Summary

In this chapter, we introduced the different modes of server virtualization, the reasons for using it, and how it actually works. We also caught a glimpse of the development on server virtualization by knowing the background technologies. Besides that, we learned the features and strengths of the different hypervisors on the market. Moreover, we went through some basic administration techniques of Proxmox, including the creation of virtual machines, importing OpenVZ templates, and viewing a guest system via the web console. Most importantly, we learned how to distinguish KVM and OpenVZ, which affects our decision during VM creation, for example, security versus performance.

In the next chapter, we are going to learn some concepts on high availability and the introduction of the Proxmox cluster.
