Welcome to the documentation for Citrix XenServer (transitioning to Citrix Hypervisor in 2019).
XenServer is the complete server virtualization platform from Citrix. The XenServer package contains all you need to create and manage a deployment of virtual x86 computers running on Xen, the open-source paravirtualizing hypervisor with near-native performance. XenServer is optimized for both Windows and Linux virtual servers.
XenServer runs directly on server hardware without requiring an underlying operating system, which results in an efficient and scalable system. XenServer works by abstracting elements from the physical machine (such as hard drives, resources, and ports) and allocating them to the virtual machines running on it.
A virtual machine (VM) is a computer composed entirely of software that can run its own operating system and applications as if it were a physical computer. A VM behaves exactly like a physical computer and contains its own virtual (software-based) CPU, RAM, hard disk, and NIC.
XenServer lets you create VMs, take VM disk snapshots, and manage VM workloads. For a comprehensive list of major XenServer features, visit www.citrix.com/xenserver.
XenCenter is a Windows GUI client that provides a rich user experience when managing multiple XenServer hosts and resource pools, and the virtual infrastructure associated with them. For more information, see the XenCenter documentation
