My setup is very simple qemu-system-x86_64 with args: --machine pc,accel=hvf,usb=off,vmport=off --cpu host --vga std --m 2048 --drive file="$img",format=qcow2,cache=none,detect-zeroes=on --usb -device usb-tablet - -Unfortunately as soon I enable HVF with first 2 lines WinXP SP3 hangs on boot (famous mup.sys). It works fine in TCG. - -I dived into the code checking the differences between HVF, KVM and HAXM and my analysis is: - -1. Sergio Andres Gomez Del Real b7394c8394 - replaces explicit VMCS_GUEST_INTERRUPTIBILITY checks with hflags/hflags2. - -2. Paolo Bonzini 92d5f1a414 - changes hflags/hflags2 behavior which breaks in the end HVF interrupt handling and makes WinXP unable to boot. NOTE: This does not break I believe KVM and HAXM as they still do explicit check instead what HVF does in 1. That's why it was probably not reported and Qemu macOS users are rather niche ;) - -Reverting 92d5f1a414 makes WinXP boot well and work flawlessly. -Unfortunately b7394c8394 is not easy anymore as too many changes on the way, so it may be not an option. - -This can be reproduced simply by installing /Users/ono/VM/ISO/en_windows_xp_professional_with_service_pack_3_x86_cd_vl_x14-73974.iso -with HAL as "Standard PC" selectable with F5 on first run. - -I can also provide fresh ~600MB qcow2 image (without activation key entered yet) that is created before boot that fails. No need for full XP installation to test that. - -Nevertheless I would really appreciate Paolo looking into this. -Many thanks for great software, -Adam \ No newline at end of file |
