I found RH Satellite 6.5 is General Available.
Started the update, see if I will encounter issues.
1. cvmanager does not work anymore.
1.1 Has been reported in the issue list of the github project.
1.2 Opened a RfE to get it supported by Red Hat, so cvmanager gets in line with RH Satellite updates.
2. RHEL 8 KVM guests clients do not get correct Subscription when you have VDC subscriptions. Opened a support case.
2.1 There seems to be an issue with virt-who on RHEL 7.6 not reporting RHEL 8 guests.
