In what cases would we want to use this feature? The serial console is
not supported by all guests and I'm not sure it supports multiple
concurrent sessions (does it?), so it's probably not possible to use it
reliably as a replacement for the regular remote shell servers, or even
as an alternative variant.

You probably meant to pass the prompt assist string to remote_login()
but instead you're passing "".
