Ok So i can still benefit from haswell performance? /Christian 2015-12-18 14:51 GMT+01:00 Simone Tiraboschi : > > > On Fri, Dec 18, 2015 at 1:02 PM, gflwqs gflwqs wrote: > >> 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.

[ovirt-users] ovirt reports an Intel(R) Xeon(R) CPU E5-2667 v3 @ 3.20GHz as a Intel SandyBridge Family?
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?
