For APT use the <code>--no-install-recommends</code> parameter is to avoid asciidoc pulling in a lot of dependencies.

Also read about [[ZDTM test suite]] if you will run CRIU tests, those sources need other deps.

Linux kernel v3.11 or newer is required, with some specific config options turned on. Various advanced CRIU features might require even newer kernel. So the first thing to do is to [[Checking the kernel|check the kernel]] by running <code>criu check</code>. At the end it should say "Looks OK", if it doesn't the messages on the screen explain what functionality is missing. If your distribution does not provide needed kernel, you might want to [[Linux kernel|compile one yourself]].
You can then try running the [[ZDTM Test Suite]] which sits in the <code>tests/zdtm/</code> directory.
