Hi Mark, Yes I am getting the emails from qemu-devel thanks (seems pretty slow though - the website is faster) I replied to a couple but its over my head mostly now!
I didn't notice Michael had done a v2 patch for 5.1, that's fine with me. I wonder if we can get the debian 5.0 package updated with a patch, or if we have to wait for 5.1 to be packaged with the fix already included from upstream? -- 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=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-kbd -device usb-mouse Perhaps something has changed in Penryn support recently, as that's required for macos?
