The process for setting the password again is kinda confusing and I
always seem to mess it up.  You need to enter the old password twice,
then the new password twice.

Now, to try to understand the error that you're facing.  First thing,
let me point you to slides that I recently presented at the oVirt
Workshop[1].  

I'm assuming you started with Slide 12 after you booted the image.  You
the progressed until slide 15, but you got an error instead of success
in the bottom-right slide?

If that's the case, then you should see a list of log files to look at.
On that screen, hit F2 and you should get dropped to a shell where you
can do pretty much anything.  To get your log files off, you need to
setup networking and a root password.  Run the following commands and
follow the onscreen menus to setup networking and authentication.  Make
sure to allow ssh password authentication in the ovirt-config-password
script.

1.  # /usr/libexec/ovirt-config-networking
2.  # /usr/libexec/ovirt-config-password

After this is done, you should have networking and can scp the files out
from another machine.  

On a side note, if you can get on IRC (#ovirt on OFTC), it might be
easier for us to debug it only together in real time rather than back
and forth on email.  Feel free to ping me directly.

I haven't hit these errors at all.
