XenServer review
A capable multi-host hypervisor for teams that need GPU virtualization and VM mobility.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
XenServer is a bare-metal virtualization platform for consolidating Windows and Linux virtual machines on dedicated x86-64 servers. It is aimed at organizations managing server virtualization, virtual desktop infrastructure, and workloads that need GPU pass-through or GPU virtualization. VM creation and management, disk snapshots, live migration, high availability with restart policies, and resource pools cover the core tasks of a multi-host environment. XenServer also supports Citrix and non-Citrix workloads, with Citrix Virtual Apps and Desktops and Citrix DaaS listed as integrations.
The product is sold through two editions. Premium Edition is intended for production use and includes the premium feature set, CPU-socket subscription licensing, and maintenance. Trial Edition provides almost all Premium Edition functionality for non-production testing for up to 90 days, with a maximum three-host pool. Premium pricing uses a contact-sales model, while the trial gives teams a defined evaluation path before production adoption. The licensing structure is therefore better suited to organizations planning a managed deployment than to individuals seeking a free virtualization platform.
XenServer’s strongest differentiator is its combination of multi-host management and hardware-focused workload support. Windows-based XenCenter provides graphical administration, while the management API and xe command-line interface support automation. Administrators can move workloads between hosts, apply VM restart policies, create snapshots, and exchange images in several formats. GPU support and broad image compatibility add flexibility for virtual desktop and server environments. Teams needing production virtualization with resource pools, live migration, and GPU capabilities should shortlist XenServer; buyers seeking a free plan, desktop-first management across operating systems, or Windows nested virtualization should consider alternatives.
