Using CRIU with nested LXC containers

[alexfrolov]

Hi!

I am considering using CRIU for checkpoint/restore of nested LXC containers. Do I understand it right that in this case CRIU should be called inside parent container?

For example, as far as I understood CRIU is using mnt namespace of the CRIU process (/proc/self/ns/mnt) to resolve external mountpoints for target process, so this means that CRIU wont be able to work from the host level in case target process is running in nested container. Is that correct?

Thanks, Alex
