FortiGate-VM 6.2.3 (EVE-NG on VMware Workstation) Kernel Panic after Installing Evaluation License

Hi Team,

I am facing an issue with my FortiGate VM running in my lab environment and would appreciate any guidance.

Environment:

• FortiGate VM Image: FortiGate-VM64-KVM v6.2.3
• EVE-NG installed on VMware Workstation
• License: Evaluation (Evolution) license installed via GUI

Issue:

The FortiGate VM was working normally before installing the evaluation license. After uploading and applying the license through the GUI, the VM initiated a reboot.

Since then, the VM has been unable to boot successfully. Instead, it continuously crashes with a kernel panic (double fault) during startup and enters a reboot loop.

Below is the console output:

FortiGate-VM64-KVM #
FortiGate-VM64-KVM # Requesting FortiCare Trial license, proxy:(null)

The system is going down NOW !!

Please stand by while rebooting the system.
