[Qemu-devel] [Bug 1723488] Re: HAX on Windows, memory lease error

[Stefan Weil]

See https://software.intel.com/en-us/android/articles/installation-
instructions-for-intel-hardware-accelerated-execution-manager-windows:

"QEMU or Android Emulator will fail to launch if the guest RAM size
(specified with the -m option for QEMU or -memory for Android Emulator)
exceeds 4095MB."

HAX is limited to a 32 bit memory size. There is no way to change that
without breaking compatibility.

Title:
  HAX on Windows, memory lease error

Status in QEMU:
  New

Bug description:
  Today I tried to use QEMU on Windows 8.1 x64 with Intel HAX.

  Command line: qemu-system-x86_64.exe -accel hax -m 8000 -hda
  /opt/disk/ubuntu.img -cdrom /opt/iso/ubuntu-17.04-server-amd64.iso

  Host machine has 32Gb physical memory, I got error:

  HAX is working and emulator runs in fast virt mode.
  **
  
ERROR:A:/msys64/home/admin/git/qemu/target/i386/hax-mem.c:210:hax_process_section:
 assertion failed: (size <= UINT32_MAX)

  When using -m 4000 (and below) everything is fine. But if I try use
  >4000 and <8000 I get crash with errors:

  HAX is working and emulator runs in fast virt mode.
