Hardware-based solutions that provide support for virtual machine creation and management via !rmware __________

Benefits of Virtual Machine (VM) include better efficiency in the use of the physical system resources

Containerization sits in between the OS and applications and incurs lower overhead, but potentially introduces greater security vulnerabilities

All containerized applications on a host share a common OS kernel

Each Virtual Machine (VM) includes an Operating System (OS), called the guest OS

A virtualization container runs on top of the host OS kernel and provides an isolated execution environment for applications

Like hypervisor-based VMs, containers aim to emulate physical servers

A technology that provides an abstraction of the resources used by some software which runs in a simulated environment (a)   called

Native virtualization systems are more common in clients, where they run alongside other applications on the host OS and are used to support app

Native virtualization systems are more common in clients, where they run alongside other applications on the host OS and are used to support applications for alternate operating system versions or types

In virtualized systems, the available hardware resources are

(a)  

Some principal functions performed by a hypervisor are

(a)  

Hypervisor Security should be

(a)  

Applications that run on standard operating systems but provide VMM features to guest operating systems

A recent approach to virtualization is known as container virtualization or application virtualization

Provides support for multiple distinct operating systems and associated applications on one physical system

(a)
