux.org/cd-etch-test-dvd/debian-edu-amd64-i386-powerpc-DVD-1.iso ncftp ftp ftp://ftp.skolelinux.org/cd-etch-test-dvd/debian-edu-amd64-i386-powerpc-DVD-1.iso
There is also netinst CDs available using the cd-etch-test, cd-etch-test-amd64 and cd-etch-test-powerpc directories.
Prepare a test machine
Preparing and booting a qemu machine
First, install a few extra packages. This part need to run as root. The kqemu part is to speed up the qemu execution.
sudo aptitude install qemu sudo aptitude install kqemu-source kqemu-common sudo module-assistant prepare sudo module-assistant build kqemu-source sudo module-assistant install kqemu-source # or simply: sudo aptitude install kqemu-modules-2.6-686 kqemu-common sudo modprobe kqemu && sudo sh -c 'echo kqemu >> /etc/modules'
Then create a 6 GiB virtual disk used to install into.
qemu-img create virtual-hda 6G
Doing the installation
Finally start the qemu instance first booting from the DVD image with 128 MiB of RAM, and next boot from the virtual hard drive.
qemu -m 128 -boot d -cdrom debian-edu-amd64-i386-powerpc-DVD-1.iso -hda virtual-hda
This should be fairly straight forward. Note that a full disk on the machine hosting qemu will appear as failing hardware (broken disk) in qemu.
To enable manual partitioning and the barebone profile option, boot using "linux debian-edu-expert" on the first prompt. To get full manual control over the installation, boot using "expert" on the first prompt.
Running the Machine
After you complete the installation, the machine reboots. But to do this in qemu you basicaly run qemu again using a different boot device.
qemu -m 128 -boot c -cdrom debian-edu-amd64-i386-powerpc-DVD-1.iso -hda virtual-hda
Don't forget to write bugs about new issues you discover.
Setting up a virtual qemu network
