attached the trace.dat (tar-gzipped) as recommended. Hope this helps finding the issue. The file should capture the following:
- windows 8 with screen that shows that the last boot attempts failed
- issued system_reset on qemu commandline
- startup of windows 8 that stalls
** Attachment added: "trace.tgz"

Title:
Core2Duo and KVM may not boot Win8 properly on 3.x kernels
Status in QEMU:
New
Bug description:
When I start up QEMU w/ KVM 1.7.0 on a Core2Duo machine running a vanilla kernel 3.4.67 or 3.10.12 to run a Windows 8.0 guest, the guest freezes at Windows 8 boot without any error.
When I dump the CPU registers via "info registers", nothing changes, that means the system really stalled. Same happens with QEMU 2.0.0 and QEMU 2.1.0.
It stalls when the Windows logo is displayed and the balled circle starts rotating.
But - when I run the very same guest using Kernel 2.6.32.12 and QEMU
1.7.0 or 2.0.0 on the host side it works on the Core2Duo. Also the
system above but just with an i3 or i5 CPU it works fine.
I already disabled networking and USB for the guest and changed the graphics
card - no effect. I assume that some mean bits and bytes have to be set up
properly to get the thing running.
Seems to be related to a kvm/processor incompatibility.
Windows XP runs on all combinations without any issues. Windows 8.1
guests have the same issues as Windows 8.0.
An example command line that does not boot Windows 8 is:
qemu-system-x86_64 -machine pc-i440fx-1.5,accel=kvm,kernel_irqchip=off -daemonize -cpu kvm32,+sep,+nx -nodefaults -vga std -readconfig /usr/X11R6/X11etc/ich9-ehci-uhci.cfg -device usb-host,bus=ehci.0,hostport=1.2 -device usb-tablet -drive file=/dev/sdb,cache=writethrough,if=none,id=x -device ide-drive,drive=x -m 1024 -monitor telnet:127.0.0.1:5100,nowait,server -vnc :1 -L /usr/X11R6/share/qemu -boot c -localtime -enable-kvm -no-shutdown
enabling the kernel_irqchip, removing the sep, disabling usb, changing
the machine type or changing the monitor type (SDL or VNC) has no
effect.
