Hm... The error ENOENT appears either because either a) criu is run not from user or 
inside user namespace or b) the dirname of the path in question doesn't exits.

Can you find out which of the above is your case?

This is because /dev/console is bind-mounted from outside. Should be fixed by the
--ext-mount-map option.
