[Qemu-devel] [Bug 921208] Re: win7/x64 installer hangs on startup with 0x0000005d.

[Michael Tokarev]

This prob is still present in current (2.1) qemu, and it is NOT solved
by -cpu kvm64,+nx -- win bluescreens the same way.

Bug description:
  hi,

  during booting win7/x64 installer i'm observing a bsod with 0x0000005d
  ( msdn: unsupported_processor ).

  used command line: qemu-system-x86_64 -m 2048 -hda w7-system.img
  -cdrom win7_x64.iso -boot d

  adding '-machine accel=kvm' instead of default tcg accel helps to
  boot.
