using kvm on opensuse 11.1 is easy.
http://www.linux-kvm.org/page/HOWTO
my hardware: hp elitebook 6930p
install opensuse 11.1boot cd with acpi=off
don't use auto configuration during the install process
i disable auto login too and did an internet update and it is so slow... mainly i guess due to my bb connection.. it keep breaking..
so u can skip internet update
to
install KVM follow this:

I installed windows 2008 server using a 10gb image file.
create image fileqemu-img create -f qcow2 disk.img 10G
How do I use dd command to create an ISO image?
Put CD into CDROM
Do not mount CD. Verify if cd is mounted or not with mount command:
# mount
If cd was mouted automatically unmout it with umount command:
# umount /dev/cdrom
OR
# umount /mnt/cdrom
Create CD-ROM ISO image with dd command:
# dd if=/dev/cdrom of=/tmp/cdimg1.iso
Where,
- if=/dev/cdrom: Read from /dev/cdrom (raw format)
- of=/tmp/cdimg1.iso: write to FILE cdimg1.iso i.e. create an ISO image
src: http://www.cyberciti.biz/tips/linux-creating-cd-rom-iso-image.html
boot the guest from a iso fileqemu-kvm -m 256 -hda disk.img -cdrom winxpsp2.iso -boot d
-boot d instruct qemu to boot from cdrom
what nic are supported?qemu-kvm -hda vista1.img -net nic,model=?,macaddr=00:16:3e:23:38:45 -net user -cdrom BootMedia.iso -boot d &
opensuse:/kvm-disk # qemu: Supported ISA NICs: ne2k_isa
qemu: Supported PCI NICs: i82551 i82557b i82559er ne2k_pci pcnet rtl8139 e1000 virtio
i82557b is supported by my vista
Insert KVM Modules
Insert the kvm modules as follows (as root)
For Intel processors
opensuse11:~ # modprobe kvm
opensuse11:~ # modprobe kvm-intel
For AMD processors
opensuse11:~ # modprobe kvm
opensuse11:~ # modprobe kvm-amd
To confirm the modules OK,
opensuse11:~ # lsmod | grep kvm
kvm_intel 67824 0
kvm 182936 1 kvm_intel
However, this setting lost on a reboot.
To insert this module at boot time, Click Computer – YaST – System – “/etc/sysconfig editor”. This launches the sysconfig editor.
Click “+” next to “system” and then “+” next to Kernel. Click “MODULES_LOADED_ON_BOOT“, in the right-pane, enter “kvm kvm-intel kqemu” without quotes (”kvm kvm-amd kqemu” for AMD) in the setting box and click finish. Click OK on the confirmation window.
Now, we are all set to configure and run a guest OS on your openSUSE.
Installation of Windows guest paravirtual network drivers
opensuse:/kvm-disk # qemu-kvm -hda AD.img -cdrom /home/fs/Desktop/NETKVM-20081229.iso -net nic,model=virtio
Warning: vlan 0 is not connected to host network
AD.img is the image file where i had installed a windows 2008 to function as the Domain Controller
-cdrom /home/fs/Desktop/NETKVM-20081229.iso
The iso file contained the paravirtualized network drivers that i downloaded; when the Windows 2008 boot up, the cdrom drive will behave as if there is a CD containing the drivers needed for installation.
