winxp.64 fails to install in -rc2 with kvm

Guest commandline:
sudo ./x86_64-softmmu/qemu-system-x86_64 -L pc-bios -name 'vm1' -monitor stdio -drive file=~/work/images/winXP-64.qcow2,if=ide,cache=writeback -net nic,vlan=0,model=rtl8139,macaddr=52:54:00:12:34:56 -net user,vlan=0 -m 512 -cdrom ~/work/isos/en_windows_xp_professional_x64.iso -enable-kvm -redir tcp:5000::22

Steps to reproduce:

1. git checkout -b 12rc2 v0.12.0-rc2
2. ./configure --target-list=x86_64-softmmu
3. make
4. qemu-img create -f qcow2 ~/work/images/winXP-64.qcow2 20G

Guest boots XP.64 installer, loads some files and then hangs at "Starting Windows XP"

Reverting to -rc1 and XP installs just fine. Git bisect points to:

commit 066263f37701687c64af9d8825e3376d069ebfd4
Author: Andre Przywara <email address hidden>
Date: Mon Dec 7 11:58:02 2009 +0100

cpuid: Fix multicore setup on Intel

Reverting this fixes the problem.

Different kvm modules seem to affect this install as well. Switching
to different kvm-kmod packages:

2.6.32 modules work fine with 0.12.0-rc2, no issues at all

2.6.30 modules fail, reverting the above commit doesn't help, seems to
be in the same boat as 2.6.28 modules

2.6.31.5 (roughly equivalent to Fedora11 modules) work on -rc1, fail on
rc2, reverting above commit fixes -rc2.

Ryan,
can you still reproduce this with the stable versions (0.12.4)?

[Ryan Harper (raharper)]

Yeah, I can still reproduce with 0.12.4 on a fedora11 host. Also broken with qemu.git HEAD as of today as well. On the f11 host kvm modules, reverting the referenced commit doesn't help.

[Thomas Huth (th-huth)]

Fedora 11, QEMU 0.12 and Windows XP are pretty much outdated nowadays, so I guess nobody will take care of this ticket anymore - sorry! So I'm closing this as "Won't fix" now. (Anyway, if you still can reproduce this problem with the latest version of QEMU, feel free to open the bug again)
