Thanks for your help with the config change, Itamar
So am I correct that the config change is to be made in the serverCPUList
setting?
May I please request the proper format of the configuration lines, and
clear documentation of how to apply this workaround?
Perhaps we can collect our older processors into some "other" supported but
not "known or proper or whatever" models. Your system can give us a warning
for attempting an unexpected processor, but hosts are allowed to run. Isn't
it obvious that an older processor may provide lesser capability compared
to a newer one?
I'm installing on this hardware to gain experience with ovirt. and put a
lab server together to test a roadmap to HA. I understand that i may not be
the targeted audience, and you may not support all hardware..
Respectfully to the developers, in my opinion I don't have an arbitrary set
of cpu flags, I have two xeon 5060 "dempsey" processors which have been
visualization workhorses for years. They are well known have a standard set
of "flags" happily run about every known operating system and visualization
environment except Ovirt at this point. Having stumbled on this limitation,
and having spent hours trying to figure it out, it could be considered
arbitrary that my processor didn't work without warning. Respectfully I
think think it is most appropriate that the system allows my processor to
run hosts and if it is not supported the system should provide a helpful
message that provides some hope of being able to google a workaround or
whatever.
Sincerely
Peter

the history here is that kvm team added "known models" like conroe,
penryn, etc.
it is just a config change and we can help with the proper format, you
will probably need to re-do it for newer cluster levels.
we moved to the "proper cpu models" (penryn, conroe, etc.) since the
"arbitrary set of cpu flags" was deemed unpredictable wrt robustness of
what a guest OS may expect, and older cpu models weren't prevalent.
