Since 16bcb3 we have a regression. The hard_limit is set
unconditionally. By default, the limit is zero. Hence, if user hasn't
configured any, we set the zero in cgroup subsystem making the kernel
kill the corresponding qemu process immediately. The proper fix is to
set hard_limit iff user has configure any.
