Comment 7 for bug 921208

Hi,
I almost identical problem so i post here my comment.
I'm trying to use qemu 1.1.0 to run some vm on a RHEL5.8 _without_ kvm accelaration
(the host have 24 cpu core, I can't install kvm module on the server, policy problem,
but I still want to exploit some cpu power).

I compiled qemu 1.1.0 with default options (just --prefix=...) and it works with linux
guests (very few try, ttylinux, Oracle Linux, all seems fine.) but I'm not able to start
any Microsoft Windows guest (tried installed guest from virtualbox and iso installation cd).
Here the systems I tried:

Windows 2008 R2 x64:
qemu-system-x86_64 -m 2048 -cdrom win2008r2x64.iso -hda test.win2008.qcow2
blue screen:

Windows 8 ConsumerPreview 32bit:
qemu-system-i386 -m 2048 -cdrom Windows8-ConsumerPreview-32bit-English.iso -hda test.win8-32.qcow2

Windows XP SP3 32bit:
qemu-system-i386 -m 512 -cdrom /work.local/software/WindowsXP-SP3/Win_XP_Pro_SP3.iso -hda /work.local/vm/test.winXP.qcow2
Hang on a black screen

the host have 2.6.18-308.el5 kernel and cpus are:

I tried the same ISOs on a netboot with kernel vanilla 3.4.2 and core 2 duo cpu:
with kvm (-enable-kvm):
Windows 2008 R2 x64: boot ok
Windows 8 ConsumerPreview 64bit: boot ok
Windows 8 ConsumerPreview 32bit: boot ok
Windows XP SP3 32bit: hangs with black screen as in bug #1013888
(https://bugs.launchpad.net/qemu/+bug/1013888)

without kvm: all fails
