When using the 'ssh://' scheme, libvirt expects that you have configured
an SSH agent and publickeys to provide seemlessly non-interactive auth.

virsh opens a single SSH connection, but virt-manager will open multiple
connections if you have a domain VNC/SPICE console open.

With libssh/libss2 we ought to be able to prompt for the password
interactively IIUC.
