Ticket #19146, comment 2
initial v1 2 2 3 3 CPUID values are ... = guest (host): 4 4 {{{ 5 5 IBRS_IBPB - IA32_SPEC_CTRL.IBRS and IA32_PRED_CMD.IBPB = 0 (1) 6 6 STIBP - Supports IA32_SPEC_CTRL.STIBP = 0 (1) 7 7 SSBD - Supports IA32_SPEC_CTRL.SSBD = 0 (1) 8 8 }}} 9 9 so the NetBSD guest is told the cpu doesn't support IA32_SPEC_CTRL (0x48), 10 10 but still the guest tries to read it: 11 11 {{{ 12 12 00:00:11.518912 IEM: rdmsr(0x48) -> #GP(0) 13 13 00:00:11.518920 Changing the VM state from 'RUNNING' to 'GURU_MEDITATION' 14 14 }}} 15 15 But same values are set in NetBSD 8.1 STABLE amd64 on same host/VirtualBox combo and that one boots and runs just fine.
