I<--rdma-pin-all> can be used with RDMA migration (i.e., when I<migrateuri>
starts with rdma://) to tell the hypervisor to pin all domain's memory at once
before migration starts rather then letting it pin memory pages as needed.
B<Note>: Individual hypervisors usually do not support all possible types of
migration. For example, QEMU does not support direct migration.
