Comment 1 for bug 1821595

Hi,

Having a similar issue here, running "QEMU emulator version 4.2.91 (v5.0.0-rc1-31-g146aa0f104-dirty)"

Configuration / build command line,
./configure --cross-prefix=x86_64-w64-mingw32- --target-list=x86_64-softmmu --enable-whpx --enable-fdt --enable-gtk --enable-vnc --disable-pie --enable-opengl && make -j16 && make -j16 installer

And the QEMU command line,
qemu-system-x86_64.exe \
    -m 2G \
    -machine q35 \
    -cpu Penryn \
    -accel whpx \
    -device isa-applesmc,osk="ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc" \
    -smbios type=2 \
    -drive if=pflash,format=raw,readonly,file="./firmware/OVMF_CODE.fd"\
    -drive if=pflash,format=raw,file="./firmware/OVMF_VARS-1024x768.fd" \
    -usb -device usb-kbd -device usb-mouse \
    -netdev user,id=net0 \
    -device e1000-82545em,netdev=net0,id=net0,mac=52:54:00:c9:18:27 \
    -device ich9-ahci,id=sata \
    -drive id=ESP,if=none,format=qcow2,file=ESP.qcow2 \
    -device ide-hd,bus=sata.2,drive=ESP \
    -drive id=InstallMedia,format=raw,if=none,file=BaseSystem.img \
    -device ide-hd,bus=sata.3,drive=InstallMedia \
    -drive id=SystemDisk,if=none,file=MyDisk.qcow2 \
    -device ide-hd,bus=sata.4,drive=SystemDisk \

If I remove (only), -accel whpx \ => Then it all runs, just very slowly ;-).

Any suggestions, things to try?

Thanks!
