I might be missing something, but that link seems to talk about FAI and doesn't mention xen. I'm interested in seeing how it can install on the LVM partition but the OS doesn't see it as an entire disk with a partition table. What does "fdisk -l" show, then?
Here is a good link: http://wiki.rpath.com/wiki/Xen_DomU_Guide
The Xen domU or HVM will treat the partition as a whole disk, so that means MBR and stuff, but you can mount it on dom0 as such:
# fdisk -l -u /dev/es_storage/exch_data.1
Disk /dev/es_storage/exch_data.1: 218.2 GB, 218233831424 bytes 255 heads, 63 sectors/track, 26532 cylinders, total 426237952 sectors Units = sectors of 1 * 512 = 512 bytes
Device Boot Start EndBlocks Id System /dev/es_storage/exch_data.1p1 128 426220514 213110193+ 7 HPFS/NTFS
# mount -t ntfs -o loop,offset=128 /dev/es_storage/exch_data.1 /mnt
That will create an auto-loop mount of the partition at sector offset 128.
Oops, offset is in bytes not sectors, so it would be offset 65536 in my case (sector * 512).
