What is the need for a shadow page table (One or two brief sentences.pdfSIGMATAX1
What is the need for a shadow page table? (One or two brief sentences please)
Solution
Virtualization allows multiple operating system instances to run concurrently on a single
computer. Virtualization is the creation of a virtual rather than actual version of something, such
as an operating system, a server, a storage device or network resources.
Virtualization is where the framework divides the resource into one or more execution
environments Even something as simple as partitioning a hard drive is considered virtualization
because you take one drive and partition it to create two separate hard drives.
Types of virtualization:
Storage virtualization: is the pooling of physical storage from multiple network storage devices
into what appears to be a single storage device
Data virtualization: is abstracting the traditional technical details of data and data management,
such as location, performance or format..
Network virtualization: is a method of combining the available resources in a network by
splitting up the available bandwidth into channels, each of which is independent from the others.
Server virtualization: the partitioning a physical server into smaller virtual servers.
Shadow Tables are objects used to improve the way machines, networks and programs handle
information.
Shadow page tables are used by the hypervisor to keep track of the state in which the guest
thinks its page tables should be.
The guest can\'t be allowed access to the hardware page tables because then it would essentially
have control of the machine. So, the hypervisor keeps the \"real\" mappings guest virtual -> host
physical in the hardware when the relevant guest is executing, and keeps a representation of the
page table..

2. Introduction
Virtualization is creating a virtual version of something,
including virtual computer hardware platforms, storage
devices and network resources.
Example: If you were to partition a basic hard drive to
create two hard drives, then you would have two
‘virtualized hard drives’, technically there is a single
hard drive that was digitally separated into two.
3. Benefits
Consolidation : an approach to the efficient usage of computer resources in order
to reduce the total number of resources that an organization requires.
Redundancy : duplication of critical components of a system with the intention of
increasing reliability of the system
Migration : process by which a running virtual machine is moved from one
physical host to another, with little or no disruption in service
Centralized management : process of managing all the OS from one point
5. Hardware/Server Virtualization
Hardware/Server Virtualization is the most common type of virtualization as
it provides advantages of hardware utilization and application uptime.
The basic idea is to combine many small physical servers into one large
physical server, so that the processor can be used more effectively and
efficiently.
The operating system that is running on a physical server gets converted
into a well-defined OS that runs on the virtual machine.
The hypervisor controls the processor, memory, and other components by
allowing different OS to run on the same machine without the need for a
source code.
6. Desktop Virtualization
Desktop virtualization is the concept of separating the logical desktop
from the physical machine.
As one can access remotely, you are able to work from any location and
on any PC.
Provides the work convenience and security.
Provides a lot of flexibility for employees to work from home or on the go.
Protects confidential data from being lost or stolen by keeping it safe on
central servers.
7. Software Virtualization
Software Virtualization provides the ability to the main computer to run
and create one or more virtual environments.
Used to enable a complete computer system in order to allow a guest OS
to run. For instance letting Linux to run as a guest that is natively running
a Microsoft Windows OS
Types:
Operating system-level virtualization - hosting of multiple virtualized
environments within a single OS instance.
Application virtualization and workspace virtualization - hosting of individual
applications in an environment separated from the underlying OS.
Service virtualization - emulating the behaviour of dependent (e.g., third-party,
evolving, or not implemented) system components
8. Memory Virtualization
Memory virtualization is aggregating random-access memory(RAM)
resources from networked systems into a single memory pool
Memory Virtualization introduces a way to decouple memory from the
server to provide a shared, distributed or networked function.
Enhances performance by providing greater memory capacity without any
addition to the main memory. That’s why a portion of the disk drive serves
as an extension of the main memory.
Implementation :
Application-level integration – Applications running on connected computers
directly connect to the memory pool through an API or the file system.
Operating System Level Integration – The operating system first connects to
the memory pool, and makes that pooled memory available to applications.
9. Storage Virtualization
Storage virtualization is the process of completely abstracting logical
storage from physical storage
Distributed file system, any file system that allows access to files from
multiple hosts sharing via a computer network
Virtual file system, an abstraction layer on top of a more concrete file
system, allowing client applications to access different types of concrete
file systems in a uniform way
In general, there are two types of storage virtualization:
Block- It works before the file system exists. It replaces controllers and takes
over at the disk level.
File- The server that uses the storage must have software installed on it in
order to enable file-level usage.
10. Data Virtualization
Data virtualization, the presentation of data as an abstract layer,
independent of underlying database systems, structures and storage.
Database virtualization, the decoupling of the database layer, which lies
between the storage and application layers within the application stack
over all.
Without any technical details, you can easily manipulate data and know
how it is formatted or where it is physically located. It decreases the data
errors and workload.
11. Network Virtualization
Network virtualization is creation of a virtualized network addressing space
within or across network subnets
Virtual private network (VPN) is a network protocol that replaces the actual
wire or other physical media in a network with an abstract layer, allowing a
network to be created over the Internet
The intended result of network virtualization provides improved network
productivity and efficiency.
Two categories :
Internal: Provide network like functionality to a single system.
External: Combine many networks, or parts of networks into a virtual unit.
12. Conclusion
Virtualization provides an easy way to set up new virtual servers so you don’t
have to manage a lot of them. Keeping track of where everything – and how
your physical resources are used for virtual resources – is vital, so shop for
solutions that have easy-to-use tools that help you measure and monitor
usage.
Virtualization isn’t a magic bullet for all. But in most cases, the
productivity, efficiency, security and cost advantages outweigh any issues,
and thus, virtualization is continuously gaining popularity.
