Proxmox is an example of the end product being greater than the sum of parts. All the technologies used to build Proxmox are not unique however putting them all together and adding a nice interface is. Overall I am very impressed with the ease of use and quality of the software. The flexibility that is provided by virtualization plus the ease of administration provided by Proxmox is a great combination for anybody looking to use virtualization.
Introduction to Proxmox VE
Proxmox VE is virtualization platform based on Debian Etch x86_64. It comes as a self contained ISO installer, just pop the CD on supported hardware and it installs automatically because of this it will only run of 64bit machines. That makes testing out a Proxmox server impossible on older hardware.
From the Proxmox wiki one of the goals of the Proxmox project is to "Setup a complete virtual server infrastructure within 1 hour" it seems to achieve this goal as a base install takes about 30min to install and get a basic configuration completed. Install was smooth and only a few tweaks had to happen after the default install to get the server working as I wanted it. Common things like changing the root password, securing ssh, changing the ntp server and some other minor tweaks.
