For those that are not familiar with Proxmox, it is a Debian based virtualization OS that has a web based front end for administration of the VPS's. It has to be ran on a dedicated server, and then you can create your own VPS's from it. I use it to run most of my sites on currently.
The newest release has a built in firewall... I haven't started playing with it yet (I use CSF and will probably continue to do so) but for those that don't it will be beneficial.
The new default VNC console is now HTML5 and is no long a Java based.
