We have just returned back from Germany, where I was presenting OpenVZ at Linux World Cologne. For the first time, we had a separate dedicated booth, and we really enjoyed that.
For those three days, we have met hundreds of people, distributed about 100 of OpenVZ DVDs and booklets, and said about million of words telling and showing people what is OpenVZ, how it can be used, what are pros and cons and so on. Surprisingly, a lot of people found it's just what they need.
We also met a number of existing OpenVZ users — for example, one was using it in a small (25 permanent employees + 25 interns) commercial company, where they need a Samba server, a Collax server, and development server, all of three for some reason requiring three different Linux distributions to run on. So, instead of having three servers, they used OpenVZ to create three VEs. It is a production environment working flawlessly for a few months.
I have also met a student who did his thesis on comparing Xen and OpenVZ performance — the thesis is in German but we might translate a part of it later. If you guessed that OpenVZ outperforms Xen than you are damn right.
Finally, in a true spirit of open source, we helped a Debian OpenVZ user to fix a minor misconfiguration and he was finally able to run OpenVZ on his notebook. He is using OpenVZ as a replacement for UML.
