OpenVZ vs. Scalix
We win again. I wanted to run Scalix for a client, inside of a VE/CT/whatever, and I tried using Fedora Core 7 to do so. I was unable to make the installer work and didn't see much in the way of help from Scalix. Here is a link to the Bugzilla page. (Login Required) Here are the important bits. Aside from discouragement I didn't get anything from Florian... Nothing except responses that was. No one else seems to give a damn if I even exist.
Whatever. The point is that with some minor extra-effort, Scalix does indeed work inside of an OpenVZ container on Linux. My host OS is gentoo, running 2.6.18-028stab053.
The Scalix package is pretty great, just up the Java memory once you have it running. The instances (two) on a system shared by two different companies work great. We migrated to Scalix from Kolab. Outlook users (all two) are happy. Thunderbird users didn't see too much of a change.
Yay for us.
