Thanks Michael,
I usually use libvirt, but this qemu script has the same problem:
qemu-system-x86_64 \
-enable-kvm \
-m 4G \
-machine q35,accel=kvm \
-smp 4,sockets=1,cores=2,threads=2 \
-cpu
Penryn,vendor=GenuineIntel,kvm=on,+sse3,+sse4.2,+aes,+xsave,+avx,+xsaveopt,+xsavec,+xgetbv1,+avx2,+bmi2,+smep,+bmi1,+fma,+movbe,+invtsc
\
-device
isa-applesmc,osk="ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"
\
-smbios type=2 \
-drive if=pflash,format=raw,readonly,file="/tmp/OVMF_CODE.fd" \
-drive if=pflash,format=raw,file="/tmp/macos_catalina_VARS.fd" \
-vga qxl \
-device ich9-ahci,id=sata \
-drive id=ESP,if=none,format=raw,file=/tmp/ESP.img \
-device ide-hd,bus=sata.2,drive=ESP \
-drive id=InstallMedia,format=raw,if=none,file=/tmp/BaseSystem.img \
-device ide-hd,bus=sata.3,drive=InstallMedia \
-drive id=SystemDisk,if=none,format=raw,file=/tmp/macos_catalina.img \
-device ide-hd,bus=sata.4,drive=SystemDisk \
-usb -device usb-host,hostbus=1,hostaddr=3
my modprobe script is below, i haven't changed anything:
options kvm ignore_msrs=1 report_ignored_msrs=0
options kvm-intel nested=y ept=y enable_apicv=1
options vfio-pci ids=10de:128b,10de:0e0f
softdep nouveau pre: vfio-pci
softdep snd_hda_intel pre: vfio-pci
kernel 5.6 and 5.7 broke VFIO in macos guests, but now qemu itself has
broken the guest even without vfio (and even in 5.5 kernel).
Regards.
