When I format the new volume for this new domU, I added that -L /
option for the sda2 and /boot for the sda1.

Then, I transferred the files using the dump and restore utilities to
a mounted directory (e.g. /mnt) where:
/mnt => /dev/sda2
/mnt/boot => /dev/sda1

Honestly, I don't know because I don't manage the dom0. But based on
the documentation, it expects sd* mapping.

Right now, the volume is in my other domU's /dev/sdk:
# fdisk -l /dev/sdk
Disk /dev/sdk: 2147 MB, 2147483648 bytes
255 heads, 63 sectors/track, 261 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

/dev/sdk2 18 261 1959930 83 Linux

Based on the above output for the fdisk command, sdk1 contains the
files and directories for the /boot partition while the sdk2 contains
the rest of the files and directories of the entire / partition. With
this, my /etc/fstab for the new domU has been configured like this:
LABEL=/boot /boot ext3 defaults 1 2
LABEL=/ / ext3 defaults 1 1
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
none /proc/xen xenfs defaults 0 0
And I also tried changing the first 2 lines with:
/dev/sda1 /boot ext3 defaults 1 2
/dev/sda2 / ext3 defaults 1 1
Anyway, I just did a grep to this new domU and below were the output:
