I'm planning my first production xen instance. My question is about how to determine how much memory I need for Dom0.

The scenario is simple. I have a machine with 12G of ram. I want to run a single web server as a DomU, giving it as much cpu and memory as possible. The docs say that Dom0 needs a minimum of 512M. Am I likely to need more than that? Is there a method of figuring what a Dom0 needs? What factors affect this? What's the realistic minumum for a machine with a lot of network traffic?

If this question is answered elsewhere and I missed it, feel free to curtly point me in the right direction. Any help is appreciated.
