Ok, so the summary seems to be that images are ok for small stuff (and tinkering) but I really want to partition it out (I assume this becomes stronger as the partition grows).  RAID 5 may or may not be a good idea.

My assumption (correct me here) is that the partition/logical volume I create for the Xen domU looks like a disk?  Then, Xen will partition that disk out -- and I will create swap, /boot, /, etc partitions.

Now, to continue on the beginner topics.  Using my existing RAID volume + LVM, I created a logical volume for a file server. I've specified it as:

disk = [ "phy:lvm-raid/FileVolGroup,sda1,w" ]

But, apparantly the installer doesn't see it?  What am I missing?  I've tried it as /dev/lvm-raid/FileVolGroup.  I can mount it in dom0 (and then umount it of course).  I saw a description where they formatted it, so I tried that and it still isn't seen.  Do I need to go at it via the /dev/mapper/lvm--raid-FileVolGroup?  Something else?

This has gotta be basic, so basic I'm not finding anything.  :-p
