How to install WinXp from CD using KVM

[jambalaya]

Hi.
To begin with, I looked through a lot of material in this forum and google, but I sort of can't find anything to guide me (or I can't deal with the information I found properly, which is very possible).
I have a running 64-bit Kubuntu 8.04 installation, and I have kvm installed, along with qemu. I also have a windows xp CD in the drive, I am able to load the kvm and kvm-intel module (I have a Core 2 Duo). I created an image file:
"qemu-img create -f qcow xpsp2.img 3G" in my home directory, and I'm stuck now - I don't know what to do because all the windows xp howtos seemed to be working with *.iso images, and I have an ordinary cd. Could anyone help me find some information on how to install that correctly?
Also, the guest OS is 32-bit, will this work properly on a 64-bit host?
Thanks.

Hi.
I managed to install it at last, the line to boot from cd is (in case anyone reads that later):
sudo qemu-system-x86_64 -hda xpsp2.img -boot d -cdrom /dev/cdrom -m 512 -localtime

However, now when I start qemu, the console says:
Could not open '/dev/kqemu' - QEMU acceleration layer not activated: No such device or address

It works without it, but I read this could speed things up dramatically. I installed kqemu-common, but I don't know if this is enough. Does anyone know how to deal with this?
Thanks.

1. make sure you add your id to group 'kvm'
(or you if you want to do it quick, run as root for now)

2. An easy command would be:
kvm -m 512 -cdrom /dev/cdrom -hda <path to your image file>/xpsp2.img -boot d


Or just type kvm, and it'll give you a list of options.

Thank you, I didn't know I had to run it with the kvm command.
Now I don't get any error message, and the guest os boots and runs quicker, it really makes the difference.
Thanks!

How to write the configure XML file? My XML is :
...
<os>
<type arch='i686' machine='pc-0.11'>hvm</type>
<boot dev='cdrom'/>
<boot dev='hd'/>
<bootmenu enable='yes'/>
</os>
...
But error occurs:
Error launching details: Domain not found: no domain with matching uuid '3e53142a-7243-0a12-2b8a-3946653516a0'
When I change it:
...
<os>
<type arch='i686' machine='pc-0.11'>hvm</type>
<boot dev='hd'/>
</os>
...
It works!

Hi link0315,

A while back I wrote an article on using XML for libvirt guest creation, which will help you understand how the XML is defined.

http://blog.allanglesit.com/2011/03/kvm-guests-manipulating-libvirt-xml-for-guest-creation/

That said the easiest way is to take an existing XML and modify it, the original can come from another VM:
# virsh dumpxml vm1 > vm2.xml
And then be edited with vi to suit the new VMs needs before defining it. Or you could use Virt-Manager to define the VM (which will create the XML) and then edit the VM configuration:
# virsh edit vm2
