Summary


LXC supports various backing stores for its filesystem. In this chapter, we explored how to use the LVM, Btrfs, and ZFS backing stores to create COW snapshots. We also looked into how to create block devices from regular files for testing purposes.

We demonstrated how to autostart containers, create hooks that will execute programs during the life cycle of the instance, and how to expose directories and files from the host OS to LXC.

LXC uses the cgroup mechanism for controlling and allocating resources to containers. Changes to these resources are stored in the config file and can be persisted if the need arises. We explored ways of doing that with the provided toolset.

Finally, we introduced a different way of creating and managing LXC with libvirt and the virsh command.

In the next chapter, you'll have a look at how to create and manage containers using the LXC APIs and libvirt bindings for Python.
