[2 months] Does this live migration include migration of open files, sockets, pipes etc ? Or is this limited to the process migration. What I mean is : If I have a VM running a web server, and I try to migrate, will I lose the connection, or will it continue seamlessly? Some other questions that arise if the above is true are: 1) If it does, will the client application/server application change in any way ? 2) How do the TCP bytestreams get synchronized after migration? 3) How big a state do you envision you would need to transfer ?
