Proxmox is a Debian-based bundle of OpenVZ, KVM, and a Web based management GUI. It supports high-performance container-based virtualization of Linux workloads, as well as lower performance KVM hardware assisted virtualization. It supports any hardware that the Linux kernel supports, and will permit live migration of running OSIs with shared storage configurations (DRBD, CIFS, NFS, etc.). It comes bundled with many virtual appliance templates (Drupla, Moodle, FreePBX, etc.) and generic OSI appliances (Fedora, Debian, Ubuntu), as well as a faculty for building arbitrary Linux based appliances. It can be used for virtual desktop infrastructure (VDI) and virtual server infrastructure (VSI). It supports almost any x86/x64 OS in a KVM container and any Linux-based OS in OpenVZ.
