    initial v1  
    22 
    33CPUID values are ... = guest (host): 
    4  
     4{{{ 
    55IBRS_IBPB - IA32_SPEC_CTRL.IBRS and IA32_PRED_CMD.IBPB  = 0 (1) 
    66STIBP - Supports IA32_SPEC_CTRL.STIBP                   = 0 (1) 
    77SSBD - Supports IA32_SPEC_CTRL.SSBD                     = 0 (1) 
    8  
     8}}} 
    99so the NetBSD guest is told the cpu doesn't support IA32_SPEC_CTRL (0x48), 
    1010but still the guest tries to read it: 
    11  
     11{{{ 
    121200:00:11.518912 IEM: rdmsr(0x48) -> #GP(0) 
    131300:00:11.518920 Changing the VM state from 'RUNNING' to 'GURU_MEDITATION' 
    14  
     14}}} 
    1515But same values are set in NetBSD 8.1 STABLE amd64 on same host/VirtualBox combo and that one boots and runs just fine.
