[ovirt-users] Re: Problems with OVirt 4.3 on old IBM HS22 blades

Hi all, I'm pretty new to OVirt so forgive me if this problems is trivial... I received an old IBM BladeCenter H chassis with a few HS22 blades. Some of them are successfully working in my Ovirt farm, but some not. The NonOperational nodes are not used because of missing Westmere model. I use 4.3.10 wersion because 4.4 did not supported some old HW (net adapters, IIRC). The problem is that many blades are almost identical. For example ("Hosts" page --> "General" tab --> "Hardware" section): * BLADE 1 (not working): Manufacturer:IBM Family:System x Product Name:BladeCenter HS22 -[7870H4G]- Version:07 UUID:e36b6686-d111-11df-9dce-e41f13cb90d0 Serial Number:06FP476 CPU Model Name:Intel(R) Xeon(R) CPU X5670 @ 2.93GHz CPU Type:Intel Nehalem IBRS SSBD Family CPU Sockets:2 CPU Cores per Socket:6 CPU Threads per Core:2 (SMT Enabled) * BLADE 2 (working fine): Manufacturer: IBM Family: System x Product Name: BladeCenter HS22 -[7870H4G]- Version: 07 UUID: 30f2fcc8-d0ce-11df-bc12-e41f13cb90cc Serial Number: 06FP469 CPU Model Name: Intel(R) Xeon(R) CPU X5670 @ 2.93GHz CPU Type: Intel Westmere IBRS SSBD Family CPU Sockets: 2 CPU Cores per Socket: 6 CPU Threads per Core: 2 (SMT Enabled) They have same CPU, same HW model, even S/N shows they were produced in the same time. How is it possible to identify X5670 so differently? Any hints/suggestions what to check/change?
