RE: [Xen-users] WinXP CD-ROM problems

["Tait Clarridge" <Tait.Clarridge@xxxxxxxxxxxx>]

Ok, Have you tried shutting down the VM completely (not just a reboot)
and bringing it back up again?
Have you upgraded any part of your host recently? Or of your Xen
installation?

Best,
Tait

Just with dd if=/dev/cdrom of=image.iso  Its been about a year since I
did it and that's how I installed Windows.  Of course today also WinXP
thinks it needs the disk for something stupid.

Here's my hvm file  (with the old disk line)
-------------------------------
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=512

shadow_memory = 8

name = "WinXP-001"

vif = [ 'type=ioemu, bridge=xenbr0' ]

disk = [ 'phy:/dev/VG_Guests/WinXP-001,ioemu:hda,w',
'file:/opt/xen_stuff/winxp.iso,hdc:cdrom,w',
'phy:/dev/scd0,hdd:cdrom,r' ]

device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'

boot="cd"

sdl=0

vnc=1

vnclisten="127.0.0.1"

vncdisplay=21

vncpasswd=''

stdvga=0

serial='pty'

usb=1
