| Problem | Likely Cause | Potential Solution | | :--- | :--- | :--- | | | Incorrect file permissions on the image or directory after upload. | Run the permission fix script: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions . | | The appliance fails to boot (stuck at boot screen). | The image file may need to be converted to a different format, or it may be corrupted/incomplete. | Ensure you have the correct image. If you have a .vmdk , try converting it to qcow2 using qemu-img . | | The node starts but console is unresponsive. | The console settings (e.g., baud rate, telnet vs. VNC) in the node template may be incorrect. | Check the node's configuration in the emulator. For most Cisco virtual routers, the default is telnet. | | The MAC address seems to change or the config is lost on reboot. | The node may be configured to use a snapshot or may not have a persistent virtual disk. | In GNS3 or EVE-NG, ensure the virtual disk is set to be persistent and not a snapshot. The IOSv image expects a separate startup config file ( IOSv_startup_config.img ). |
