What a timely question! Management is after me to quantify how many guests we can run on our 1 IFL for billing purposes. They want to carve it up into units so they know how many total we have, and therefore can charge per server. I don't see it going that way, as several of you have pointed out: it depends on the workload.
Anyone running in a data center and charging for their Linux servers? How are you approaching it? Do you have a flat fee per instance, or do you have a charge-back model? I'm curious and completely new at this aspect of z/VM management.
