[Bug 1569679] Re: lxc failed to do lxc-checkpoint again
Hi guys,
Can someone post a full log from a container where this fails? I'm
curious if it has the warning,
+ WARN("using host's /dev/null for container init's std
fds, migraiton won't work");
If so, it seems like the containers rootfs isn't set up correctly and
all is behaving as expected. If it doesn't have this warning, then it's
some other bug.

[Bug 1569679] Re: lxc failed to do lxc-checkpoint again
Strange. Basically it's using the host's /dev/null as described in 7a55c1576e2752e27882c52e34edcb8388120ad1, but I'm not sure why it would be doing that if you have a valid /dev/null in the container.

It has, and "echo 1 > /dev/null" works inside the container. Old lxc & criu version can make successful checkpoint but current version can't.

Right. I'm guessing your container doesn't have a proper /dev/null itself?

Do you have autodev turned off in the container without the container itself having a /dev/null?
