The App Layering virtual appliance runs on the supported hypervisors listed in this article. The appliance is where you deploy the Enterprise Layer Manager (ELM) during installation.
You can create layers to use on virtually any hypervisor or provisioning software. For the best user experience, publish images to the supported platforms.

Desktop provisioning and application delivery
You can use layered images for Persistent desktops, as long as you do not enable Elastic layering or User layers (Full or Office 365).
To enable User layers or Elastic layers, you must use Non-persistent machines.
Elastic layering does not support View Persona Management.
