Thanks for the updates svij. A number of you offered help in hosting the
service. Thanks for all of your offers! Since Max had both the hardware and
ability to host already, it seemed to make sense to allow him to self-host
this.
So, Max will work on getting the jenkins visible to everyone publicly and
reply back with it's location. Everyone will be able to view, and those in
the testcase admins group (https://launchpad.net/~ubuntu-testcase) will be
able to also build and rebuild jobs.
Since we'll want to maintain the jobs running the tests collectively, I've
setup a new launchpad project to host the job code.(
https://launchpad.net/community-image-testing). It's blank for now, but as
Max sets up the initial jobs, he'll commit to it. From there we can handle
job modifications collectively as a group via source control. Anyone will
be able to suggest changes as merge proposals, the same as any other
launchpad project. In this way, should we ever wish to, or need to migrate
to a new jenkins, it should be easy to do so.
As always, thoughts, comments, suggestions, etc are most welcome! It would
be helpful to get feedback on how we're setting this up to make sure
everyone can collaborate sanely.
With the jenkins and hosting issue out of the way, we really need to solve
the issue of the tests not running and ubiquity crashing while trying to
execute the tests.
https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1487098
As always, those brave souls who are willing to follow
http://bazaar.launchpad.net/~ubuntu-installer/ubiquity/trunk/view/head:/autopilot/README.md
and try and get ubiquity to run the tests and figure out the issues and/or
fix the tests themselves would be most appreciated!

Hi,
I have a few updates for you. I tried to run the tests on ec2 and on
digital ocean. The tests uses qemu with kvm to boot the isos.
Unfortunately I turned off the usage of kvm, which resulted in two
things: a) It's rather slow. b) irqbalance keeps crashing.
I've tried to run the tests on different days, with differents isos and
different ubuntu versions. The main issue was, that irqbalance on the
slave (the booted iso system) keeps crashing. Atleast it did work at the
beginning - sometimes.
I would suggest to run the tests on real hardware. Running the tests in
the cloud doesn't seem to be really doable, if irqbalance keeps
crashing. If someone knows how to fix that, it might be a bit different.

-svij and shrini agreed to setup a test jenkins instance to help answer
our lingering questions on what we need. Specifically they'll be
looking at
where should we host this?
can we test in the cloud?
what type of setup should we have (how many slaves, how many instances)?
and trying to get us all setup with a jenkins instance we can add jobs
to and iterate on moving forward.
I've set up an Jenkins-Master server today, but there isn't anything yet
(http://jenkins.svij.org). It runs on digital ocean (for 10$/month +
2$/month for backups)
I also had a look into the tests to check the other questions. The sad
thing is, that we can't host this on digitalocean, because digitalocean
doesn't support nested kvm virtualisation. The tests do use local kvm on
the host machine.
We have three options now:
* rent a physical machine, where we can run the tests on local kvm
* buy a physical machine and host that somewhere (e.g. at someones
home…)
* rent a amazon ec2 instance (which is virtualized but uses hvm with
xen)
All three options are kind of expensive. The first option probably needs
a contract for atleast a year (depends on the provider). IMHO the best
solution is to use amazon ec2. We could write a script which starts an
fresh ec2 instance and runs the tests. After that we can drop the ec2
instance again. Running the ec2 instance (t2.medium with 2GB RAM) 24/7
would nearly cost 40$… but they were idling most of the time anyway. So
the best and cheapest option is to only use them, when there are new iso
images to test. The jenkins master server needs to run 24/7, that could
continue to run on digital ocean.
I don't have experience with amazon aws/ec2, if theres something wrong,
please correct me.
Cheers,
Sujeevan
