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)
