[Qemu-devel] [Bug 1838390] Re: vmx_write_mem: mmu_gva_to_gpa failed when using hvf

[Felipe Franciosi]

Also happens to me on a freshly built Qemu master (tip 23919ddfd561).
MBP15,2 OSX 10.14.6

Qemu command line:
qemu/x86_64-softmmu/qemu-system-x86_64 -cpu host -accel hvf -m 4G -smp 8 -vga 
std -nographic -vnc :1 -netdev user,id=net0 -device e1000e,netdev=net0 
buster.qcow

Guest works fine until I try to build a linux-stable tree with "make
-j8".

  Installed qemu 4.0.0 by homebrew, used below commands:

  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

-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

  Use tcg accelerator has no problem but very slow.
