Lab 5: Horizon Linux Desktop Pool deployment (Easy Setup Tool)

Up until recently, the process for Deploying Linux Desktop Pools has been fairly challenging, We will be using the new Easy Install Setup tool for Horizon Linux Desktops

We will complete the following tasks

Prepare Linux, copy and extract the Horizon Agent
Install the Horizon Agents using the Easy Install tool
Take a vSphere snapshot of the VM
Create an Instant Clone Pool
Test a desktop pool session
