[ovirt-users] Older hardware deployment

[Chas Ecomm]

It gives the “Host CPU type is not compatible with Cluster Properties” message, and it doesn’t matter what CPU compatibility level I set it to (I’ve tried all of them) it gives the same error.  I’ve seen a few others with this kind of issue but not a solid description of how to modify the database to include processor families prior to Conroe.

What errors are you getting?

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!!
