Thanks in advance for any help you can provide

We are testing Ovirt 3.2.2 on a 2007 vintage dual Xeon 5060 (Dempsey) Supermicro Superserver. http://en.wikipedia.org/wiki/Xeon#5000-series_.22Dempsey.22. This hardware runs Centos 6.5 and KVM / virt manager just fine, and we have be running many virtual machines on this hardware with reasonable performance for many years

We are getting the message: "Non-Operational state as host does not meet the cluster's minimum CPU level" each time we create a host.

After researching this list, we are coming to the conclusion that this older processor is not being recognized by ovirt.

Output of virsh -r capabilities and vdsClient -s 0 getVdsCaps are posted below.

We havent found anyone with exactly this use case in our research. The closest thread is this:

http://lists.ovirt.org/pipermail/users/2012-May/007536.html

This poster was able to add some lines to the db to recognize his processor. Here is the advice he received in that post.

We think we understand what is happening: our processors capabilities will be matched by processor type line 2 or 3, and then the host won't be rendered "non-operational".

My Questions:

1. is this the correct change to ServerCPUList config in the db,

2. Is this the proper way to get support for older processors?

3. Is this documented anywhere? Can someone please help with a step by step for less experienced users?

4. Wouldn't it be reasonable to expect Ovirt to support processors that KVM supports by default? What is the minimum perceived processor expected to be? why is is conroe, when perfectly functional processors a few months older cause errors?

The server hardware we are using is fine for our purposes, we don't intend to upgrade for this purpose.at this time.

Thanks again

Peter
