@Falko, Per your OpenVZ installs. They are all actually text book perfect install guides. However I think you should add a section on how to better setup and trouble shoot network connect issues. There seems to be a lot of issues out there like mine where you do the proper out of the box install that Openvz says should work, but we have been unable to get networking to work at all. I am hitting tons of forums, and even the OpenVZ forum and this problem seems to be quite common. Just this no answer to it out there. All the threads died off with NO solutions. I think a simple revisit or combined guide quite for everyone to use to trouble shoot would be nice.
I would have added such hints if I had encountered them, but I had no issues at all. For me, it worked exactly as described in my tutorials.
