Hi All,
I have performed an extensive testing of the restore of the data backup image set using my backup and restore scripts.
Two virtual machines, namely, openSUSE 11.2 PV domU, and Slackware64 13.0 HVM domU, did not restore properly.
Please refer to my latest updated restore script for the fixes to these problems.

# exist. The solution to this problem is to simply re-run the above steps again.
