Hi Hailiang,
With version 2, the code in migration/ram.c
+if (migration_incoming_colo_enabled()) {
+if (migration_incoming_in_colo_state()) {
+/* In COLO stage, put all pages into cache temporarily */
+host = colo_cache_from_bloc
This patch will reduce the downtime of VM for the initial process,
Privously, we copied all these memory in preparing stage of COLO
while we need to stop VM, which is a time-consuming process.
Here we optimize it by a trick, back-up every page while in migration
process while COLO is enabled, thoug
