If possible, try installing either 7.3 or 9.0.
From what I've read, many people have had problems with 8.0.
I've done 2 installs with 9.0, and haven't had a single glitch. (and I'm a complete n00b).
I haven't used 7.3, but others have indicated it's one of the more stable of the recent Red Hat releases.
If you're locked into using 8.0, you'll have to get an answer from someone more experienced than myself.
