There were a few bugs using the --prompt option in virtinst 0.500.0. I'd
recommend either skipping --prompt or updating to virtinst 0.500.1. All prompt
asks you for is really

--name <vmname>
--hvm or --paravirt (for xen only)
--accelerate or not (for kvm only)
--file /path/to/an/image
--file-size #Gb (if the file path doesn't exist)
do you want a url (--location) or cdrom (--cdrom) install ?
install media path

So just fill in the above options and you should be good to go.
