W2k3 Installation fails with segfault.

W2k3 Installation fails with segfault.

[Fabian Deutsch]

Hey,

I just tried the latest kvm head (kernel+userspace). But my fresh W2k3 Installation failed with a segfault.
Facts:

CPU:
model name      : Intel(R) Xeon(R) CPU           X3210  @ 2.13GHz
MemTotal:      8196292 kB

Host:
Fedora release 8 (Werewolf) (up to date)
Linux fry.localdomain 2.6.24.3-34.fc8 #1 SMP Wed Mar 12 16:51:49 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux

KVM:
kernel: kvm-63-791-g361be34
userspace: kvm-63-105-g92b1c7d

Guest:
Windows Server 2003 Standard

Qemu:
/usr/bin/qemu-system-x86_64 -M pc -m 1024 -smp 2 -monitor pty -no-acpi -boot c -hda /root/win_smp.img -cdrom /root/win-all-in-one.iso -net nic,macaddr=52:54:00:d8:65:c9,vlan=0 -net tap,fd=12,script=,vlan=0 -usb -vnc 127.0.0.1:0 
char device redirected to /dev/pts/2

Bug:
During installation (17min left) the (later) following segfault appears.
Maybe something like http://sourceforge.net/tracker/index.php?func=detail&aid=1890597&group_id=180599&atid=893831.
