Volunteers needed -- Automated Image Testing for flavors

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.
