App Layering

Citrix Hypervisor

To install the App Layering service, you deploy the appliance to a virtual machine in Citrix Hypervisor. If the appliance requires a static IP address, you configure one using the appliance configuration utility. The last section describes next steps.


To start installing App Layering, you need the following:

  • A supported version of Citrix Hypervisor
  • Storage
  • Citrix Hypervisor account and privileges A Citrix Hypervisor account to use for App Layering service. The account must have Citrix Hypervisor privileges to:
    • Create and remove virtual disks.
    • Copy and delete layers on virtual disks by using Citrix Hypervisor file APIs.
  • Citrix Hypervisor software and settings Access to the Citrix Hypervisor Tools to install on the layer.
  • Citrix Hypervisor resource information The Citrix Hypervisor info listed in Citrix Hypervisor Connector Configuration.

  6. Switch to Infrastructure view.

  7. Select your new appliance, which has the name: Citrix Enterprise Layer Manager.

  8. Click Properties, and enter a new name and description for your new appliance. The new virtual machine has 8 GB of memory and 4 CPUs. Take note of the IP address assigned in the Networking tab.

  9. Start Internet Explorer, type the IP address for the new appliance into the address bar and log in as “administrator” with the password “Unidesk1”.

The first time you log onto the appliance you are required to change the App Layering administrator passwords, For details, see Change administrative passwords.

Be sure to install the App Layering Agent, if your environment requires it. See the next section for details.

If you want the appliance to use a Static IP address

You can change the appliance’s IP address and/or its DNS servers. When the appliance is first deployed, the DNS settings are retrieved through DHCP. If DHCP is not available and you will be using static IP addresses, once you select Static, you are prompted to enter the IP addresses for your DNS servers.

  1. Log in to the Appliance Configuration utility. Using either your hypervisor console or SSH, log into the appliance as administrator.

    The first time you log in, use the default password, Unidesk1.

  2. At the Action prompt, enter C (for Configure Networking), and press Return.
  3. At the next prompt, type D for Dynamic (DHCP) or S for Static. If you choose Static, you will be prompted for the IP address and Subnet mask, along with default addresses for the Gateway and DNS addresses.
  4. When prompted, enter Y to save settings.
  5. At the Action prompt, enter Q to quit.
  6. Restart the appliance.
