Description of problem:

I boot the guest and it does never reaches the welcome screen.
The 'unknown error' screen is shown, but it later get covered by
the black screen and it is no longer possible to report the issue
via abrt.

Booting F18b TC6 on the very same guest works ok, one can reach
the welcome screen. With F18b TC7 one does not reach the welcome

Version-Release number of selected component (if applicable):
F18b TC7

How reproducible:

Steps to Reproduce:
1. boot F18b TC7
2. unknown error and black screen

Actual results:
F18b TC7 not reaching the welcome screen
F18b TC6 reaches the welcome screen

Expected results:
to reach the welcome screen (at least)

Additional info:
It is not possible to use ABRT due to it being covered by
a black screen after some seconds.
