If enabled, QEMU can optimize migration when the destination is a QEMU process that runs on the same host as the source (as is the case for live upgrade). If the migration transport is a Unix socket, QEMU will flip RAM pages directly to the destination, so that memory is only allocated twice for the source and destination processes. Disabled by default. (since 1.8) Paolo
