Hi,

Thanks for your answer but virt-viewer reacts the same way.  If I use 
the line you mention I get asked for a password again and again.

I get the following in the system logs though:

==> /var/log/auth.log <==
Jun 22 21:35:06 phoenix sshd[23876]: Accepted password for root from 
x.x.x.x port 55720 ssh2
Jun 22 21:35:06 phoenix sshd[23876]: pam_unix(sshd:session): session 
opened for user root by (uid=0)
Jun 22 21:35:07 phoenix sshd[23876]: Received disconnect from x.x.x.x: 
11: disconnected by user
Jun 22 21:35:07 phoenix sshd[23876]: pam_unix(sshd:session): session 
closed for user root

Would you know of a way to get a running debian OS without the use of a 
console?

Many thanks for your help!
