Yes, if you install libvirt-cim-0.6.1-4.el6 (which is the version in RHEL6.4), PG_InterOp would get installed as well.
Since upstream commit 07adabc, the providers registered on installation are only unregistered on uninstall, not update.
Commit 19ffef8 only fixed this for uninstall -> install, where PG_InterOp gets unregistered by the old package (without this commit) and the new package (with the commit) doesn't register it.
On upgrade, the old package leaves it behind.
yes, confirm. some verification steps: 1. for old package it can clean the PG_InterOp as we seen # rpm -ivh libvirt-cim-0.6.1-4.el6_4.1.x86_64.rpm Preparing... ########################################### [100%] 1:libvirt-cim ########################################### [100%] [ OK ] down CIM server: [ OK ] Starting up CIM server: [ OK ] # ls /var/lib/sfcb/registration/repository/root/ cimv2 interop PG_InterOp virt # rpm -e libvirt-cim Deleting registered classes in libvirt-cim.

So we should keep the clean script for PG_InterOp.
