Ok, I've been trying to produce a situation where this is necessary
but I couldn't. Can you paste your lxc configuration file?

-V isn't an argument to lxc-checkpoint. (Perhaps you mean -v? That
/shouldn't/ affect things, it is just logging.) What happens when you
don't pass -d?

No, those should work. Can you show the output of ps auxf?

That's not needed, it is an old criu option (CRIU's wiki is outdated).

The log itself is generated by criu, so that is probably a question
for the criu list, not the lxc list :)
