Citrix Hypervisor 8 Cloud is available in the following editions:

• Standard Edition
• Premium Edition

The Standard Edition is our entry-level commercial offering.

Customers who have purchased Citrix Virtual Apps or Citrix Virtual Desktops or who use Citrix DaaS (formerly Citrix Virtual Apps and Desktops service) with on-premises desktops and apps have an entitlement to Citrix Hypervisor, which includes all the features listed for Premium Edition.

For more information, see the Citrix Hypervisor Feature Matrix.

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 for Windows or the License Server VPX from Citrix Licensing. Citrix Hypervisor (other than through the Citrix Virtual Apps and Desktops licenses) is licensed on a per-socket basis. Allocation of licenses is managed centrally and enforced by a standalone Citrix License Server (physical or virtual) in the environment. After applying a per socket license, Citrix Hypervisor displays as Citrix Hypervisor Per-Socket Edition.

An unlicensed or Express Edition is not available for Citrix Hypervisor 8 Cloud.

Licensing Citrix Hypervisor

Q: Where can I buy a Citrix Hypervisor license?

A: You can speak to a Citrix representative about buying a Citrix Hypervisor License at http://citrix.com/buy.

Q: How do I apply a Citrix Hypervisor license?

A: Citrix Hypervisor requires a License Server. After licensing Citrix Hypervisor, you are provided with a .LIC license access code. Install this license access code on either:

• A Windows server running the Citrix License Server software
• The Citrix License Server virtual appliance

When you assign a license to a Citrix Hypervisor server, Citrix Hypervisor contacts the specified Citrix License Server and requests a license for the specified servers. If successful, a license is checked out and the License Manager displays information about the license the hosts are licensed under.

For instructions on applying a Citrix Hypervisor license to a Citrix License Server virtual appliance, see CTX200159 – How to Apply a Citrix Hypervisor License File to Citrix License Server Virtual Appliance (CLSVA).

Q: How many licenses do I need to license my resource pool?

A: Citrix Hypervisor is licensed on a per-CPU socket basis. For a pool to be considered licensed, all Citrix Hypervisor servers in the pool must be licensed. Citrix Hypervisor only counts populated CPU sockets.

You can use the Citrix License Server to view the number of available licenses displayed in the License Administration Console Dashboard.

Q: Do I need a per-socket license for sockets that are not populated?

A: No, only populated CPU sockets are counted toward the number of sockets to be licensed.

Q: Do I lose my Virtual Machine (VM) when my license expires?

A: No, you do not lose any VMs or their data.

Q: What happens if I have a licensed pool and the License Server becomes unavailable?

A. If your license has not expired and the License Server is unavailable, you receive a grace period of 30 days at the licensing level that was applied previously.

Q: I am upgrading to Citrix Hypervisor 8 Cloud from a previous Citrix Hypervisor version with a per socket license. Do I have to do anything?

A: No. You can upgrade your hosts to Citrix Hypervisor 8 Cloud Premium Edition using the previously purchased per socket licenses, provided Customer Success Services is valid at least until Mar 16, 2022.

If you have renewed your Customer Success Services after the original purchase, you might need to refresh the license file on the License Server to ensure it displays the Customer Success Services eligibility.

Q: I am moving from an earlier version of Citrix Hypervisor Express Edition (unlicensed) to Citrix Hypervisor 8 Cloud. Do I have to do anything?

A: Yes. You must apply an appropriate license to update your hosts to Citrix Hypervisor 8 Cloud.

An Express Edition is not available for Citrix Hypervisor 8 Cloud.

Q: What license do I need to manage Citrix Hypervisor 8 Cloud updates through the Hypervisor Management service?

A: You must have a valid Citrix Hypervisor license or an entitlement to Citrix Hypervisor through your use of Citrix Virtual Apps, Citrix Virtual Desktops, or Citrix DaaS (formerly Citrix Virtual Apps and Desktops service) with on-premises desktops.

You must also have a subscription to Customer Success Services that is valid on the day you apply an update.

If you have renewed your Customer Success Services after the original purchase, you might need to refresh the license file on the License Server to ensure it displays the Customer Success Services eligibility.

Q: I am a Citrix Virtual Apps and Desktops or Citrix DaaS customer moving from an earlier version of Citrix Hypervisor to Citrix Hypervisor 8 Cloud. Do I have to do anything?

