Loading network images into EVE-NG

All network images obtained from vendors should be uploaded to /opt/unetlab/addons/qemu. EVE-NG support QEMU-based images and Dynamics images, and also iOL (iOS On Linux).

When you get an image from a vendor, you should create a directory inside /opt/unetlab/addons/qemu and upload the image to that directory; then, you should execute this script to fix the permission of the uploaded image:

/opt/unetlab/wrappers/unl_wrapper -a fixpermission
