Currently we cannot directly transfer a QTAILQ instance because of the limitation in the migration code. Here we introduce an approach to transfer such structures. We created VMStateInfo vmstate_info_qtailq for QTAILQ. Similar VMStateInfo can be created for other data structures such as list. When a QTAILQ is migrated from source to target, it is appended to the corresponding QTAILQ structure, which is assumed to have been properly initialized. This approach will be used to transfer pending_events and ccs_list in spapr state. We also create some macros in qemu/queue.h to access a QTAILQ using pointer arithmetic. This ensures that we do not depend on the implementation details about QTAILQ in the migration code.
