To use Horizon Composer, you must configure settings that allow Horizon 7 to connect to the Horizon Composer service. Horizon Composer can be installed on its own separate host or on the same host as vCenter Server.
There must be a one-to-one mapping between each Horizon Composer service and vCenter Server instance. A Horizon Composer service can operate with only one vCenter Server instance. A vCenter Server instance can be associated with only one Horizon Composer service.
After the initial Horizon 7 deployment, you can migrate the Horizon Composer service to a new host to support an expanding or changing Horizon 7 deployment. You can edit the initial Horizon Composer settings in Horizon Console, but you must perform additional steps to ensure that the migration succeeds.
- Verify that you created a user in Active Directory with permission to add and remove virtual machines from the Active Directory domain that contains your linked clones. See Create a User Account for Horizon Composer AD Operations.
- Verify that you configured Horizon 7 to connect to vCenter Server. To do so, you must complete the vCenter Server Information page in the Add vCenter Server wizard. See Add vCenter Server Instances to Horizon 7 in Horizon Console.
- Verify that this Horizon Composer service is not already configured to connect to a different vCenter Server instance.
- In Horizon Console, navigate to .
- On the vCenter Server tab, click Add and complete the vCenter Server information on the vCenter Server Settings page, then click Next.
- On the Horizon Composer Settings page, if you are not using Horizon Composer, select Do not use Horizon Composer.
If you select Do not use Horizon Composer, the other Horizon Composer settings become inactive. When you click Next, the Add vCenter Server wizard displays the Storage Settings page.
- If you are using Horizon Composer, select the location of the Horizon Composer host.
Option Description Horizon Composer is installed on the same host as vCenter Server.
- Select Horizon Composer co-installed with the vCenter Server.
- Make sure that the port number is the same as the port that you specified when you installed the Horizon Composer service on vCenter Server. The default port number is 18443.
Horizon Composer is installed on its own separate host.
- Select Standalone Horizon Composer Server.
- In the Horizon Composer server address text box, type the fully qualified domain name (FQDN) of the Horizon Composer host.
- Type the name of the Horizon Composer user.
For example: domain.com\user or email@example.com

What to do next
Configure Horizon Composer domains.
- If the Horizon Composer instance is configured with a signed TLS certificate, and Connection Server trusts the root certificate, the Add vCenter Server wizard displays the Horizon Composer Domains page.
- If the Horizon Composer instance is configured with a default certificate, you must first determine whether to accept the thumbprint of the existing certificate.
