Horizon on VMC – Consideration and setting up a lab environment

A few months back, I setup a Horizon Environment running in our VMC environment used for lab purposes. Since then, I’ve been asked by several people to go through the setup. So, I’ve also decided to create a blog post on the matter.

This blog post will cover the considerations for running VMware Horizon on VMC, and the technical setup itself of the lab environment I created.

Topics covered;

  • Horizon 7 on VMware Cloud on AWS is not DaaS
  • Horizon 7 on VMware Cloud on AWS Deployment Guide and Supportability
  • Feature Support
  • Horizon on VMC architecture
  • Platform Considerations
    • Identity Management
    • File Shares
    • Image management
  • Network Service
    • VMC Network Segments
    • Load Balancing
    • DHCP
  • Firewall Rules
    • Logging
  • Horizon Connection Broker Configuration

VMware Horizon Blast – Failed to Connect to Connection Server

After deploying my latest horizon lab, I hit an issue where I could not hit the login page to authenticate for a Horizon desktop using BLAST, I would be greeted by the following message:

Failed to Connect to Connection Server

I pulled my hair out for a few minutes, before I realised I’ve hit this issue before, and the fix is quite simple.

If the locked.properties file doesn’t exist in the directory C:\Program Files\VMware\VMware View\Server\sslgateway\conf then you must create it!



VDI Cleanup script I use before sealing any golden image before deployment

Below is the VDI Cleanup script that I’ve been using over the years. I thought I’d post this after setting up a Horizon Lab environment. I shared it earlier in the year on Reddit, and had some good suggestions which I used to update the script. The script has been taken from other blogs over the years and just edited further and further for my own/customers needs.

Optimizations to any master are done using the VMware OS Optimization Tool.

I personally just run this as bat file to clean up and shut down the master template as a final step each time I make an update.

You can find the script on Github here, or below.
