As the first step in moving my automated d-i install testing away from the dilab and over to emulation, I've added support to the d-i regression tester (digress) to use qemu for serial-console based CDROM installation tests. It was fairly straightforward to do that, since digress already supported bochs and hercules.
I don't currently have an enourmous fast machine I can run qemu on. Actually, all of my servers, including my only amd64 server, have xen on them, which isn't ideal in combination with qemu (no kqemu..). So I thought I'd put this out as a howto, in the hope that lots of people will set up their own automated tests. If you do, please mail me and let me know, and I will aggregate all the tests together into a nice status page.
Here's how to set it up:
sudo apt-get install qemu subversion libexpect-perl expect lockfile-progs
sudo apt-get install kqemu-modules-2.6.18-4-686# or similar, using unstable
sudo modprobe kqemu
svn co svn+ssh://svn.debian.org/d-i/trunk/scripts/digress
- Now edit
digress/schemes/qemu/common, and set
ISOto point to the CD image you want to test. You may also want to tune
READMEhas more details about all the config options.
- Also edit
digress/schemes/qemu/d-i, and change "url=kodama" to control where d-i will download its preseed file from. Until qemu bug #414342 is fixed, it can't support colons or slashes in the url to the preseed file, so the example is taking advantage of the default url guessing in d-i, which will look in eg
http://kodama/d-i/etch/./preseed.cfg. Put in your hostname and set up a preseed file.
digress/preseed.cfgis a reasonable starting point.
- To start a test, run
./test-harness qemu d-i
- The test will proceed automatically; digress will hit Enter at any prompts. Your preseed file should take care of any other choices.
- To cron the test, run
cd ~/digress; ./daily-tests qemu d-i(be sure to update the CD image too). This will drop logs into
digress/logs, and if you put that directory up on the web, I can produce a nice status page.
(Wonder if I should make a package of digress?)
A few ideas for things to test:
- netinst iso
- businesscard iso
- netboot mini iso
- true netboot (qemu -boot n)
- gnome desktop install
- kde desktop install
- xfce desktop install
- web server install
- small disk
- all kinds of fun combos of the above, like lowmem gnome+web server install on lvm
