KVM-29 + Windows Server 2003 = kernel panic

Hello list,

I am trying to install Windows Server 2003 using KVM-29, but getting
kernel panics every time.

Some notes:

* CPU model: 2 x Dual-Core AMD Opteron Processor 2210
* KVM versions: KVM-29
* Host: RHEL5 x86_64, kernel 2.6.18-8.1.8.el5
* Guest: Windows Server 2003 Standard edition
* the problem does NOT appear with the "-no-kvm" switch
* the server doesn't have a X server, so I had to work through VNC

---

Steps I followed:

1) created a brand new VM disk image
# sudo -u kvm qemu-img create -f qcow VM.img

2) set up a bridge on the host using RedHat's own scripts (called sw0)

3) manually set up a TAP device
# tunctl -u kvm
# brctl addif sw0 tap0

4) started the installation with the following command line
# sudo -u kvm qemu-system-x86_64 -hda VM.img -cdrom Win2003.iso
-boot d -net nic,model=rtl8139 -net tap,ifname=tap0,fd=h,script=no -m
1024 -no-acpi -daemonize -usb -usbdevice tablet -vnc :1

5) pressed F5 and selected "Standard PC"

6) waited for setup to format the disk and copy the files and auto-reboot

---

The 1st part of the installation goes smoothly. However, as soon as the
VM is rebooted and Windows tries to start the 2nd part, KVM crashes and
leads to a kernel panic.

Here are some explanatory pics:

Please let me know if there is anything I can do to help you.

Thanks,

AS
