Maybe this bug/patch could be helpful:


Todd Deshane

Thank you! Apologies, I really should have googled that first. I just assumed that I had done something wrong.

While we're on this subject, I could use an opinion about something. I'd like to use a xen machine as a production database. The plan would be to run only one guest and give it most of the system resources. I read that disk partitions give better performance than files, which makes sense, but it also appears easier to clone and use files than partitions, and administration and maintainance time is certainly an issue. So the question is this: in this circumstance, with the entire machien dedicated to one guest, do you think that the performance difference is enough to warrant the use of a dedicated partition? How substantial is it?
