did you build that yourself?
i've managed to create a kvm minimal ubuntu 8.04 server with assp 1.7.x and will try another with 2.x (i'm learning the system)
i think it its web gui is a mess, but many people appreciate assp and find it effective and useful...
i don't think its install instructions, with all the perl modules, etc, it is really that easy to understand (wiki docs) so it could be useful to have as an openvz appliance
do you use it in production? how much ram/disk you assigned (and what mail+spam load has your server)? what's the base os system?
could you upload that on pve wiki site?
