We run a huge number of xen instances at work. Performance is great, although we've ended up compiling our own kernels and not using the stock kernels for it.
If you are interested, you could swing by my home office sometime and I could show you how things are set up and how it works.
We might be giving a presentation about the setup at LISA next year. I'd mentioned I could give a presentation about it sometime to the group, though I've been lazy about actually doing so. The upcoming Lisa thing might provide me with some motivation to actually do so.
