Joelle, please clarify which QEMU version has the problem you're fixing and how to reproduce it. I only tested latest staging branch so far. There was a report in the past about potentially wrong mem region refcounting, but it was reported for a very unstable WIP code and I couldn't reproduce the problem. We can always revert patch and try again later if you're short on time. -- Best regards, Dmitry
