App Volumes Apps On Demand – Certificate Issue

January 19, 2023

Horizon Suite 2212 is GA since last week and of course I already upgraded all my lab with this new release.

I was particularly interested by the Application on Demand so directly manage App Volumes application on RDS with all entitlement done within the Horizon Console.

The principle consist of adding App Volumes server in Horizon and then assign it to an “Automated” farm.

Now when you add you App Volumes Server into Horizon, you’ll certainly need to import App Volumes certificates into the “Trusted Root Certification Authorities” folder and then restart Horizon Services on all you Connection Servers.

Now even if doing that, you can encounter the following issue, with Enterprise signed certificate :

I had this issue on my lab, so to get it solved, I had to generate a new certificate for my App Volumes server using a new Template.

This is how to do it ….

PowerShell : Automatically Expand Writable Volumes

September 9, 2022

One of my customer raised an issue about managing writable volumes as they are mainly used by developers who are unable to restrain their desires to fill disk with tons of data and can’t do some clean up 🙂

The problem of course is that the writable volume grow up to no free space and unfortunately the user is not aware of that as the “ReportSystemFreeSpace” Reg Key works only for App Volumes 2.x and not App Volumes 4.x

The following script can be used manually or integrated with Task Scheduler but requires App Volumes Server 2206 (4.7) to handle “requested_mb” parameters. You can use it with previous version but you don’t know if a request to expand disk was previously initiated.

Disclaimer : The script it self is not supported by me or VMware so use it at your own risk however it’s using official VMware API for App Volumes, and thank to Chris Halstead as his initial script helped me a lot (https://github.com/chrisdhalstead/appvolumes-expand-wv)

AppVolumes 2103 (4.4) Tools – Off line packaging for both AppVolumes On-Prem and on Azure

March 26, 2021

One of the great update from AppVolumes 2103 (aka 4.4) is now you can install only App Volumes Tools and package applications offline from a simple VM on VMware Workstation for example and produce the same package for App Volumes on Prem (.vmdk file) and for App Volumes on Azure (.vhd files). So exactly the same package for both environment.

So let me describe how I created my “Capture and Build” VM, how to capture and import your applications….

App Volumes, load balancer health check

April 17, 2020

I recently had an issue with one of my App Volumes server: even if my server was down in an App Volumes point of view (connection lost the database), my Kemp load balancer see it up and running because: the web interface was up and favicon.ico was also available.

The template for App Volumes (part of Horizon 7 Template) is, in my opinion not complete and it missed the right way to configure health check

So the right way to configure load balancer ‘s health check is the following :
