Proposed updates for RHVH
Why RHV manager proposes updates of host to next version?
I have RHV 4.1 installation and want to keep it at 4.1.x releases for some time before upgrade to 4.2, but manager shows me that there are newer versions of hypervisor and that version is 4.2. I have bad experience upgrading host from 4.0 to 4.1 and thatn VMs won't start anymore after restart or shutdown.
That's honestly a question I'm asking myself since in contrast to the RHVM repositories the RHVH repository is not labelled for one particular version of RHV, let's say 4.1 or 4.2. I did almost run into issues since I updated a test machine and bumped it from 4.1 to 4.2 but the manager was still on 4.1. Luckily for the small workloads and the small setup the host came up and continued to work, but there is no such document as to how or if we can actually limit the version of a RHVH system. (I don't think subscription-manager would be the right since both some late RHVH 4.1 and the current 4.2 images are based on RHEL 7.5)
The only workaround which I honestly don't think is so great, would be to not RHSM repos but keep a local mirror where you'd keep snapshots of versions you want to upgrade to.
