It's all about storage!
Similar to virtual network infrastructure, we need a storage backend to create and save the virtual disks. There is an option to choose a wide variety of storage solution is as backend for virtual machines, from normal file-based storage to logical volume managed storage, gluster container, and many more. Storage backend is created and managed using the libvirt storage API and is called a "storage pool".
In this section, you will learn how to work with unmanaged and managed storage. You will also see how to create storage pools and volumes, including some of the newer options, such as ceph block storage, which allows us to create really large sized virtual disks and attach them to a virtual machine. You will also learn how to attach multiple disks to a single VM.
Working with unmanaged storage
Storage, which is not directly controlled and monitored by libvirt, is still used with virtual machines and is called unmanaged storage. This means that you can straightforwardly...
