If you have used a key that is supposedly "fixed" or generated, but it still fails, consider the following:

However, once those 60 days expire, the environment stops operating normally. Virtual machines cannot be powered on, vCenter integration fails, and the host enters a "disconnected" state. If you're running a VCF (VMware Cloud Foundation) environment, evaluation license expiration can create a particularly nasty circular dependency: hosts need licenses to power on management VMs, but the VCF Operations appliance must be running to assign those licenses.

Assign a license with larger capacity, upgrade the license edition to match the resources and features on the host, or deactivate the features that do not match the license edition.

Remember that free keys cannot be added to a vCenter server. If you are using vCenter, you must use a paid subscription license.

New keys are now issued based on a metric rather than per-CPU: Free ESXi: Restrictions and Limitations - NAKIVO

An ESXi license key is strictly tied to a specific major version. A license key generated for will not work on an ESXi 8.0 host. If you upgrade your environment, you must log into your Broadcom Customer Support Portal to upgrade your license keys accordingly. 2. Capacity Exceedance

You cannot use old, "fixed" keys for new software. You must upgrade your license entitlement in the Broadcom support portal to receive a compatible key for the new version. Issue C: No Keys Available (Air-Gapped Environments)

$licenseData = New-Object VMware.VimAutomation.License.Types.LicenseData $licenseKeyEntry = New-Object Vmware.VimAutomation.License.Types.LicenseKeyEntry $licenseKeyEntry.TypeId = "vmware-vsphere" $licenseKeyEntry.LicenseKey = "XXXXX-XXXXX-XXXXX-XXXXX-XXXXX" $licenseData.LicenseKeys += $licenseKeyEntry

For hosts managed by vCenter, you can license multiple hosts at once using the vSphere Client's license management function. The hosts must be connected to the vCenter Server system.

Since February 2024, VMware has transitioned from perpetual (one-time buy) keys to a . While existing "fixed" perpetual keys continue to function, they no longer receive support or updates once their original Support and Subscription (SnS) contracts expire. 1. Key Status: Perpetual vs. Subscription

To avoid common issues and ensure smooth operation, follow these best practices for managing ESXi license keys:

Error: "The license key entered cannot be used on this host"

Broadcom has transitioned VMware vSphere and ESXi to a .

VMware still offers a free ESXi hypervisor (up to version 8, though registration may require a Broadcom account post-acquisition).