A: No. Citrix Virtual Apps, Citrix Virtual Desktops, or Citrix DaaS customers can update to Citrix Hypervisor 8 Cloud seamlessly. Your existing installed Citrix Virtual Apps or Citrix Virtual Desktops license grants you entitlement to Citrix Hypervisor without requiring any other changes, provided your license is not expired and your Customer Success Services subscription is valid at least until Mar 16, 2022.

Q: I am a Citrix Service Provider licensed for Citrix Virtual Apps and Desktops or Citrix DaaS. Can I use this license for Citrix Hypervisor when I upgrade to Citrix Hypervisor 8 Cloud?

A: Yes. Citrix Hypervisor 8 Cloud supports your license. With this license, you can use all the premium features provided by the Premium Edition of Citrix Hypervisor. To apply this license to your pools, first upgrade or update all hosts within the pool to run Citrix Hypervisor 8 Cloud.

Q: I am a customer with a Citrix DaaS subscription. Am I entitled to use Citrix Hypervisor 8 Cloud?

A: Yes. If you have a Citrix DaaS (formerly Citrix Virtual Apps and Desktops Service) subscription that enables the use of on-premises desktops and apps, you are entitled to use Citrix Hypervisor to host these desktops and apps.

Download a license through the licensing management tool. Install this license on your License Server to use on-premises Citrix Hypervisor with your Citrix DaaS subscription.

With this license you can use all the same premium features as with an on-premises Citrix Virtual Apps and Desktops entitlement. To apply this license to your pools, first upgrade all hosts within the pool to run Citrix Hypervisor 8 Cloud.

Q: What are the constraints on the use of the Citrix Hypervisor Premium Edition advanced virtualization management capabilities delivered as part of Citrix Virtual Apps and Desktops?

A: Every edition of Citrix Virtual Apps and Desktops has access to Citrix Hypervisor Premium Edition advanced virtualization management features. A complete list of all features enabled by a Citrix Virtual Apps or Citrix Virtual Desktops license can be found in the Citrix Hypervisor Feature Matrix.

Citrix Hypervisor entitlements permit virtualization of any infrastructure required to deliver Citrix Virtual Apps or Citrix Virtual Desktops feature components. These features must be accessed exclusively by Citrix Virtual Apps or Citrix Virtual Desktops licensed users or devices.

Extra infrastructure support servers, such as Microsoft domain controllers and SQL servers are also covered by this entitlement, providing they are deployed in the same Citrix Hypervisor resource pool as the Citrix Virtual Apps or Citrix Virtual Desktops infrastructure covered by this license, and providing those support servers are used to support the Citrix Virtual Apps or Citrix Virtual Desktops infrastructure only.

The Citrix Hypervisor entitlement in the Citrix Virtual Apps or Citrix Virtual Desktops license cannot be used for Citrix Hypervisor pools that don’t host Citrix Virtual Apps or Citrix Virtual Desktops infrastructure or Virtual Delivery Agents (VDAs). You also cannot use this entitlement for hosting virtual machines not covered by the permissions above. Citrix Hypervisor must be purchased separately for these uses.

Citrix License Servers

Q: Which License Servers can I use with Citrix Hypervisor?

A: You can use the Citrix License Server software version 11.16 or later on a server running Microsoft Windows, or the Linux-based Citrix License Server virtual appliance version 11.16 or later.

Q: How do I import my license onto the Citrix License Server?

A: For information on importing a license file, see the Licensing documentation.

• Install licenses by using Citrix Licensing Manager

• Import license files by using the Licensing Administration Console

• Install license files by using the command line

Q: Can I run the License Server on my Citrix Hypervisor pool?

A: Yes. You can install the Citrix License Server software on a Windows VM.

Citrix Hypervisor operates with a ‘grace’ license until the License Server is able to boot. This behavior means, after you have licensed the Citrix Hypervisor servers in your pool, and you reboot the host that has the Citrix License Server running on it, a grace period is applied to that host until the License Server is restarted.

Q: Can I use the Windows version of the Citrix License Server with Citrix Hypervisor?

A: Yes.

Q: Can I install Licenses for other Citrix products on a Citrix License Server virtual appliance or on the Citrix License Server software installed on Windows?

A: Yes, you can license other Citrix products by using the Citrix License Server virtual appliance or through the Citrix License Server software installed on Windows. For more information, see Licensing on the Citrix Product Documentation website.

2. Select the Pool or Hosts you would like to license, and then click Assign License.

3. In the Apply License dialog, specify the Edition type to assign to the host, and type the hostname or IP address of the License Server
