Licensing
Citrix XenServer 5.6 Feature Pack 1 uses Citrix standard licensing, and thus
requires only a single web key to activate all features (instead of the dual
licensing scheme used in previous versions).
Dell OEM customers who purchased Essentials for XenServer Enterprise or
Platinum editions, and have installed components from the Essentials range
(e.g. StorageLink, Workload Balancing, Lab Manager, Stage Manager) will be
familiar with redeeming licenses from mycitrix.com and the need for a
Windows-based license server to be present in their environment. You should
return to mycitrix.com and "re-host" their existing license key in order to
obtain an updated key that can be used to license XenServer 5.6
Feature Pack 1. For instructions on how to re-host license keys, see article
CTX118324 How to Return/Re-host a License using My Citrix at
http://support.citrix.com/article/ctx118324.
If you have purchased Essentials for XenServer, but did not redeem their
Essentials license key from My Citrix (using the web key provided by their
OEM) you will need to locate the web key and use it at mycitrix.com. If you
purchased Essentials for XenServer, but are no longer in possession of the web
key, contact your OEM to be issued with a new key.
A licensing server is required to enable the Advanced, Enterprise, or Platinum
features of XenServer. You can download the Citrix Licensing Server from
mycitrix.com, and find documentation on its use at
http://support.citrix.com/proddocs/topic/licensing-1161/lic-licensing-
1161.html.
If you are using the free edition of XenServer, you are unaffected by the new
licensing requirements. Upgrade to the free edition of XenServer 5.6
Feature Pack 1 can take place without deploying a license server.
NOTE: Citrix recommends that customers deploy a license server first, in order to
avoid license-enabled features of XenServer 5.6 Feature Pack 1 becoming disabled
when no license is found.
For further details on licensing, including how to assign a license to a newly
upgraded XenServer host, see the XenServer 5.6 Feature Pack 1 Installation
Guide.
