* migration: Poison ramblock loops in migrationDr. David Alan Gilbert2018-06-151-1/+3
| | | | | | | | | | | | | The migration code should be using the RAMBLOCK_FOREACH_MIGRATABLE and qemu_ram_foreach_block_migratable not the all-block versions; poison them so that we can't accidentally use them.

It is not a command suitable for QMP interface. So only HMP interface is provided for it.
