Option C: VMUG Advantage (For Learning & Testing)

For IT professionals who need a fixed license for learning, VMware User Group (VMUG) Advantage provides 365-day keys for all VMware products for ~$200/year.

These are not permanent, but you can renew them annually.
It’s a legal, low-cost way to get a fully functional environment.

Step 1: Access Your ESXi Host

14. Summary recommendations

Manage ESXi licensing centrally via vCenter.
Ensure host configuration persistence and correct automation practices.
Keep a mapped inventory of license keys and enforce change control.
Use logs and the CLI for authoritative state verification and to diagnose reversion causes.
When in doubt or if behavior contradicts supported workflows, escalate to VMware Support with logs and evidence.

If you want, I can:

Provide exact CLI commands tailored to your ESXi and vCenter versions (tell me versions), or
Draft a step-by-step script (PowerCLI or shell) to detect and fix hosts that are reverting license keys across a cluster.

Error 3: “Evaluation mode expired. Some features disabled.”

Fix: You must assign a paid or free license. The 60-day grace period is over; there is no “extension” trick anymore.

5. Step-by-step troubleshooting (practical)

Follow this ordered approach; stop when issue resolved. vmware esxi license key fixed

Confirm where license is managed
- If host is managed by vCenter, check vCenter > Licensing > Assets > Hosts for assignment. If license is assigned there, change it in vCenter (not only host client).
Attempt a controlled reapply
- In vCenter: remove current key assignment from host, add the desired key to inventory, then assign it to the host. Wait a few minutes and check host UI and hostd logs.
Check for automation/config policies
- Inspect host profiles, Auto Deploy, and configuration management systems to see if they contain license assignment steps. If so, update those to the desired key.
Verify privileges and path
- Ensure the user/account making change has license and Host/Global privileges. For scripted changes, confirm which credentials run the script.
Check host persistence
- Ensure ESXi host has a valid scratch location and not running with temporary RAMdisk-only state. Use esxcli system settings advanced list or review DCUI for scratch config. If scratch partition is missing, create or reconfigure persistent scratch.
Use command line to show and set license Treatise on "VMware ESXi License Key Fixed" Example
- Show: esxcli software license list or vim-cmd vimsvc/license --show
- Set: vim-cmd vimsvc/license --set
- Check result and logs.
Reboot test
- After reapply, reboot host (during scheduled maintenance) to verify the assignment persists.
Inspect vpxd and hostd logs for reconciliation events
- Look for entries indicating vCenter overwrote license or refused change; this indicates vCenter-side enforcement.
Check license consumption and entitlements Option C: VMUG Advantage (For Learning & Testing)
- In vSphere Licensing, confirm the key is valid for ESXi and not consumed elsewhere or expired. For evaluation expiration, apply a proper permanent key.
If configuration is corrupted

Consider backing up host configuration (vicfg-cfgbackup or host profile export), then attempt to rebuild scratch or repair config. In severe cases, reinstall ESXi and restore configuration, ensuring correct license is applied after re‑import.

If a bug is suspected

Search VMware KB for your exact ESXi and vCenter versions and “license” issues. If matched, apply recommended patch or workaround.

Contact VMware support

If the license cannot be changed by supported mechanisms, open a support request, providing logs and evidence collected.
