Our assumption was that the question that came from KVM Forum was if muser can be used to achieve the same what we have now. We should have answered clearly yes to this question. We have not yet discovered major road blocks. At the moment, we are mostly engaged in learning the code and discussing the design, plus some coding to answer the specific questions. We understand that the best way to make a progress is to work with the upstream community on early stages and we agree with this and will present the proposal shortly for discussion. > Is there a work-in-progress muser patch series you can post to start the > discussion early?

At the moment we do not have the patches ready for the review. We have setup internally a milestone and will be sending that early version as a tarball after we have it completed. Would be also a meeting something that could help us to stay on the same page? > It's good that you are in touch with the muser developers (via private > discussion?
