Licensing Overview

Citrix Hypervisor is available in two commercial editions:

  • Standard Edition

Citrix Licensing

Citrix Hypervisor uses the same licensing process as other Citrix products and as such requires a valid license to be installed on a License Server. You can download the License Server from Citrix Licensing. After purchasing the license for your Citrix Hypervisor, you will receive a .LIC license key. This license key should be installed on either:

  • a Windows server running the Citrix License Server software
  • a Linux-based Citrix License Server Virtual Appliance

Important: Citrix Hypervisor 8.0 requires Citrix License Server 11.14 or higher.

When you assign a license to your Citrix Hypervisor host, Citrix Hypervisor contacts the specified Citrix License Server and requests a license for the specified server(s). If successful, a license will be checked out and the License Manager displays information about the license the hosts are licensed under.

When requesting or applying licenses, information about Citrix Hypervisor version and license type may be transmitted to Citrix. No other information relating to any users of the system, virtual machines running in the environment, or the environment in which Citrix Hypervisor is deployed, is collected or transmitted to Citrix. The limited information transmitted to Citrix during the licensing process is handled in accordance with the Citrix privacy policy, a copy of which can be reviewed at .

Licensing Citrix Hypervisor servers

Citrix Hypervisor does not support partial licensing, all hosts in a pool must be licensed. If you are running your Citrix Hypervisor pool with hosts that are licensed with different license types, the host with lowest license determines the features available to all members in the pool. Mixed pools of licensed and unlicensed hosts will behave as if all hosts were unlicensed. For information on managing licenses in Citrix Hypervisor, see Managing Citrix Hypervisor Licenses.

Upgrades to the Premium Edition are available from the Standard edition. For detailed information about Citrix Hypervisor licensing, see Licensing. To upgrade or to buy Citrix Hypervisor license, visit the Citrix website.

License Expiry

XenCenter notifies you when your license is due to expire. You should purchase a license before it expires. When your Citrix Hypervisor license expires:

  • XenCenter License Manager will display the status as Unlicensed.
  • you will no longer be able to access licensed features or receive Citrix Technical Support for any host within the pool until you purchase another license.

License grace period

Citrix licensing has built-in timeout technology. After a startup license is checked out by a Citrix Hypervisor host, Citrix Hypervisor and the License Server exchange “heartbeat” messages every five minutes to indicate to each other that they are still up and running. If your Citrix Hypervisor host cannot contact the License Server, for example, due to problems with the License Server hardware or software or network failures, the server lapses into a 30-day licensing grace period. During the grace period, Citrix Hypervisor licenses itself through cached information and the hosts are allowed to continue operations as if they were still in communication with the License Server. The grace period is 30 days and when the grace period runs out, Citrix Hypervisor reverts to an unlicensed state. After communication is re-established between Citrix Hypervisor and the License Server, the grace period is reset.
