Hi,
In addition to what has already been posted by kitasupport
Also you need to create a virtual network in order to obtain access so its the first thing that u want to check.
it should works… anyways if the problem persists you can post here the log using -v option (verbose), this will help us to urderstand your problem.
as kitad said, this is only used to copy your pk into the authorized keys file inside the vm, this is all related to ssh.
