[ovirt-users] Re: HostedEngine Deployment fails on AMD EPYC 7402P 4.3.7

Hello, This week I tried to deploy Hosted Engine on Ovirt-Node-NG 4.3.7 based Host. At the time the locally deployed Engine ist copied to hosted-storage (in my case NFS) and deployment tries to start the Engine (via ovirt-ha-agent) this fails. QUEMU Log (/var/log/libvirt/qemu/HostedEngine.log) only shows "2019-11-27 16:17:16.833+0000: shutting down, reason=failed". Researching the cause is: The built Libvirt VM XML includes the feature "virt-ssbd" as requirement, which is simly not there. From VM XML:   <cpu mode='custom' match='exact' check='partial'>     <model fallback='allow'>EPYC</model>     <topology sockets='16' cores='4' threads='1'/>     <feature policy='require' name='ibpb'/>     <feature policy='require' name='virt-ssbd'/> from cat /proc/cpuinfo: processor       : 47 vendor_id       : AuthenticAMD cpu family      : 23 model           : 49 model name      : AMD EPYC 7402P 24-Core Processor stepping        : 0 microcode       : 0x830101c cpu MHz         : 2800.000 cache size      : 512 KB physical id     : 0 siblings        : 48 core id         : 30 cpu cores       : 24 apicid          : 61 initial apicid  : 61 fpu             : yes fpu_exception   : yes cpuid level     : 16 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 mmxext fxsr_opt pdpe1gb rdtscp lm constant_tsc art rep_good nopl xtopology nonstop_tsc extd_apicid aperfmperf eagerfpu pni pclmulqdq monitor ssse3 fma cx16 sse4_1 sse4_2 movbe popcnt aes xsave avx f16c rdrand lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs skinit wdt tce topoext perfctr_core perfctr_nb bpext perfctr_l2 cpb cat_l3 cdp_l3 hw_pstate sme retpoline_amd ssbd ibrs ibpb stibp vmmcall fsgsbase bmi1 avx2 smep bmi2 cqm rdt_a rdseed adx smap clflushopt clwb sha_ni xsaveopt xsavec xgetbv1 cqm_llc cqm_occup_llc cqm_mbm_total cqm_mbm_local clzero irperf xsaveerptr arat npt lbrv svm_lock nrip_save tsc_scale vmcb_clean flushbyasid decodeassists pausefilter pfthreshold avic v_vmsave_vmload vgif umip overflow_recov succor smca bogomips        : 5600.12 TLB size        : 3072 4K pages clflush size    : 64 cache_alignment : 64 address sizes   : 43 bits physical, 48 bits virtual power management: ts ttp tm hwpstate cpb eff_freq_ro [13] [14] Any solution/workaround available ?
