Public bug reported: Hi, I opened an issue on github( https://github.com/lxc/lxd/issues/2110 ) about a failure during live migration of lxd container, this is the main error after executing the move command:
lxc move lnmp LXC2:migrated error: Error transferring container data: checkpoint failed: (00.014228) Error (sockets.c:129): Diag module missing (-2) (00.015240) Error (sockets.c:129): Diag module missing (-2) (00.016208) Error (sockets.c:129): Diag module missing (-2) (00.098007) Error (cr-dump.c:1600): Dumping FAILED. I followed this guide ( http://insights.ubuntu.com/2016/04/25/lxd-2-0 -live-migration-912/ ) and i also get the same error with stateful snapshots. lxc snapshot lnmp snap1 --stateful error: checkpoint failed So i'm assuming lxc move uses stateful snapshots and here where it fails the migration? That's the error i find on lxc.log: lxc 20160612130550.161 INFO lxc_criu - criu.c:exec_criu:387 - execing: /usr/sbin/criu dump --tcp-established --file-locks --link-remap --manage-cgroups --ext-mount-map auto --enable-external-sharing --enable-external-masters --enable-fs hugetlbfs --enable-fs tracefs -D /tmp/lxd_checkpoint_927931833 -o /tmp/lxd_checkpoint_927931833/dump.log -vvvvvv -t 22687 --freeze-cgroup /sys/fs/cgroup/freezer///lxc/lnmp --ext-mount-map /dev/console:console --external tty[8801:e] --force-irmap lxc 20160612130550.161 DEBUG lxc_commands - commands.c:lxc_cmd_handler:893 - peer has disconnected lxc 20160612130550.223 ERROR lxc_criu - criu.c:do_dump:866 - dump failed with 1 And on migration log: (00.048642) Collecting netns 9/22687 (00.048644) Switching to 22687's net for collecting sockets (00.049685) Warn (libnetlink.c:65): ERROR -2 reported by netlink (00.049973) Collected: ino 0x 209db5 family 2 type 1 port 3306 state 10 src_addr 127.0.0.1 (00.049990) Collected: ino 0x 2096d6 family 2 type 1 port 80 state 10 src_addr 0.0.0.0 (00.049997) Collected: ino 0x 209d82 family 2 type 1 port 22 state 10 src_addr 0.0.0.0 (00.050054) Collected: ino 0x 2092e7 family 2 type 2 port 68 state 7 src_addr 0.0.0.0 (00.050188) Collected: ino 0x 2096d7 family 10 type 1 port 80 state 10 src_addr :: (00.050198) Collected: ino 0x 209d84 family 10 type 1 port 22 state 10 src_addr :: (00.051625) Warn (libnetlink.c:65): ERROR -2 reported by netlink (00.051642) Warn (sockets.c:702): The current kernel doesn't support packet_diag (00.052596) Warn (libnetlink.c:65): ERROR -2 reported by netlink (00.052615) Warn (sockets.c:712): The current kernel doesn't support netlink_diag (00.052628) Unlock network If i reproduce the same operation with the container turned off i can copy\move without problems.
