Today Proxmox VE 4.2 was officially released. Proxmox VE is a popular virtualization platform among STH readers. It is a Debian/ Linux based system that wraps KVM hypervisor, LXC containers and clustering all in an easy-to-use UI. It also supports ZFS storage and Ceph storage making Proxmox VE clusters a fairly flexible choice. If you are reading this article, at least part of it is likely served by our Proxmox VE 4.1 cluster that runs Ceph and ZFS storage back-ends. Best of all, the platform offers most of this functionality in a community edition with commercial support options. We also have numerous folks in the STH forums that utilize Proxmox VE on a daily basis.
