Incorrect guestOS type for Nested ESXi causes vCLS issues with VMware Cloud Foundation (VCF) Holodeck Toolkit

by // Leave a Comment

Several months back, I started noticing an increase number of folks reporting problems powering on their vSphere Cluster Services (vCLS) VM when using the VMware Cloud Foundation (VCF) Holodeck Toolkit solution and the following workaround can be applied, which came directly from the Holodeck developers.

While a workaround exists including vCLS script located at C:\VLC\VLC-Holo-Site-1\vclsfix, it was very puzzling because this seems to only happen with the Nested ESXi VMs and the VCF Holodeck Toolkit and it was NOT observed when deploying a regular Nested ESXi environment, but I never took a closer look to see why that might be.

A few weeks back, I recieved an email from Mike Foley (former vSphere HA and vCLS PM), I came to learn the reason folks using the VCF Holodeck Toolkit was seeing this problem and it was specific to that solution due to how the guestOS was configured for the Nested ESXi VMs.

Automating deployment of vSAN Data Protection OVA with PowerCLI

vSphere 8.0 Update 3 introduces a new vSAN Data Protection capability for the vSAN Express Storage Architecture (ESA) and it is currently delivered as a standalone VMware OVA (see Duncan's post in case you are wondering where to download) which, once deployed and configures, enables a new vSphere UI plugin as shown in screenshot below.


After going through the manual (vSphere UI) deployment workflow, which also included some non-traditional input like requiring the raw vCenter Server TLS certificate, I was interested in automating the deployment using PowerCLI.

VM snapshot retention-based removal in vSphere 8.0 Update 3

by // 4 Comments

VM snapshots are an extremely useful feature in vSphere but they can also be miss-used and retained for much longer than they should, sometimes weeks, months and even years! Sadly, having a forgotten VM snapshot for a year or longer is not actually as rare as you might expect and I have definitely heard some interesting stories from our field and customers.

While cleaning up a recent VM snapshot, I noticed a new option in the delete all snapshot workflow that now allow users to specify the age of the snapshot to remove which is a new feature in the latest release of vSphere 8.0 Update 3.


This makes it easy for administrators to quickly delete old snapshots without having to write any automation, which is typically how most users manage snapshot retention period including an event-driven approach using the VMware Event Broker Appliance (VEBA) solution.
