vSphere 9.0 were officially released on June 17, 2025 . Following Broadcom's acquisition of VMware, the platform underwent a radical transformation in how it is licensed and managed. Key Licensing Changes in Version 9.0
The most significant change in vSphere 9.0 is the complete retirement of traditional 25-character license keys in favor of a subscription-based model. Automated Licensing
: Starting with version 9.0, product components are licensed automatically through a connected vCenter instance. Removal of Manual Entry
: The functionality to manually license individual hosts via the VMware Host Client has been removed. Subscription Files
: Standard license keys are replaced by subscription-based license files or objects that span a specified capacity (typically measured in cores). VCF Operations Requirement
: To manage version 9.0 licensing, environments typically require an installed and registered instance of VMware Cloud Foundation (VCF) Operations New Features in ESXi 9.0 vmware esxi 9 license key github extra quality
Version 9.0 focuses on modernizing hardware support and streamlining lifecycle management: Virtual Hardware Version 22 : Supports massive virtual machines with up to 24 TB of RAM
, specifically designed for AI and heavy-duty database workloads. Memory Tiering : Productionizes the ability to use NVMe devices
as tiered memory, allowing for expanded memory capacity beyond physical RAM limits. Live Patching Enhancements
: Expanded coverage for patching the vmkernel and other components without requiring maintenance mode or VM evacuation. Trusted Domain Extensions
: Provides a hardware-based execution environment to safeguard sensitive data within virtual machines. Storage Upgrades : Includes support for NVMe over Fabrics (TCP and FC) boot disks. Warning Regarding Unofficial Sources Searching for "license keys" on platforms like vSphere 9
or sites claiming "extra quality" is highly discouraged for several reasons: Technical Incompatibility
: Version 9.0 does not use legacy license keys; it requires a connection to a licensed vCenter 9.0 and VCF Operations. Security Risks
: Unofficial "activators" or keys from third-party repositories often contain malware or backdoors that can compromise your entire infrastructure. End of Free Version
: Broadcom discontinued the free version of ESXi (formerly the "Free vSphere Hypervisor") in February 2024.
For home labs or testing, the recommended legitimate path is a VMUG Advantage The End of Free ESXi
