Hi, I have registered a new DELL R730 machine in ovirt 3.5.6 this server type has a Intel(R) Xeon(R) CPU E5-2667 v3 @ 3.20GHz. When i try to add a the new host to a cluster with a haswell architecure i get an error: "Host xxx moved to Non-Operational state as host does not meet the cluster's minimum CPU level. Missing CPU features : model_Haswell" When i look at the hardware tab on the host it says: CPU Model: Intel(R) Xeon(R) CPU E5-2667 v3 @ 3.20GHz and CPU Type: Intel SandyBridge Family This is not a SandyBridge Family processor? When i change the cluster to be a SandyBridge Family cluster the host can be activated. What are my options? - Is it a bug i can get a fix for? (I can't upgrade to 3.6) - Can i force it to report correctly? - What am i loosing in terms of functionality/performance if ovirt thinks its a SandyBridge processor?

Thanks! /Christian _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Ok So i can still benefit from haswell performance?
