If you encounter issues with a node not starting or immediately stopping after clicking the start button, consider the following checklist and potential solutions:
Common Checks:
1. Image Integrity:
- Verify that the image is not corrupted. Compare the size of the image on your server with the size of the image from the source (e.g., LabHub).
For IOL Images:
1. Generate License File:
- Ensure that the license file is generated. Send #generate_license in this chat to receive instructions on how to generate the license file.
For QEMU Images:
1. Virtualization Support:
- Confirm that virtualization is supported on your system. Send #check-vt in this chat to receive instructions on how to check for virtualization support.
2. Fix Permissions:
- Correct permissions either through the GUI (click the button under "Settings" on PNetLab) or by running the following command in the terminal:
/opt/unetlab/wrappers/unl_wrapper -a fixpermissions
3. Follow the naming conventions:
- Adhere to the naming conventions required for PNetLab to detect imported qcow2 files as VMs. Refer to the conventions outlined here: https://www.eve-ng.net/index.php/documentation/qemu-image-namings/
By following these steps, you can address potential issues related to image integrity, licensing for IOL images, virtualization support for QEMU images, and permissions. If the problem persists after performing these checks and fixes, please let us know.
