In the case of migration, we don't care about the layout of physical memory. We just want to look at memory from phys_ram_base .. ram_size. The problem is that we encode physical addresses in the migration protocol as 32-bit values. We'll need to figure out a way to switch to encoding PFNs while maintaining backwards compatibility with the current code. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=1971512&group_id=180599 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
