I don't think I will be using the LVM snapshot method. I will simply ensure that my domU is not running, then I proceed to do the losetup and kpartx procedure. Subsequently I will backup the MBR of my domU by dd-ing /dev/loopX and clone all the filesystems of the domU using fsarchiver.
I would like to use fsarchiver because it can support LZMA compression. LZMA can compress better than bzip2 and decompress 3x faster than bzip2. partimage only supports gzip and bzip2.

version of domU storage before doing backup. Either by shutting down
domU, or by creating LVM snapshot first.
Also, if it comes to Windows domUs, I find ntfsclone is better than
fsarchiver. One of the reasons is that fsarchiver can not create
compressed files during restore.
