How did you create the container tree? Did you copy the host's root into
a subdirectory? Note that you need to make sure that /etc/machine-id is
unique. When you copy the same image into multiple directories you hence
need to regenerate the machine-id.

Alternatively, remove the file in the container, as it will then create
a new machine id on boot automatically, and store in the file.
