Yeah, I'm not familiar with serial consoles and I'm remote to the
servers. We do have iLO cards in the servers where I can take over the
servers console. In these cases where the server has problems, it's a
black screen and you can't do anything.

Yeah, tried both of these when I tried XenServer 5.5 and had no success
with either of them. At the time, a couple months ago, I did a lot of
searching for answers and it seemed that a lot of people were having
similar problems. 

Thanks,
