The latest version of the Open vSwitch now includes an integrated sFlow agent providing visibility in Linux, Xen/XenServer, KVM and Virtual Box environments:
http://openvswitch.org/ There is some information on configuring sFlow on the vSwitch on the sFlow blog: http://blog.sflow.com/2010/01/open-vswitch.html You will need to download the latest unstable version of the code to try out sFlow. If you find any problems, please report them so that they can be fixed before the stable production release. Peter
