I have couple question about using Xen in the "real" world.

My test box is a Dell Optiplex 745 with a Core 2 processor and 4 G of
RAM.  I am using 64 bit Centos 5 with Xen 3.03.  Right now I have it
set up so Dom0 is my working domain and I add other DomU for whatever
tests i need to do.  From what I've read here, this is not the best
way to do things.

So my first question is, if I do an install with a minimal Dom0 and
use a DomU for my working domain, can I set it up so that DomU is what
I log on to from runlevel 5?  Is that really the best way to setup a

Next question.  I have a sata DVD/RW drive.  Is there way to get the
DomU's to see it?  I tried the obvious

disk = [ 'file:/xen/xp/carthagexp,hda,w', '/dev/cdrom,hdc:cdrom,r' ]

for an XP install with no luck.  I've also tied /dev/sdc0, /dev/dvd,
and /dev/sdc with no success.  The drive does show up in Dom0.
