I've looked at ct migration between 2 ubuntu 16.04 hosts today, and had some interesting problems; I find that migration of stopped containers works fairly reliably; but live migration, well, it transfers a lot of data, then exits with a failure message. I can then move the same container, stopped, with no problem.
The error is the same every time, a failure of "mkdtemp" - root@ronnie:~# lxc move third lxd: error: Error transferring container data: restore failed: (00.033172) 1: Error (cr-restore.c:1489): mkdtemp failed crtools-proc.x9p5OH: Permission denied (00.060072) Error (cr-restore.c:1352): 9188 killed by signal 9 (00.117126) Error (cr-restore.c:2182): Restoring FAILED. root@raskolnikov:~# lxc move third lxd2: error: Error transferring container data: restore failed: (00.039099) 1: Error (cr-restore.c:1489): mkdtemp failed crtools-proc.a3U2t5: Permission denied (00.063015) Error (cr-restore.c:1352): 1771 killed by signal 9 (00.115261) Error (cr-restore.c:2182): Restoring FAILED. root@ronnie:~# lxc move third lxd: error: Error transferring container data: restore failed: (00.034542) 1: Error (cr-restore.c:1489): mkdtemp failed crtools-proc.gee5YS: Permission denied (00.059955) Error (cr-restore.c:1352): 9274 killed by signal 9 (00.109272) Error (cr-restore.c:2182): Restoring FAILED. Thanks for any pointers you can provide - PS - on a side note, I'd originally set up the new box with a separate /var partition on btrfs. As a result, "criu check" would die instantly with a segmentation error. After putting /var back on / (ext4) criu check produces the message "Looks good."
