I think I was able to fix this crash by specifying the exact host model for the cpu argument.
1. Determine the CPU type of the host machine. $ sysctl -a | grep machdep.cpu.brand_string machdep.cpu.brand_string: Intel(R) Core(TM) i5-4690 CPU @ 3.50GHz 2. Find the matching CPU model supported by QEMU. $ qemu-system-x86_64 -cpu help This CPU corresponds to "x86 Haswell-v4" in this instance. 3. Substitute the CPU model in the QEMU command. $ qemu-system-x86_64 -cpu Haswell-v4 ... -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1838390 Title: vmx_write_mem: mmu_gva_to_gpa failed when using hvf Status in QEMU: New Bug description: Installed qemu 4.0.0 by homebrew, used below commands: 1. qemu-img create -f raw arch-vm.img 100G 2. qemu-system-x86_64 -show-cursor -only-migratable -nodefaults -boot order=d -cdrom archlinux-2019.07.01-x86_64.iso -cpu host -device virtio-keyboard -device virtio-mouse -device virtio-tablet -drive file=arch-vm.img,format=raw,if=virtio -m 4096 -machine q35,accel=hvf,vmport=off -nic user,ipv6=off,model=virtio -smp 4,sockets=1,cores=2,threads=2 -soundhw hda -vga virtio Displayed bootloader menu successfully, select "Boot Arch Linux" then crashed with message: vmx_write_mem: mmu_gva_to_gpa ffff91953b540000 failed.
