Opencloud DaaS Application Server Templates

This section will cover the basics of creating an OVD Application Server template for use in Opencloud DaaS.

Windows Server Template

Pre-requisites/Assumptions

Please consider the following before proceeding:

  1. The Windows Server RD Session Host role is required to install the OVD Application Server service.
  2. If RDS CALs are required, it is recommended to deploy an RDS Licensing server elsewhere in the environemnt.
  3. Current supported versions are Windows Server 2012 R2 With Extended Support, Server 2016, Server 2019, and Server 2022.
  4. Currently, it is only supported to have a template with a single disk.
  5. The system must be sysprepped as the very last step before being converted to a template, so you must use scripts (either locally or initiated via userdata in Opencloud) if it is desired to join the template to an AD domain on instantiation.
  6. This guide assumes you have already configured Opencloud DaaS Provisioning

Deployment Steps

  1. Deploy an instance from the desired Windows Server template or install from an ISO.
  2. Install desired applications, Windows Updates, configure settings as needed.
  3. Install the RDS host server role. This can be done via the Server Manager MMC or Powershell: Install-WindowsFeature RDS-RD-Server
  4. Reboot the VM following the installation of the RDS role.
  5. Downlaod and install the OVD Application Server EXE or MSI (current version: https://archive.inuvika.com/ovd/3.4.2-526da687c5/Inuvika-OVD-3.4.2.7491-ApplicationServer.exe or .msi). Enter the IP or FQDN of your session manager, and reboot after the installation.
  6. NOTE You must make sure the OVD Slave Server Service is running before proceeding sysprep and shutting down the VM.
  7. Run sysprep and shutdown the VM i.e. with %WINDIR%\system32\sysprep\sysprep.exe /generalize /oobe /shutdown
  8. Once the VM is fully powered off, in Opencloud, navigate to Instances > (VM NAME) > Volumes.
  9. Click on the root disk. In the actions pane on the upper right, select the option all the way to the right to "Create Template from volume"
  10. Once the template has been created, log in to the OVD Session Manager Admin Console and navigate to Servers > Unregistered Servers
  11. You can you click the green "Register as Template" button to register your template and adjust further settings accordingly.
