Connecting firewall to GNS3

Aloha,

I have been attempting to deploy a Cisco firewall to my GNS3 environment. I currently have a virtual box, Oracle machine, deployed on my laptop. I tried pointing my GNS3 to the Oracle virtual box and deployed the ASA to GNS3 using a real ASA image, but that doesn’t work. Is there a way to deploy a Cisco ASA firewall to GNS3 using a virtual box on the laptop that I use to run GNS3, or do I have to use a standalone ESXi hosts machine as my virtual server?
