[Users] oVirt and AWS

Hi Guys, Hope you are all well. I am currently putting together a test rig to use this software in my company for VM maanagement. I am using AWS to host this at the moment. I am having trouble adding a new host. When I enter the details and click ok I recieved an error telling me I cannot add host. Failed to create SSH...... If anybody has managed to succesfully configure this on AWS and/or provide some pointers would be much appreciated. Many thanks folks! Jamie
