When working with VMware Horizon View, a common use for a base layer is to perform OS upgrades on our existing Horizon View full-clone desktops. As such, the target desktop for our base layer capture should be configured similar to the virtual desktop master image that we use with Horizon View.

Volume Shadow Copy Service
Microsoft Software Shadow Copy Provider
In order to capture a Mirage base layer, the target desktop must be connected to our domain, have the Mirage client installed, and be registered with our Mirage server. The desktop should be displayed in the Mirage console's Pending Devices window by going to VMware Mirage | VMware Mirage System | Inventory, as shown in the following screenshot:
