Get the drive UUID by using the command vold_id

vol_id /dev/sda1

The string after “ID_FS_UUID=” is the UUID of the drive. Now open your /etc/fstab file and add the following line to the end. Replace the UUID string with your string, your mount point, and customize the other parameters if needed.

UUID=THE-UUID-HERE   /mnt/USBDrive   ext3   user,auto,rw   0   0

To then pass a disk to a xen virtual machine, look at the following lines of the domain config file:

disk        = [
#...root partition and other partitions here...
'phy:/dev/disk/by-uuid/89b976bc-2f66-4b93-abfb-358d6227f8be,sda,w',
'phy:/dev/disk/by-uuid/1871b9a1-8055-4392-8a94-f5407ff37483,sdb,w',
]

basically instead of passing the disk as a /dev/sda1 device, pass it by UUID using the path:

/dev/disk/by-uuid/<the uuid>

Enjoy!
