Connector Configuration & Optional Script (VMware Horizon View for vSphere)

In this article:

Before you start

Create a Connector Configuration

Script Configuration (Optional, Advanced feature)

A VMware Horizon for vSphere Connector Configuration contains the credentials and storage location Unidesk needs to publish Layered Images to VMware Horizon View in your vSphere environment.

You can publish Layered Images to be used in any of the following pools:

A Horizon View Composer Linked Clone Desktop Pool.
A Horizon View Instant Clone Desktop Pool.

In the Connector Configuration wizard, be sure to configure a Virtual Machine Template, so that the Layered Image you publish will be in a ready-to-use VM, the image shut down and a snapshot taken. You can use the VM in your Horizon environment without further modifications. For example, if you are publishing a Layered Image to a Linked Clone Desktop Pool, the Layered Image becomes a 'Parent VM' that you can select for your Linked Clones pool.

Each Connector Configuration is set to publish Layered Images to a specific storage location in your vSphere environment, so you may need more than one VMware Horizon Connector Configuration if publishing to multiple locations. Further, you may want to publish each Layered Image to a location convenient to the systems you will be provisioning with the published image. For more about Connectors, and Connector Configurations, see Connector essentials.

Notes:

This Connector Configuration is for publishing Layered Images only. (You cannot package Layers using this connector.)
Personal vDisks are not supported for View. The published desktop images will be non-persistent. Currently, vDisks can only be used when publishing to Citrix PVS.
When installing the Horizon Agent on the VM, select the custom setup option as follows:
- Select the VMware Horizon View Composer Agent option when deploying View Composer linked-clone desktops.
- Select the VMware Horizon Instant Clone Agent option when deploying instant-clone desktops.

Before you start

The first time you create an Image Template for publishing Layered Images to a location in your Horizon environment, you will create a Connector Configuration for that location.

Required information for this Connector Configuration

The Connector Configuration wizard let's you browse for the vCenter Server, Data Store, and Host to use for a new configuration.

Important: The fields are case sensitive, so any values that you enter manually must match the case of the object your environment, or the validation will fail.

Name - A useful name to help identify and keep track of this connector configuration.
vCenter Server - The name of the vSphere server with which the Unidesk ELM will integrate.
vCenter User Name - The user name of the account that the Unidesk ELM will use to connect to vSphere.
vCenter Password - The password of the account that the Unidesk ELM will use to connect to vSphere.
DataCenter Name - The name of the vSphere DataCenter in which the Unidesk ELM will create and retrieve virtual machines.
Virtual Machine Template (recommended) - The VM to use as a template for cloning. Use the template to create a VM with the hardware settings for View, including memory, CPUs and video settings. You can specify the host, datastore and network for configuring the resulting VMs. The VM must not have any connected disks.
DataStore Name - The name of the vSphere DataStore in which the Unidesk ELM will create and retrieve virtual machines.
ESX Host Name - The name of the vSphere ESX Host on which the Unidesk ELM will create and retrieve virtual machines.
Network Name - The name of the vSphere Network in which the Unidesk ELM will create and retrieve virtual machines.
Virtual Machine Folder Name - The name of the vSphere Folder in which the Unidesk ELM will create and retrieve virtual machines.

To enter values:

The first three vCenter fields must be entered manually. Once the credentials in those fields are validated, you can select values for the remaining fields from drop-down menus.
To enter values manually: Click to put the cursor in the field and type the value.
To select a value from a drop-down list: Click once to put the cursor in the field, and a second time to choose from a list of possible values.

To add a new Connector Configuration:

On the wizard for creating a Layer or for adding a Layer Version, click the Connector tab.
Below the list of Connector Configurations, click the New button. This opens a small dialog box.
Select the Connector Type for the platform and location where you are creating the Layer or publishing the image. Then click New to open the Connector Configuration page.
Enter the configuration Name, and the vCenter Server, vCenter User Name, and vCenter Password). For guidance, see the above field definitions.
Click the CHECK CREDENTIALS button below the vCenter fields. The DataCenter field is then enabled with a list of DataCenters available.
Select the DataCenter, and the remaining dropdowns will be enabled.
(Recommended) Select a virtual machine to use as the template. Although a VM Template is optional, it is strongly recommended.
Complete the remaining fields and click the TEST button to verify that Unidesk can access the location specified using the credentials supplied.
Click Save. The new Connector Configuration should now be listed on the Connector page.

Script Configuration (Optional, Advanced feature)

When creating a new Connector Configuration, you can configure an optional Powershell script on any Windows machine running a Unidesk Agent. These scripts must be stored on the same machine that the Unidesk Agent is installed on, and will only be executed after a successful deployment of a Layered Image. Some preset variables are available to enable scripts to be reusable with different template images and different connector configurations. These variables will also contain information needed to identify the virtual machine created as part of the published layered image in vSphere.

Execution of these scripts will not affect the outcome of the publish job, and progress of commands executed in the script will not be visible. The vSphere connector logs will contain the output of the executed script.

Configure a Script (Remember, this is optional)

If you want a script to run each time a Layered Image is published, complete these steps using the values described in the sections that follow.

Complete and save the Connector Configuration as described above.

Note: Before selecting Script Configuration page, you must save (or discard) any edits to the Connector Configuration settings,
If the Navigation menu on the left is not open, select it and click Script Configuration to open the Script Path page.
Complete the required fields using the values detailed herein, and click Save.

Script Configuration fields

Enable script - Select this check box to enable the remaining fields. This allows you to enter a script that will be executed each time a Layered Image is published.
Script Agent - The agent machine where the scripts will be located and executed from.
Username (optional) - The username to impersonate when running the script. This can be used to ensure the script runs in the context of a user that has the needed rights/permissions to perform the operations in the script.
Password (optional) - The password for the specified username.
Path - A full path and filename on the agent machine where the script file resides.

Other Script Configuration values

Powershell variables

When the script is executed the following variables will be set and can be used in the powershell script:

Value	Applies to connector types:	Value determined by which code:	Description
connectorCfgName	All	Common code	This is the name of the connector configuration that the script configuration is associated with.
imageName	All	Common code	This is the name of the layered image template that was used to build/publish the layered image.
osType	All	Common code	This is the OS type of the layered image that was published. It can be one of the following values: Windows7 Windows764 Windows200864 Windows201264 Windows10 Windows1064
virtualInfrastructureServer	All	vSphere connector code	The vCenter server specified in the connector configuration.
vmName	All	vSphere connector code	The name of the virtual machine that was created.
vmId	All	vSphere connector code	The virtual machine ID taken from the mobref of the vm (i.e. "vm-12345")
vmUuid	All	vSphere connector code	The virtual machine UUID as set by the underlying highbrd.

User Impersonation

The Unidesk Agent, which runs as a service on a Windows machine, runs under either the local system account or the network account. Either of these accounts may have some special privileges, but they often are restricted when it comes to executing specific commands or seeing files in the file system. Therefore, Unidesk gives you the option of adding a domain user and password that can be used to "impersonate" a user. This means that the script can be executed as if that user had logged onto the system so that any commands or data will be accessible subject to those user rights and permissions. If no user name or password is entered, the script executes using the account under which the service is configured to run.

Script Execution Policy

Script execution policy requirements are generally up to you. If you intend to run unsigned scripts, you must configure the execution policy to one of the more lenient policies. However, if you sign your own scripts accordingly, you can choose to use a more restrictive execution policy.
