In this chapter, we introduced and configured various Open Source storage concepts for libvirt. We also discussed industry-standard approaches, such as iSCSI and NFS, as they are often used in infrastructures that are not based on KVM. For example, VMware vSphere-based environments can use FC, iSCSI, and NFS, while Microsoft-based environments can only use FC and iSCSI, from the list of subjects we covered in this chapter.
The next chapter will cover subjects related to virtual display devices and protocols. We'll provide an in-depth introduction to VNC and SPICE protocols. We will also provide a description of other protocols that are used for virtual machine connection. All that will help us to understand the complete stack of fundamentals that we need to work with our virtual machines, which we covered in the past three chapters.
