Hi All, the flags were -cpu EPYC-Rome-v4,fma4=off,tbm=off,xop=off,fsrm=off,erms=off,pcid=off,misalignsse=off,sse4a=off,cr8legacy=off,xsaves=off,mmxext=off,fxsr-opt=off,osvw=off,sha-ni=off,svm=off,vmx=off,cmov,cx8,fpu,fxsr,syscall,sse,sse2,cx16,lahf-lm,popcnt,sse3,ssse3,sse4.1,sse4.2,avx,avx2,bmi1,bmi2,f16c,fma,abm,movbe,xsave,xsaveopt,adx,aes,fsgsbase,rdrand,rdseed,rdtscp,x2apic,ibpb,stibp,virt-ssbd,amd-ssbd
Unfortunately I had no time to remove the flags one after the other. The replacement is basically -cpu host, with the addition of some flags recommended by the qemu documentation.
