VMware ESXi: Applying a Fixed (Perpetual) License Key Guide

This guide covers assigning a perpetual, non-expiring license to an ESXi host. These licenses are typically purchased through VMware (now Broadcom) or an authorized partner. Unlike evaluation or subscription licenses, fixed licenses do not expire but are limited to a specific version (e.g., vSphere 7, 8).

If your ESXi license has expired or is invalid, you must apply a new key to restore functionality. Note that if the license for ESXi expires, you may be unable to start vCenter, requiring you to access the host directly. Step-by-Step License Application

"Fixing" the license key usually refers to overcoming common issues when transitioning to the new model or upgrading from older versions. Removing Stale Licenses:

• A host profile, Auto Deploy image, or personalization script sets/overrides license on boot.
• Desired state configs from automation tools (e.g., Ansible, Salt, Puppet, PowerCLI scripts) reapply a key.
