»Setting small fully redundant datacenter on a budget. How hard can it be?«

Spoiler: It turns out to be very hard!
I want to tell you about the lessons that I have learned the hard way when I extended my datacenter from one server setup to a multiserver setup. I tested out several ways to actually do the virtualization on those systems, from lxc over kvm to libvirt and finally oVirt which I currently use.
I had some brilliant missideas while planning this like putting storage and computenode services on the same host or even writing my own virtualization engine in ansible, because no one did it before, needless to say: that was a failure.
And while testing out ways to set it up, I also discovered some very interesting bugs on the way.
