[Fedora-xen] Probems installiing windows under xen in FC6

[Robert Thiem]

The xen cdrom config seems to have changed, or at least it's pickier than
I'd like.

Here are the non-comment bits from my config that seems to be working.

import os, re
arch = os.uname()[4]
if re.search('64', arch):
    arch_libdir = 'lib64'
else:
    arch_libdir = 'lib'
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 128
shadow_memory = 8
name = "winxp"
vif = [ 'type=ioemu, bridge=xenbr0' ]
disk = [ 'file:/extra/xen/hvm.img,hda,w',
'file:/extra/xen/hvm-cdrom.iso,hdc:cdrom,r' ]
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
sdl=1
vnc=0
stdvga=0
serial='pty'
