I've searched on this issue all over the place and not found a full answer.

I've got a lab with older Dell PE860 servers with Pentium D processors.  We
are attempting to prove out that we can move from VMware to KVM and oVirt,
but with 3.5 we can't get these servers to enter into a cluster due to the
age of the processors.

I've seen it referenced in a few list entries to modify 'the database' to
put CPUInfo entries in for the processor capabilities of this processor, but
it is unclear to me and I've been unable to find any documentation that
speaks to what database and how to modify it safely.

I know we could update these servers and get better power consumption, heat
generation, etc., but it's not in the cards and I can't move my newer
servers until we prove it out with these older ones, which ran ESXi 5.5 with
absolutely no issue.  This cluster will be a functional test and small tools
cluster ultimately, so I don't really care about their lower end specs,
either.

Would installing something older than 3.5 help me here?  Or is there some
doc somewhere I've just not found that describes this process of updating
the DB with these CPU parameters.

TIA!!
