[ovirt-users] which cpu type should I chose ??

Hi: 1.My server using as ovirt host is built on virtualbox and the cpu info is: vendor_id : GenuineIntel cpu family : 6 model : 142 model name : Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz stepping : 10 cpu MHz : 1992.002 cache size : 8192 KB physical id : 0 siblings : 3 core id : 2 cpu cores : 3 apicid : 2 initial apicid : 2 fpu : yes fpu_exception : yes cpuid level : 22 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 nx rdtscp lm constant_tsc rep_good nopl xtopology nonstop_tsc cpuid tsc_known_freq pni pclmulqdq vmx ssse3 cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt aes xsave avx rdrand hypervisor lahf_lm abm 3dnowprefetch invpcid_single pti tpr_shadow flexpriority fsgsbase avx2 invpcid rdseed clflushopt md_clear flush_l1d bugs : cpu_meltdown spectre_v1 spectre_v2 spec_store_bypass l1tf mds swapgs itlb_multihit srbds bogomips : 3984.00 clflush size : 64 cache_alignment : 64 address sizes : 39 bits physical, 48 bits virtual power management: 2.On the ovirt host page it appears that the host is unusable.The log info is: Host ohost3 moved to Non-Operational state as host does not meet the cluster's minimum CPU level. Missing CPU features : model_IvyBridge, ssbd, spec_ctrl 3.I think the problem is on cluster's cpu type setting, but which one should I chose to fit for the host?
