Changes since v3: --Remove cpu_throttle_stop from mig_throttle_counter_reset. Changes since v2: --Add a function named packet_new_nocopy. --Continue to optimize the function of colo_flush_ram_cache. Changes since v1: --Reset the state of the auto-converge counters at every checkpoint instead of directly disabling. --Treat the filter_send function returning zero as a normal case. The series of patches include: Fixed some bugs of qemu crash. Optimized some code to reduce the time of checkpoint. Remove some unnecessary code to improve COLO. Rao, Lei (10): Remove some duplicate trace code. Fix the qemu crash when guest shutdown during checkpoint Optimize the function of filter_send Remove migrate_set_block_enabled in checkpoint Add a function named packet_new_nocopy for COLO. Add the function of colo_compare_cleanup Reset the auto-converge counter at every checkpoint. Reduce the PVM stop time during Checkpoint Add the function of colo_bitmap_clear_dirty Fixed calculation error of pkt->header_size in fill_pkt_tcp_info() migration/colo.c | 10 +++---- migration/migration.c | 4 +++ migration/ram.c | 83 +++++++++++++++++++++++++++++++++++++++++++++++++-- migration/ram.h | 1 + net/colo-compare.c | 25 +++++++--------- net/colo-compare.h | 1 + net/colo.c | 23 ++++++++++++++ net/colo.h | 1 + net/filter-mirror.c | 8 ++--- net/filter-rewriter.c | 3 +- net/net.c | 4 +++ softmmu/runstate.c | 1 + 12 files changed, 135 insertions(+), 29 deletions(-) Reviewed-by: Lukas Straub Tested-by: Lukas Straub
