Which of the following statements about KVM virtualization is incorrect?

The statement that suggests "Libvirt + QEMU can constitute a set of virtualization solutions" is deemed incorrect because of a fundamental understanding of the roles of these components in a virtualization environment.

Libvirt is a toolkit that facilitates the management of virtualization technologies, including hypervisors. Its primary purpose is to provide a consistent API for interacting with various virtualization technologies, simplifying the management of both guests and host systems. QEMU, on the other hand, is an open-source machine emulator and virtualizer that can work standalone or alongside KVM to enable full system emulation and virtualization.

While Libvirt is often used in conjunction with QEMU to manage virtual machines (VMs), stating that they together constitute a set of virtualization solutions overlooks the fact that Libvirt does not perform the actual virtualization or emulation tasks—it enhances management capabilities instead. Its role is more administrative, allowing for easier interaction and control over resources managed by QEMU or KVM.

The other statements accurately describe the roles of their respective components: the KVM module's function in CPU and memory allocation, the cooperative function of KVM + QEMU in providing virtualization solutions, and the specific role of QEMU in handling I/O operations, which includes functioning as a file and network I
