I certainly wasn't suggesting that Yes. I was only pointing out that I think the persistent store should be in userspace. One approach would be to have another tree within the hypervisor that was the global persistent store. An advantage of that would be that it would be accessible by all domains without any special supporting software (like a TCP/IP stack). I think keeping the store in userspace has more advantages (mainly robustness and extensibility). It sounds like we're all in agreement though :-) Regards, Anthony Liguori > -- Keir > > ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
