Hi,
the formatting has gone wrong, but that doesn't matter. The auth you are
supplying is for libvirt authentication (might not be required as you
use ssh to root) and the password you are being asked for is needed for
the ssh connection. You can either create ssh keys for password-less
connection or use other type of transport (uri
qemu://192.168.1.203/system which defaults to qemu+tls or
qemu+tcp://192.168.1.203/system). For setting up the other transports
you can have a look at docs or web pages.
