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".

Can you try and change the Cluster CPU type to an AMD type? Y.

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"

Dear Yaniv Kaul, Thanks for your propmt anwer. It seems that your patience did not allow your reading to continue after "CPU_TYPE_INCOMPATIBLE_WITH_CLUSTER". As reported in the last part of my previous mail, the output from vdsClient shows us that the processor is recognised as none of AMD Opteron G1, G2 or G3 (cpuFlags=...) . Thus, Quad-core AMD 2384 cannot match any of Ovirt CPU type options. For confriming, I have just tried, upon reciept of your reply, to add the host to cluster of other CPU types (G1, G2 ..) , to get the same unfortunate result. For your comparaison, here-below shows the "cpuFlags" reported for an AMD Opteron 4284, which Ovirt can treat as either of AMD Opteron G3,G2 and G1 : [root@ovnode02 admin]# vdsClient -s 0 getVdsCaps|grep cpuFlags|grep cpuFlags cpuFlags = fpu,vme,de,pse,tsc,msr,pae,mce,cx8,apic,sep,mtrr,pge,mca,cmov,pat,pse36,clflush,mmx,fxsr,sse,sse2,ht,syscall,nx,mmxext,fxsr_opt,pdpe1gb,rdtscp,lm,constant_tsc,rep_good,nopl,nonstop_tsc,extd_apicid,aperfmperf,pni,pclmulqdq,monitor,ssse3,cx16,sse4_1,sse4_2,popcnt,aes,xsave,avx,lahf_lm,cmp_legacy,svm,extapic,cr8_legacy,abm,sse4a,misalignsse,3dnowprefetch,osvw,ibs,xop,skinit,wdt,lwp,fma4,nodeid_msr,topoext,perfctr_core,arat,cpb,npt,lbrv,svm_lock,nrip_save,tsc_scale,vmcb_clean,flushbyasid,decodeassists,pausefilter,pfthreshold,model_486,model_pentium,model_pentium2,model_pentium3,model_pentiumpro,model_qemu32,model_coreduo,model_qemu64,model_core2duo,model_n270,model_Conroe,model_Penryn,model_Nehalem,model_Westmere,model_Opteron_G1,model_Opteron_G2,model_Opteron_G3 2012/6/14 Hideo GOTO <morpheus.eis@gmail.com>:
