Windows 64 bits install BSOD : UNSUPPORTED_PROCESSOR (only without kvm)

[Rafaël Carré]

Windows DVD starts loading and then stops with error 0x5d
MSDN tells us that 0x5d means unsupported_processor

The guest CPU is 64 bits though, the DVD fails early if booted on a 32bits CPU

Tested versions: 0.14.1, git (932eacc158)

qemu-system-x86_64 -m 1024 -boot d -cdrom win7.iso -hda win7.hdd

Tried various -cpu options: Nehalem, core2duo, Penryn, Conroe, Opteron_G3

x86_64 host, without vx-t

Same iso is reported to install fine with kvm

I hit this bug too. Definitely a show-stopper. Going to have to put VirtualBox on it in the meantime.
