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

[Rolando Zappacosta]

Hi Valerio/Clemens,

in my case, Windows 7 alone runs great!

I face this issue after installing PointSec to encrypt the (emulated)
disk from the Windows 7 itself.

Playing with above suggested parameters:

1) "-cpu kvm64,+nx -no-kvm" the BSOD:
        0x0000005D 
(0x0000000078BFBF9,0x0000000000000000,0x0000000000000000,0x0000000000000000)

2) "-cpu kvm64,+nx -enable-kvm" loads, starts and run Windows 7. Now, I install 
PointSec and then the system reboots, installs PointSec boot code and reboots 
again. After that, while PointSec is loading, I get the KVM crash:
        KVM internal error. Suberror: 1

3) Running again "-cpu kvm64,+nx -no-kvm" loads PointSec fine so I type
its configured user/passwd in. It then starts to boot Windows and then I
get again the BSOD

4) From this point on, either the BSOD for "-no-kvm" or the crash for
"-enable-kvm" but NOT before installing PointSec (while, despite of the
BSOD for "-no-kvm", "-enable-kvm" worked just fine). Summing up, I
either get PointSec to load but a Windows' BSOD after it or I get the
KVM crash while PointSec is loading.

The ticket I opened for this under PointSec is #1063807 because, again,
Windows 7 runs fine for me.

Please don't hesitate to ask me for further info,
Rolando.

Title:
  win7/x64 installer hangs on startup with 0x0000005d.

Status in QEMU:
  Confirmed

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.
