+vmx_write_mem: mmu_gva_to_gpa failed when using hvf
+
+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.
+
+Use tcg accelerator has no problem but very slow.
+
+See attachment for full crash report.
+
+
+
+Also happens to me on a freshly built Qemu master (tip 23919ddfd561).
+MBP15,2 OSX 10.14.6

+
+Guest works fine until I try to build a linux-stable tree with "make -j8".
+
+Ubuntu 18.04 VM crashes after login. Works when the RAM is 4 Gb. Posting this here as the error message looked very similar.

+Crash report
+
+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 ...

+
+The QEMU project is currently considering to move its bug tracking to
+another system. For this we need to know which bugs are still valid
+and which could be closed already. Thus we are setting older bugs to
+"Incomplete" now.
+
+If you still think this bug report here is valid, then please switch
+the state back to "New" within the next 60 days, otherwise this report
+will be marked as "Expired". Or please mark it as "Fix Released" if
+the problem has been solved with a newer version of QEMU already.
+
+Thank you and sorry for the inconvenience.

+
+[Expired for QEMU because there has been no activity for 60 days.]
+
+It still happens to me when I try to run Haiku builds on my macos 10.14.
+* QEMU emulator version 7.0.0
+
+Command line:
+qemu-system-x86_64 -machine q35,accel=hvf -cpu host -smp 4 -m 2048 -vga vmware -boot menu=on -drive file="haiku-minimum.mmc",if=none,format=raw,id=x0 -device ide-hd,drive=x0,bus=ide.0 -usb -device qemu-xhci,id=xhci -device usb-mouse -device usb-kbd -serial stdio -rtc clock=vm,base=localtime

+Output:

+
+Haiku boots most of the way and crashes when trying to show desktop. Same happens with -vga virtio and with -vga option completely removed.
