Given that you have already built QEMU from source, what would help enormously is if you can do a "git bisect" between the v5.0.0 tag (working) and your current master (not working) and provide the output of "git bisect log" in this bug report. By identifying the individual commit that broke your test case, it is much easier for developers to understand the issue and propose a fix. ATB, Mark. -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1886318 Title: Qemu after v5.0.0 breaks macos guests Status in QEMU: New Bug description: The Debian Sid 5.0-6 qemu-kvm package can no longer get further than the Clover bootloader whereas 5.0-6 and earlier worked fine. So I built qemu master from github and it has the same problem, whereas git tag v5.0.0 (or 4.2.1) does not, so something between v5.0.0 release and the last few days has caused the problem. Here's my qemu script, pretty standard macOS-Simple-KVM setup on a Xeon host: qemu-system-x86_64 \ -enable-kvm \ -m 4G \ -machine q35,accel=3Dkvm \ -smp 4,sockets=3D1,cores=3D2,threads=3D2 \ -cpu = Penryn,vendor=3DGenuineIntel,kvm=3Don,+sse3,+sse4.2,+aes,+xsave,+avx,+xsa= veopt,+xsavec,+xgetbv1,+avx2,+bmi2,+smep,+bmi1,+fma,+movbe,+invtsc = \ -device = isa-applesmc,osk=3D"ourhardworkbythesewordsguardedpleasedontsteal(c)Apple= ComputerInc" = \ -smbios type=3D2 \ -drive if=3Dpflash,format=3Draw,readonly,file=3D"/tmp/OVMF_CODE.fd" \ -drive if=3Dpflash,format=3Draw,file=3D"/tmp/macos_catalina_VARS.fd" \ -vga qxl \ -device ich9-ahci,id=3Dsata \ -drive id=3DESP,if=3Dnone,format=3Draw,file=3D/tmp/ESP.img \ -device ide-hd,bus=3Dsata.2,drive=3DESP \ -drive id=3DInstallMedia,format=3Draw,if=3Dnone,file=3D/tmp/BaseSyste= m.img \ -device ide-hd,bus=3Dsata.3,drive=3DInstallMedia \ -drive id=3DSystemDisk,if=3Dnone,format=3Draw,file=3D/tmp/macos_catal= ina.img \ -device ide-hd,bus=3Dsata.4,drive=3DSystemDisk \ -usb -device usb-kbd -device usb-mouse Perhaps something has changed in Penryn support recently, as that's required for macos?
