After internalization as described you often (when using different yum versions / libraries on host and guest) you have to remove the DB files.

Yes, I had this problem as well. There is a version step on CentOS (which I cannot name exactly, but existing both in 4x and 5.x) where this failure is produced by local cached rpm packages. To solve this, simply remove th local (guest) cached packages file as well as the DB files by "rm -f /var/lib/rpm/Packages" and "/var/lib/rpm/__db*" followed by the "rpm --rebuilddb". This should solve your problem. Once again as single line for copy & paste:

rm -f /var/lib/rpm/Packages; rm -f /var/lib/rpm/__db*; rpm --rebuilddb
