I am finally back at home after the Linux Tag event, and can now summarize it.
We were together with Kirill Korotaev (a.k.a. dev), our kernel team leader, at the OpenVZ booth shared with SWsoft and their partner Thomas Krenn, so we had our own "little corner" to show OpenVZ on our two laptops. We also had the leaflets (in English and German) and a DVD to give away.
On the laptops we were showing command line interfaces, how to use vzctl to create VEs and set its resource limits, how user beancounters and disk quota works etc. etc. But the most amazing thing was definitely the live migration feature, which was shown using X screensaver running inside a VE and accessible via a VNC client. During the migration the screensaver was paused for a few seconds and then continued to run — but on the another laptop! So, from a user's point of view, migration looks like some kind of network delay.
Also, on May the 5th (which, coincidentally, was also my birthday) me and Kirill held a 1.5 hour workshop about virtualization and OpenVZ. Half of the workshop was a presentation on different virtualization technologies in general, and OpenVZ in particular. Another half was a live demo of some features OpenVZ have, including of course the live migration demo.
The workshop was great and attracted about 50 people (or might be more) — the room was pretty full. We had a lot of good questions, and many people came to our booth after the workshop to ask some more questions.

We will be at OLS this year - unfortunately just as visitors. Anyway, if we will meet I can show you what OpenVZ is and what it can do.
Also, my presentation from Southern California Linux Expo is available from socallinuxexpo.com site: PDF, ODP.
