Hi,

I’ve an strange issue in one of my hosts, it’s missing a lot of CPU flags that oVirt seems to require:

[root@c4140 ~]# vdsm-client Host getCapabilities | egrep "cpuFlags|cpuModel"
    "cpuFlags": "ssse3,mca,ept,pdpe1gb,vmx,clwb,smep,msr,acpi,pge,sse4_2,nopl,cqm_mbm_total,cx16,avx512vl,aperfmperf,xsaves,3dnowprefetch,nonstop_tsc,cmov,mce,intel_pt,avx512f,fpu,pku,tsc,sdbg,erms,pse36,md_clear,apic,sse,pcid,clflushopt,xtopology,pts,monitor,vpid,cpuid,hle,mba,ss,cqm,avx2,ibpb,xgetbv1,flush_l1d,mmx,epb,pti,fxsr,dca,nx,syscall,stibp,mtrr,cx8,sse2,avx,sep,intel_ppin,lm,tm,bts,adx,bmi1,smx,popcnt,pclmulqdq,lahf_lm,mpx,rdseed,cqm_llc,avx512cd,cdp_l3,f16c,invpcid,fsgsbase,cpuid_fault,tm2,smap,dts,pse,xsave,sse4_1,constant_tsc,pat,tsc_deadline_timer,vnmi,avx512dq,dtes64,xsaveopt,ida,pdcm,tpr_shadow,pln,de,x2apic,avx512bw,pae,rdrand,clflush,rdtscp,art,cqm_mbm_local,pebs,ssbd,movbe,pbe,tsc_adjust,vme,ht,est,bmi2,cat_l3,dtherm,ospke,rdt_a,aes,ibrs,rep_good,fma,xtpr,ds_cpl,abm,xsavec,invpcid_single,flexpriority,cqm_occup_llc,pni,rtm,arat,arch_perfmon",
    "cpuModel": "Intel(R) Xeon(R) Gold 6130 CPU @ 2.10GHz",

In a properly working host it have flags like those ones:

model_Westmere-IBRS,model_kvm32,model_core2duo,model_Opteron_G1,model_Broadwell,model_qemu64,model_Broadwell-noTSX,model_Nehalem-IBRS,model_Haswell-IBRS,model_pentium2,model_Broadwell-IBRS,model_Haswell-noTSX,model_Haswell,model_Haswell-noTSX-IBRS,model_Conroe,model_pentium,model_n270,model_Nehalem,model_IvyBridge-IBRS,model_kvm64,model_SandyBridge,model_pentium3,model_Broadwell-noTSX-IBRS,model_qemu32,model_486,model_IvyBridge,model_SandyBridge-IBRS,model_Westmere,model_Penryn,model_Opteron_G2,model_coreduo",

But in this machine it’s totally missing. I know this model_ flags are an oVirt thing, since they aren’t default on the CPUs.

The host machine is a Dell C4140 compute node, the firmware is fully updated, so I’ve done the basic to figure out what’s happening.

Thanks,
