Managing Licenses in XenServer v6.2.0

Jul 02, 2013

This topic contains information about managing licenses in XenServer version 6.2.0. For information about managing licenses prior to XenServer 6.2.0, see Managing Licenses in XenServer 6.1.0 and earlier.

When you install XenServer it starts in an unlicensed state. When it is unlicensed, there are no restrictions on its functionality or features, with the exception of the application of hotfixes. In order to receive Citrix Support, XenServer hosts must be licensed.

XenServer hosts are licensed on a per-populated socket basis and all hosts in a pool must be licensed. Mixed pools of licensed and unlicensed hosts will behave as if all hosts were unlicensed.

To assign a XenServer license

  1. On the Tools menu, click License Manager.
  2. Select the host(s) or pool(s) that you wish to assign a license and then click Assign License.
  3. In the Apply License dialog, select the type of license you want to request from the license server:
    • Citrix XenServer Per-Socket: Select this option to activate the per-populated socket licensing model. This license type is applicable for XenServer version 6.2.0 and higher.
    • Citrix XenServer for XenDesktop: Select this option to request an existing Citrix XenServer for XenDesktop license from the license server.
  4. Enter the license server details and then click OK.
    Note: By default, the License Server uses port 27000 for communication with Citrix products. If you changed the default port on the License Server, enter the appropriate number in the Port number box. For more information about changing port numbers due to conflicts, see the Licensing Your Product topic on Citrix eDocs.

XenCenter contacts the specified Citrix V6 license server and requests a license for the specified server(s). If successful, a license is checked out and the information shown in the XenCenter License Manager will be updated. If the license server cannot be contacted, then the server lapses into a 30-day licensing grace period.

Note: When requesting or applying licenses, information about the XenServer 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 XenServer 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 http://www.citrix.com/privacy.

Upgrading to XenServer 6.2.0 from the Free edition

After upgrading to XenServer 6.2.0 host or pool from the Free edition, you will have an unlicensed, but fully functional edition of XenServer. However, XenCenter displays its status as Unsupported and you will be unable to apply hotfixes or other updates using XenCenter. If you choose to purchase a license, as soon as you assign the host or pool a new license, its status will display as Licensed, and the License Type will show as Citrix XenServer Per-Socket Edition.

Upgrading to XenServer 6.2.0 from either an Advanced, Enterprise, or Platinum Edition

After upgrading to XenServer 6.2.0 host or pool from a paid-for edition, you will have an unlicensed, but fully functional edition of XenServer. However, XenCenter displays its status as Unsupported and you will be unable to apply hotfixes or updates using XenCenter. In such cases, you will need to:

  1. Trade-in your existing per-host license for a per-socket license
  2. Add the new license file to your License Server
  3. Apply the license to your XenServer host or pool

After applying the license, your host or pool will display as Licensed, and the License Type will show as Citrix XenServer Per-Socket Edition.

To release a XenServer license

  1. On the Tools menu, click License Manager.
  2. Select the host(s) or pool(s) and then click Release License.
