hyper_kill_container_processes() depends on container->ns,
but hyper_release_exec() may calls hyper_cleanup_pod() which
calls hyper_cleanup_containers() and then hyper_cleanup_container(),
and container->ns is closed in hyper_cleanup_container().
It cause hyper_kill_container_processes() failed to
stat the container->ns.

it can be triggered via 'hyperctl run -t ubuntu' and then 'exit'
in the shell of the container.
so we have to swap the order of hyper_kill_container_processes
and hyper_release_exec().

You can get the binary installer of HyperContainer and HyperStart through The Hyper Page
Build from source
clone this repo, and make sure you have build-essentials installed. Go into the working copy and
> ./autogen.sh
> ./configure
> make
Then you can find hyper-initrd.img in the build directory, together with a pre-built kernel.
If you want to get the boot disk file for VirtualBox, please reconfigure with flag --with-vbox,
> ./configure --with-vbox
