Dear Andy,

Thanks for the reply.

Thanks, thats indeed excellent news. May i ask is the snapshot stable enough to use on the production box (sorry if it sounds a stupid question to you). I am using 3.0 stable rpm from xensource on centos 4.1 right now.

This will give the problem of the vifname changing everytime and hence loosing track of the vif to whom the bandwidth should be accounted to.

Is it possible for you to direct me to some examples ? It will really help.
