Not possible to boot installer of NetBSD 9.0RC1. cc me as I am not
subscribed to list.
CPUID values are ... = guest (host):
IBRS_IBPB - IA32_SPEC_CTRL.IBRS and IA32_PRED_CMD.IBPB = 0 (1)
STIBP - Supports IA32_SPEC_CTRL.STIBP = 0 (1)
SSBD - Supports IA32_SPEC_CTRL.SSBD = 0 (1)
so the NetBSD guest is told the cpu doesn't support IA32_SPEC_CTRL
(0x48),
but still the guest tries to read it:
NetBSD 8.1 STABLE amd64 on same configuration with same values boots
just fine and works.
