           Summary: unable to install windowsXP - qemu-crash if vif use
                    ioemu and windows xp crash by installing if vif= ['']
           Product: Xen
           Version: unstable
          Platform: x86-64
        OS/Version: other
            Status: NEW
          Severity: blocker
          Priority: P2
         Component: HVM
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: Andreas.Matthus@xxxxxxxxxxxxx


I have a new maschine with dual opteron-dual-core (2216), 4 GB RAM. 
dom0 run with 4 CPU and 256 MB RAM using a debian etch.   
domU run i. e. with another debian - that ist O.K.

If I wont to install windowsXP (32 bit) for a domU like your text
(xen_install_windows.pdf - with using new entry for cdrom) qemu-dm crash.

If I vary the vif-statement to
vif=[''] 
the installation starts. After loading the drivers some seconds I got a dark
window in qemu and then a blue-screen "Stop ..." 
I'm not shure, what error number it was (STOP: 0x0000007B ?- that is
INACCESSIBLE_BOOT_DEVICE). I probed twice: a file and later a real partition.
Here my configuration:
------------------
import os, re
arch = os.uname()[4]
if re.search('64', arch):
    arch_libdir = 'lib64'
else:
    arch_libdir = 'lib'
kernel = "/usr/lib/xen-ioemu-3.0-unstable/boot/hvmloader"
builder='hvm'
memory = 512
name = "wxp001"
vif = [ '' ]
# or vif = [ 'type=ioemu, bridge=xenbr1' ]
# yes I use xenbr1
disk = [ 'phy:/dev/sda5,ioemu:hda,w' ]
# or disk = [ 'file:/mnt/sda10/wxp-001.qcow,ioemu:hda,w' ]
device_model = '/usr/' + arch_libdir + '/xen-ioemu-3.0-unstable/bin/qemu-dm'
disk=[ 'file:/mnt/sda10/winXP_mit_SP2.iso,hdc:cdrom,r' ]
# also tested disk=[ 'file:/mnt/sda10/winXP_mit_SP2.iso,ioemu:hdc:cdrom,r' ]
boot='d'
sdl=1
vnc=0
vncviewer=0
ne2000=0
-----------------
The crash of qemu-dm is surely a bug 
- the crash of windows can be my mistake in the configuration. I created the
diskimage-file with 
qemu-img create -f qcow wxp-001.qcow 5GB 
normal qemu works with this file fine.
