| H A D | postcopy-ram.c | 2d49bacd Sat Oct 05 19:02:48 CDT 2019 Wei Yang <richardw.yang@linux.intel.com> migration/postcopy: postpone setting PostcopyState to END
There are two places to call function postcopy_ram_incoming_cleanup()
postcopy_ram_listen_thread on migration success
loadvm_postcopy_handle_listen one setup failure
On success, the vm will never accept another migration. On failure,
PostcopyState is transited from LISTENING to END and would be checked in
qemu_loadvm_state_main(). If PostcopyState is RUNNING, migration would
be paused and retried.
Currently PostcopyState is set to END in function
postcopy_ram_incoming_cleanup(). With above analysis, we can take this
step out and postpone this till the end of listen thread to indicate the
listen thread is done.
This is a preparation patch for later cleanup.
