[Users] OpenVZ 8.0 - Alpha Release

[Paulo Coghi - Coghi IT]

Hi Maik!

Congratulations for your incredible achievement! We are really excited
about it! Also, congratulations on the libvirt integration! It will help
OpenVZ be adopted in more scenarios!

Silly question: with libvirt as the main management API from now on, will
we still be able to change resources (CPU, RAM, storage) individually and
without reboot, as in previous versions of OpenVZ?

About tests, we will start testing soon, in the following week.

We use OpenVZ exclusively for systems containers, and our tests will focus
on multi-service scenarios, with OpenVZ containers running:

 - email (Postfix, Dovecot, Spamassassin)
 - DNS (Bind server)
 - web servers (mainly Nginx, but maybe Apache as well)
 - PHP
 - databases (MariaDB mainly, but maybe MySQL and PostgreSQL as well)
 - general services like SSH and networking

It will be an honor to provide as much feedback as possible!

As we stated before, in our vision, OpenVZ is by far the most mature,
performant, seamless and secure virtualization technology. It's unique.


Thanks again and see you soon with the test reports!
