Xen dmesg on a fully booted box is ~400 lines on my local box. That might get quite longer if you have a box with a lot of memory region, or a lot of CPUs. > There was enough for alarms to trigger. That's fine, but without pointing out which information is sensitive, it's very unlikely such concerns will ever get fixed. Could you at least go over the log and point out the first instance of such line that you consider contains sensitive information? The primary way we have to diagnose and solve issues reported by users is based on Xen dmesg, so if it's impossible to provide it for privacy reasons that's an issue that we need to address.
