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.
