So this sentence from the quick Installation guide is just false: "Alternatively, one can install OpenVZ on a pre-installed RPM based Linux distribution. Supported Linux distributions: Cloud Linux 7.*, CentOS 7.*, Scientific Linux 7.* etc"
You're telling now it's not an alternative. It should be removed from the guide, it's a huge change in the plans on how to deploy VZ7. For now, I was able to fire up a CentOS 6 host and then follow the guide for installing OpenVZ. With VZ7, I will need to be able to install from my own ISO image, this might cause problems with the hosters I use and I really need to evaluate if this is a good way to go. I really prefer OpenVZ container in favour of lxc and I'd like to stay with it, but I also need an easy way to fire up a new host system.

It is okay to do that. You're not alone with that. But the install guide should not state an alternative in the setup guide, that is no alternative. I will now need to re-evaluate VZ7 usage completly.
