Differences between revisions 21 and 24 (spanning 3 versions)

While benchmarks are a very difficult exercice and as such the results must be considered carefully, they are still interesting to compare the respective performance between the solutions for different workloads.

This page will try to keep an eye on the relative performance of Xen and KVM. Until 2.6.25, virtio was not part of the mainstream linux kernel, so the tests compared performance of HVM systems (the guest system was an "unmodified OS").

29 Jul 2008

Setup is the same as the tests from 22 Jul 2008 below. Please note that unless specified otherwise, the VMs use a disk image on the host.

Test consist of a single run of bonnie++ v1.03b (default package from ubuntu 8.04).

All tests where realised on the same system: AMD X2 4400+/4GB RAM/sata drive.

Host is running Ubuntu Desktop 8.04 amd64, kernel 2.6.24-19-generic (when values are given for the host, it was started with mem=3072M) All the runs with the guests use the same image based on a basic install of ubuntu server 8.04 amd64, with 3072M and smp 2.

$/!\$ The VM image use a disk image on the host. It was reported to me that this severly impacts IO performances.

Thanks for Dan Berrange who pointed me on xen.org instead of xensource.com as a source of download for the latest Xen.

The tests consists of the compilation of a linux kernel 2.6.24 with allnoconfig (make allnoconfig && time make). The host hardware is a 1.86Ghz Intel Core2duo.

unmodified VM: 64bits Debian Etch

The first two tests run the same Virtual Machine with an unmodified 64bits Debian Etch.

paravirtualised VM: 64bits Debian Etch with xenified kernel

The following test runs on the same hardware than the previous one. The kernel used in the DomU is the same as in Dom0:

11 Feb 2008

For the following 2 tests, the system is an Intel core 2 duo 2.4Ghz w/ 2GB RAM running the latest available versions:

for Xen: opensource Xen 3.1.0 (from xen.xensource.com) + Dom0 kernel based on kernel.org 2.6.18
for KVM: kvm-60 on a 2.6.23

The guest used in both case is the exact same VM (non-paravirtualised 64 bit Debian etch with 256 MB RAM).
