On 29 April 2005 two Linux developers in Vienna, Dietmar and Martin Maurer, released Proxmox Mail Gateway and registered the GmbH. Three years later came Virtual Environment: OpenVZ + KVM, a browser, Debian. In 2026 Proxmox VE 9.2 (21 May) runs kernel 7.0, QEMU 11 and LXC 7 on Debian 13, the company still belongs to its founders, and 24\/7 support starts in October. Two million three hundred thousand hosts. No private equity.<\/p>\n

OpenVZ had no backup or GUI. KVM was emerging in the kernel. The Maurers brought the two problems together. 29 April 2005: Proxmox Mail Gateway 1.0 and Proxmox Server Solutions GmbH. 15 April 2008: Proxmox VE 0.9\/1.0 \u2014 web interface, containers and full machines in the same dashboard, the trick VMware charged for in modules.<\/p>\n
The company is Austrian, independent, 100% founder-owned. AGPLv3 starting with VE 2.x (1.x was GPLv2): anyone modifying it and offering it as a service must give back the code. A subscription doesn't unlock features \u2014 it unlocks the enterprise repository and SLA.<\/p>\n
Until 3.4 containers used OpenVZ. In 4.0 (6 October 2015) that became LXC: a new kernel, unprivileged by default later on, a new HA Manager. KVM covers Windows and anything needing VT-x\/AMD-V. On storage: a ZFS plugin in 2014, Ceph that same year, thick LVM snapshots in 9.0. Corosync clustering, REST API in 2.0, GUI backups, live snapshots. One ISO. One apt. No separate vCenter.<\/p>\n
The ecosystem grew alongside VE: Backup Server, Mail Gateway, and in December 2025 the stable Datacenter Manager 1.0 \u2014 multiple clusters on one screen. On 5 August 2026 VE for ARM64 arrived.<\/p>\n
Each major VE version follows a Debian release. 8 = Bookworm (2023), Proxmox EOL August 2026. 9 = Trixie (August 2025). 9.1 (November 2025) began creating LXC containers from OCI images. Version 9.2<\/strong> (21 May 2026): Debian 13.5, kernel 7.0, QEMU 11.0, LXC 7.0, ZFS 2.4, Ceph Tentacle, dynamic load balancer, WireGuard in SDN, custom CPU models, HA arm\/disarm for maintenance. Rolling: the official advice is to stay on the latest stable release.<\/p>\n April 2025: the GmbH turns 20. August 2025: VE 9 on the anniversary, with Broadcom having just raised vSphere prices. September 2026: Proxmox North America Inc. and 24\/7 support starting 19 October (Premium; Standard in Q4). The company's own numbers: 2,3 million VE servers, 60 thousand enterprise plans, 3 thousand partners. It's still the hypervisor a homelab installs on the weekend and a European datacenter uses during the day \u2014 the same ISO.<\/p>\n Proxmox is KVM (type 1 through the kernel) + LXC. Xen is another type 1, outside the kernel \u2014 The history of Xen<\/a>. The Citrix product is XenServer<\/a>; the free fork is XCP-ng<\/a>. On a laptop, the cube: VirtualBox<\/a>.
