A. It must be loaded into the kernel of the host system in order to use the virtualization extensions of the host system's CPU.

B. It must be loaded into the kernel of the host system only if the console of a virtual machine will be connected to a physical console of the host system.

C. It must be loaded into the kernel of each virtual machine that will access files and directories from the host system's file system.

D. It must be loaded into the kernel of each virtual machine to provide paravirtualization which is required by KVM.

E. It must be loaded into the kernel of the first virtual machine as it interacts with the KVM bare metal hypervisor and is required to trigger the start of additional virtual machines.

A. It is a hypervisor optimized for the usage in embedded systems based on the ARM CPU architecture.

B. It automates the installation of a virtual machine according to a configuration file describing the desired VM.

C. It monitors the functionality of a virtual machine and restarts the VM in case of failure.

D. It migrates virtual machines automatically between host systemsto distribute the load of all virtual machines equally to all hosts involved.

A. Hardware based virtualization requires special support in the host system's hardware which is present in all recent x86-based computers.

B. Hardware based virtualization relies on the host system's processor to call the hypervisor when critical instructions are executed by a virtual machine.

C. Hardware based virtualization is not available on x86-based CPU architectures and requires special virtualization host hardware.

D. Hardware based virtualization implements a whole machine in software and therefore can run virtual machines of a given hardware platform on an arbitrary host system.

A. Create filesystems during the installation of new VM guest operating systems.

B. Ensure isolation and eliminate any interference between virtual machines.

C. Map the resources of virtual machines to the resources of the host system.

D. Provide host-wide unique PIDs to the processes running inside the VMs in order to ease interprocess communication between virtual machines.

E. Manage authentication to network services running inside a virtual machine.
