error: snapshot dump failed

[aditya]

To start live migration using LXD in docker my experimental setup is as follows:

Physical machine OS: Ubuntu 16.04
Docker version 17.06.0-ce, build 02c1d87
lxc --version 2.0.11
lxd --version 2.0.11
criu --version Version: 2.6

After successful installation of container named 'c1' i run the following command to save the current states of the container to disk:

 sudo lxc snapshot c1 checkpoint-2 --stateful

 But it gives following errors:
error: snapshot dump failed
(00.260241) Error (criu/sk-netlink.c:73): The socket has data to read
(00.260268) Error (criu/cr-dump.c:1313): Dump files (pid: 9158) failed with -1
(00.303791) Error (criu/cr-dump.c:1628): Dumping FAILED.

Any, help will be appreciated. Solutions can be emailed directly at: <email address hidden>

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.17 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.
