Error

Attempting to create a catalog using an Azure Trusted Launch enabled image results in the following error:

"CreateTerminatingError in operation PreparingMasterImage with message Error starting machine. Security type of VM is not compatible with the security type of attached OS Disk."

Solution

Attached is a sample script ready to use to deploy a Trusted Launch catalog. Please modify the variables and paths throughout the script to match your environment.

Problem Cause

Azure Trusted Launch was not supported in Studio prior to 2206.
https://docs.citrix.com/en-us/citrix-virtual-apps-desktops/2206/whats-new.html#azure-trusted-launch-support

If running CVAD 2203 LTSR, Trusted Launch support is available if the catalog is created manually through the CVAD SDK.
