This is a bug. Sorry Laszlo. :) > Not restore MSR_IA32_FEATURE_CONTROL during S3 resume does not affect > at least Linux guest (tested 4.5). Current QEMU may advise the guest > firmware to set bit 20 (for LMCE), bit 2 (for VMX) and bit 0 (lock > bit). > - For LMCE, Linux only checks bit 20 and bit 0 at boot time and then > keeps using the result even after resume. On real hardware, LMCE would not be enabled after resume. I'm not sure what would happen, but it wouldn't be good.
