A quiet journey through discovery and understanding.

  • OVF Tool Usage

    OVF Tool Usage

    This post documents my first serious experience using the VMware OVF Tool to export and deploy large OVA files outside of browser-based workflows. It covers useful command syntax, locator formatting, network mapping, and practical lessons learned while transferring and deploying a 120 GB appliance into a vCenter environment.

  • Certificate Replacement Errors in VCF Operations

    Certificate Replacement Errors in VCF Operations

    Troubleshooting a failed certificate replacement in VMware Cloud Foundation (VCF) led to deeper log analysis across VCF Operations and Fleet Management appliances. Despite misleading error messages, the root cause was an inactive Microsoft Certificate Authority service due to a CRL issue. Restoring the service resolved the certificate workflow failure.

  • How to Authorize the VCF Operations Fleet Management API

    How to Authorize the VCF Operations Fleet Management API

    This post outlines how to access and authorize the VCF Operations Fleet Management API using Swagger UI. It covers why the API is required, how to reach it, and how to authenticate using Basic Authentication, enabling direct interaction with Fleet Management functions that are not exposed through the UI.

Notes from practice

I use this site to document systems, configurations, and lessons learned as I work through real problems—both professionally and through personal experimentation. The goal is clarity: understand how something works, explain why it behaves the way it does, and make it reliable and repeatable.

These notes are written primarily for myself, but shared openly in case they help someone else avoid a dead end or reduce frustration. If you’d like to learn more, visit the About page.

If you have questions or comments, you’re always welcome to contact me.
