Screen shot showing VM in GUI I wish to add a USB drive as hard disk for VM to boot off which needs to be done via command line.

Thanks

Don't use sudo for the command. This switches to the root user instead of your normal user.
The root user doesn't know about the VMs of your normal user.

Thanks - Solved
