[Users] Ovirt does'nt recognize "Quad-core AMD Opteron" as Opteron

Dear sirs, We added a HP DL365-G5 server with 2 x "Quad-core AMD Opteron 2384" to a working ovirt-node cluster ( CPU type of the cluster = "AMD Opteron G3". Existing node servers use AMD Opteron 4284) . Then, the Ovirt-engine refuses to intergrate DL365-G5, reporting an error of the type: "CPU_TYPE_INCOMPATIBLE_WITH_CLUSTER". Ovirt (RHEV) does'nt support AMD Opteron 2xxx series , though they are KVM compatible? (This HP DL365 worked fine with VMWare). Any solution, advise, comment is wellcome, since we do not much want to revirt to VMWare. FIY, On the ovirt-engine's node information, "CPU Name" is reported as [N/A] and "CPU Type" as "Quad-Core AMD" Here below is the content of the /proc/cpuinfo on the HP DL365-G5: --------------------------------------------------------------------------------- processor : 7 vendor_id : AuthenticAMD cpu family : 16 model : 4 model name : Quad-Core AMD Opteron(tm) Processor 2384 stepping : 2 microcode : 0x1000086 cpu MHz : 2700.096 cache size : 512 KB physical id : 1 siblings : 4 core id : 3 cpu cores : 4 apicid : 7 initial apicid : 7 fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall mmxext fxsr_opt pdpe1gb rdtscp lm 3dnowext 3dnow constant_tsc rep_good nopl nonstop_tsc extd_apicid pni monitor cx16 popcnt lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs skinit wdt npt lbrv svm_lock nrip_save bogomips : 5400.44 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 48 bits physical, 48 bits virtual power management: ts ttp tm stc 100mhzsteps hwpstate --------------------------------------------------------------------------------------- According to vdsClient's info as shown below, Quad-core Opteron is recognized as if it were a good old 32 bit CPU.
