Well you ought to use ssh keys / agents first. There's nothing
we can do about this in general. The first ssh session there
is for libvirt, the second session is for VNC/SPICE. Since the
password prompt is being done by the ssh client binary, we
can't share the passwords across the sessions

If we used libssh2 however it would be possible to avoid the
double password prompts
