Error in LXD live migration


#1

Trying to live migrate containers between two machines. I saw the following errors.

$ lxc copy magikarp002:oddish/oddish-bck-20180203021401 test
error: Failed container creation:

Then I tried to do a stateful stop for this container

$ lxc snapshot oddish --stateful
error: snapshot dump failed

However, if I stop the container and then “lxc copy” between two machines could work successfully.

This is the failed migration log file.

Using this live migration for a year now, it was working perfectly. This function started to fail after some Ubuntu upgrade several weeks ago.

I saw similar issue reported https://github.com/checkpoint-restore/criu/issues/439

Any hint about this issue?
Thanks a lot


(Stéphane Graber) #2

Protocol 58, assuming that uses normal protocol numbering would be IPv6 ICMP.
So something in the container may now be holding such a socket open, causing CRIU to fail to serialize the container?


#3

Thank you. After I disabled ipv6 inside the container, I saw another error message.
