Hi, this patch implements live migration and shadow mode. When shadow mode is enabled, Dirty bit is virtualized. psr.da is *not* yet virtualized because it is not that simple and because Linux doesn't use it. This is a first implementation. I have only tested live migration within the same machine (127.0.0.1 !). I will do more tests and performance improvement as soon as I have a good configuration to do it. Tested by doing a live migration on the same node, save & restore tested. Tristan.
