I personally consider the fact that you gave up on 4.3/CentOS7 before CentOS 8 could have
even been remotely reliable to run "a free open-source virtualization solution for
your entire enterprise", a rather violent break of trust.
I understand Redhat's motivation with Python 2/3 etc., but users just don't.
Please just try for a minute to view this from a user's perspective.
With CentOS 7 supported until 2024, we naturally expect the added value on top via oVirt
to persist just as long.
And with CentOS 8 support lasting until the end of this year, oVirt 4.4 can't be
considered "Petrus" or a rock to build on.
Most of us run oVirt simply because we are most interested in the VMs it runs (tenants
paying rent).
We're not interested in keeping oVirt itself stable and from failing after any update
to the house of cards.
And yes, by now I am sorry to have chosen oVirt at all, finding that 4.3 was abandonend
before 4.4 or the CentOS 8 below was even stable and long before the base OS ran out of
support.
To the users out there oVirt is a platform, a tool, not a means to itself.
