Let me comment on that as well (ccing our users@ mailing list). Sure I'm
biased as well :)

Although this is indeed the first stable OpenVZ release, OpenVZ is
essentially Virtuozzo (without its bells and whistles), and Virtuozzo
for Linux is available for more than five years already.

Certainly you can compile OpenVZ from sources and use it on any Linux
distro. And yes, we are a part of Gentoo for about two months already
(with all the recent releases making their way into Gentoo in a very
timely fashion).
Debian is one of our goals (see roadmap
<http://openvz.org/development/roadmap>), although personally I am not a
Debian expert, still with some help from the Debian community we will
make it.

OpenVZ is supporting x86 (i386), x86_64 (AMD64, EM64T) and ia64
platforms. "Supporting" here means we have enough hardware for all the
three platforms, and do an extensive quality testing (functionality,
performance and stress tests) and security audit on all of them. It's a
pity but we can not provide the same level of support for other
platforms than those three.
Speaking of specific hardware, we are supporting the same set of
hardware that RHEL4 does, achieving this by backporting newer drivers
from mainstream, vendors and RHEL4 kernels. There is an official
Virtuozzo/OpenVZ HCL <http://virtuozzo.com/en/products/virtuozzo/hcl>.

There is an extensive 100-pages user's guide
(http://openvz.org/documentation/guides/).
Also all utilities has man pages, and there are some short to-the-point
howtos on the site and the forum.
We are working on more stuff, like QoS (User
Beancounters/FairScheduler/Disk Quota) paper.

There is a bug tracking (Bugzilla) and quite an active support forums,
also we have mailing lists and IRC channel (#openvz at freenode). We
also provide fee-based support for OpenVZ, done by the same excellent
team who supports Virtuozzo.

I can definitely say our security is higher than that of vanilla kernel.
We achieve that by two means: (1) sticking to older kernel and
backporting all the fixes from mainstream and (2) hiring top-rated
security specialists to do OpenVZ security audit.
