I’ve just tried:
1) installed kvm and qemu through Yast (they are already available in the distribution, i.e. no zypper commands required).
I was not able to find “kqemu-kmp-default”, hence I didn’t install kqemu.
3) checked for the modules with “lsmod | grep kvm”
3) with Yast, added “kvm kvm-amd kqemu” in /etc/sysconfig (although kqemu is missing !!)
4) created the image
mkdir /vms
cd /vms
qemu-img create -f qcow xp_disk.img 10G
5) installed XP
qemu-system-x86_64 -hda /home/vms/xp_disk.img -cdrom /home/iso/WinXP_Pro_SP2_IT.iso -boot d -m 512
6) started XP, with either:
qemu-system-x86_64 -hda /home/vms/xp_disk.img
or
qemu-kvm -hda /home/vms/kubu_disk.img
Both commands work. With the latter, XP seems to be faster, BUT not as faster as expected !!

I guess that with kqemu it should be faster !
Could someone tell me where can I retrieve it for OpenSUSE 11.2 ?

Thanks

Have you tried kvm virtualization on OpenSuSE 11.2? TU

## so i will again write a steps ::

zypper ar http://download.opensuse.org/repositories/Virtualization:/KVM/openSUSE_11.0 KVM
zypper refresh
zypper in -r KVM kvm
zypper in qemu
modprobe kmp
modprobe kmp-amd ## owners of intel need to load kmp-intel instead
lsmod | grep kmp ## check if loaded
usermod -A kvm username ## need to reload user if active to make changes affect
qemu-img create -f raw /path/to/disk.img 2G
qemu-kvm -hda /path/to/disk.img -cdrom /path/to/bootable.iso -boot d -m 128 -cpu athlon -localtime

## you can order these modules be loaded during boot by editing /etc/sysconfig/kernel in variable MODULES_LOADED_ON_BOOT=foo ..

## JFYI :: qemu-system-x86_64 binary used in article above is provided by package:

# rpm -qif `which qemu-system-x86_64` | sed ‘/^Name/!d’
Name : qemu

## and have nothing to do with KVM based virtualization ..

*** sorry ..
modprobe kmp-amd ## should be there ^^ .. not `modprobe kmp-pae`

NO .. there is major disinfo .. steps in this article does not lead to run KVM based guest, but pure software based quest based on qemu..

to run machine under KVM, proceed as follows ::

## add with alias KVM needed repo and install packages
zypper ar http://download.opensuse.org/repositories/Virtualization:/KVM/openSUSE_11.0 KVM
zypper refresh
zypper in -r KVM kvm
zypper in qemu

## load and check modules .. in my case amd
modprobe kmp
modprobe kmp-pae
lsmod | grep kmp

## add suggested user into kvm group to can use kvm as non-root
usermod -A kvm

## create disk and run guest ..
qemu-img create -f raw /path/to/disk.img 2G
qemu-kvm -hda /path/to/disk.img -cdrom /path/to/bootable.iso -boot d -m 128 -cpu athlon -localtime

<< package qemu is needed only for qemu-img binary .. it is not necessary to add qemu repo as well as installing qemu-modules

please fix it in article ..

zypper ar http://download.opensuse.org/repositories/Virtualization:/Qemu/openSUSE_11.0/ “QEMU Virtualization”

Seems not to work until you remove the space in “QEMU Virtualisation”…
The alias it seems has to be one word only.
This is true in Yast and at the command prompt.
