It's very similar to the trick that NEMU uses for templating.
With the x-ignore-shared-ram migration capability enabled, migration
will not write to the migration stream any RAM block that had the
shared=on flag on the qemu commandline. So you should then be able
to restart from the migration stream and existing RAM image.
