Ok, so the summary seems to be that images are ok for small stuff (and

Right
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.
Xen doesn't do any partitioning. I suppose it would be possible to
create a LV and then partition that block device up more (like you would
a hard drive) but I think it is more common to create an LV for each
partition you need and just attach it to the Xen vm in the xen config.
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?
If you are using a cd based install I think you will have to do HVM for
the installer to work right. So you might need a line more like
'phy:/dev/xenhost-lvm/winxp,ioemu:hda,w'
thats from my winxp guest but you can change it up for what suites your
needs.
Of course I could be wrong on that assumption.
