> Is this really the reason why the login fails? Does getty not start or does the login fail?
yes, the getty is started
100000 26665 0.0 0.0 6412 792 pts/0 Ss+ 13:22 0:00
/sbin/agetty --noclear tty1

/sbin/agetty --noclear -s console 115200 38400 9600
and i can connect with "fedora1 console"
virsh # console fedora1
Verbunden mit der Domain: fedora1
Escape-Zeichen ist ^]
Fedora release 20 (Heisenbug)
Kernel 3.13.2-2.el6.x86_64 on an x86_64 (tty1)
fedora1 login:
put the console is "crazy". wrong line breaks after hit enter. first
two logins fails with wrong log entries. the password is displayed as
login. the third attemot works. then i have a mix of console and
login promt. every 10 secons i hit enter i see a passwort promt. but i
can still use the shell. but imo this is a other problem. there are
messages about systemd --user can not connect the dbus socket in
/run/user/0/dbus/user_bus_socket
> I've never tested an upstart based distro maybe it is somehow confused. :)
forgot to say the container is fedora 20
> Can you please collect more details why a login via ssh is failing?
set LogLevel to DEBUG3. keyexchange is down. put then hangs for some
time und sshd dies

yes, i know. i have no errors from systemd, all looks fine with "exec
/sbin/init systemd.log_level=debug"
