I should have mentioned that I tried only QEMU driven migration within the same host using wp3-postcopy branch of your tree. I don't see the above issue. (qemu) info migrate capabilities: xbzrle: off rdma-pin-all: off auto-converge: off zero-blocks: off compress: off x-postcopy-ram: on Migration status: completed total time: 39432 milliseconds downtime: 162 milliseconds setup: 14 milliseconds transferred ram: 1297209 kbytes throughput: 270.72 mbps remaining ram: 0 kbytes total ram: 4194560 kbytes duplicate: 734015 pages skipped: 0 pages normal: 318469 pages normal bytes: 1273876 kbytes dirty sync count: 4 I will try migration between different hosts soon and check.
