Comment # 1 on bug 1209954 from Johannes Kastl

Addendum:
For non-automatic installations, setting the console and autoyast file via 
--extra-args="autoyast=file:////somename.xml textmode=1 console=ttyS0,115200n8"

is needed, of course. But still, using "--graphics none" results in a
non-working VM.

Addendum 2:
The boot entries from a working and a non-working system are almost the same.
The only differences are
- the UUID of the root partition and
- "console=..." settings if the installation was done using this parameter (see
above)
