[ovirt-users] Non-RHEL RPMs gone after RHV-H upgrade

Hi all We're running RHV 4.1.6. Yesterday I upgraded the RHV-H nodes in our DEV environment to 20180102 and found that all the non-RHEL RPMs are now gone. Their associated config files in /etc are still there. The RPMs in question were from HPE SPP plus a monitoring system client (Xymon). I had thought that non-RHEL RPMs would persist after a host upgrade. Am I wrong on this? Thanks CC
