Here's the simplest case that I can reproduce with:
/usr/local/bin/qemu-system-x86_64 \
-S \
-machine pc,accel=kvm \
-cpu host \
-m 4096 \
-smp 2,sockets=1,cores=2,threads=1 \
-vga std \
-vnc :0 \
-no-user-config \
-nodefaults \
-monitor stdio \
-serial none \
-parallel none \
-net none \
-cdrom en_windows_10_consumer_edition_version_1809_updated_april_2019_x64_dvd_b6a14039.iso
This blue screens with a stop code: MICROCODE REVISION MISMATCH
If I disable SMP for the guest or add the ucode-rev option it boots to
the installer. I don't currently have newer local ISO images, but I
could download some if necessary. Host cpu:
