In this chapter, we learned about LXC containers, how to create and manage them, and the difference between unprivileged and privileged containers. We also learned how to convert OpenVZ containers to LXC containers and use them in Proxmox VE 4.0 or later versions. Despite not having the live migration ability, an LXC container is still a better choice of containerization than OpenVZ and works very well in a Proxmox environment.

In the next chapter, we will see some advanced features of network components in a Proxmox cluster. We will learn the benefits of a virtual network, what Open vSwitch is, and why we should use it in a virtual environment.
