Now go to Virtualisation station and create a new VM. Move the *.img file to the location where you want to store your VM. Once downloaded, extract it and you will have a *.qcow2 file. You should be looking for the image with KVM in it, for example **************** Since I still had access through a work related account on the support page of Fortinet, I was able to download a VM image. I wanted to run a Fortigate VM on my QNAP. I hope you can appreciate my research and the effort in writing it down to share. Ok, so I know this post is a bit older, but since I still found it during my google searches, I'm going to try to complement the topic and hopefully provide you with an answer, should in any case you end up on this page.
