[Xen-devel] Potential MS Thesis ? - (Re: questions about ballooning)
Hi All (Mark, Weiming, Daniel), I''m a masters student with some prior experience with Xen and am looking for a project for my MS thesis. After searching through this mailing list I found the following mail trail (read below) about automatic memory balancing and was wondering if anyone has taken on this project or if it is still open ? I would be happy to make this my MS thesis work (pending adviser approval). Also, I had an idea for a distributed load-balancing system for a Xen based cluster/farm and was wondering if this has already been done or not, any feedback, advice or references would be appreciated.
