The AMD hw virtualization assist (SVM) is completely different from the Intel facility (VMX), and per= haps there is a bug in bhyve. What is not clear to me, is it a bug to look for in bhyve, or some hw quirk in the reported CPU models. As a first step, could somebody extract the code that is used for broken configuration? I suspect that it is actually ERMS(or FRMS) + AVX2 and not just ERMS memcpy(). --=20 You are receiving this mail because: You are the assignee for the bug.=
