libvirt users - May 2012 - win-xp guest after reboot: could not open disk image /dev/sr0: mo medium found and extreme sluggisch

Hi, 

win-xp won't boot after installation. The CD is needed to boot from. How can
I
convince win-xp to boot?


That's what I did: 
=================I installed win-xp guest on debian squeeze: 

# virt-install --connect qemu:///system --name winxp-prof --ram 1024 \
--disk path=/dev/vg-levo/winxp-kvm,size=10 \
--network bridge:br0 --vnc --os-variant winxp --cdrom /dev/sr0

/dev/vg-levo/winxp-kvm  is a lvm (logical volume, 10GB)

Installation worked, but was extrem slow. Machine: Lenovo B560, core i3, 6 GB
RAM.

WinXP made a normal reboot after installation, I ejected install cd, then: 

virt-manager output:
Error starting domain: internal error Process exited while reading console log
output:
chard device redirected to /dev/pts/2
qemu: could not open disk image /dev/sr0: mo medium found

So I inserted the CD and a black blanc screen appeared. Windows didn't boot.

I deleted installation configuration: # virsh undefine winxp-prof
I invoked virt-install (see above) once again ... and win-xp is booting ... what
a surprise, without installing again after undefine .. ! The reason: the lvm
partition
was not deleted. 

WinXP now always needs a CD to boot and is extreme sluggisch. Right mouse click
lasts about
one minute!

I found it myself:

it's because in xml-file was /dev/sr0 . kvm checked the presence of sr0 
If sr0 is not present the boot process makes stop. 

Solution:  change /dev/sr0 to /media/cdrom0  (in debian squeeze always existing)
    in xml-file or delete the disk section entirely:

   <disk type='block' device='cdrom'>
      <driver name='qemu' type='raw'/>
      <source dev='/media/cdrom0'/>       <<<==== changed
      <target dev='hdc' bus='ide'/>
      <readonly/>
      <address type='drive' controller='0' bus='1'
unit='0'/>
    </disk>

BTW: unfortunately the cdrom is not passed throught. I'll find it out some
day ..

Only WinXP-Prof is very slow. WinXP home is quite fast. I found

to speed up WinXP , Tomorrow I've time to read it ...
