Proxmox VE is a “bare metal” ISO Linux distribution that is a virtual machine platform. It is geared towards enterprise users and designed to be installed on enterprise grade hardware. The Proxmox VE distribution combines two virtual machine technologies; KVM and OpenVZ as well as a web interface to manage everything. Proxmox VE also integrates into its web interface a way to manage multiple computers as a cluster. For the rest of the article Proxmox VE shall be referred to as PVE. This article is written about PVE 1.1, the latest stable release.
PVE comes as an ISO installer and is not designed to be added onto an existing OS. PVE is built on a stripped down version of Debian. PVE does not come with any graphical interface other than the web based one. It requires a “big iron” server. The server needs to support Intel or AMD virtualization processor extensions and hardware RAID is recommended.
PVE's web interface is very elegant and exposes most underlying functionality of both KVM and OpenVZ. The interface is fairly intuitive but like all programs it has a learning curve. The interface gives basic information for your virtual machines, containers and for the host node. It provides stats on disk, memory and CPU usage.
