Virtualization 1
The Environment it creates For the VM is essentially identical to the original (hardware) Physical Machine.
what is Fidelity
The VMM must have complete control of the system resorurces.
what is Isolation or safety
There should be alittle or no difference between the VM and a physical equivalent
what is Performance
what is Virtualization
what is Virtualization is a disruptive technology, shattering the status quo of how physical computers are handled, and how services are delivered and also how much budgets are allocated.
Originally called a virtual machine manager, its a layer if software that is installed between an operating system and the virtual machine or can also be directly connected to the hardware or bare -metal that provides the environment which a Vm operates
what is Hypervisor
A data file in an industry standard format that contains the exact image of an optical disk like a CD or DVD, used in the context to contain operating system or application files for installation.
what is ISO Image
A virtual machine or vm that runs on a host server
what is a guest server
An open source operating system, usually available for low or no cost, it runs on a variety of hardware, including mainframe computers, servers, desktops, mobile devices and other commercial appliances, such as cable/satellite boxes and video game counsels
what is Linux
A set of files that preserve the state of a vm at a given point in time so that you can revert back to the given state is called what
what is snapshot
A combination of device drivers and processes that enhance the users experience with a virtual machine, it also helps with vm performance.
what is vmare tools
A computer server without any operating system software installed is called what
what is bare-metal
An exact copy of a virtual machine.
what is a clone
the practice of of condensing multiple physical servers into one server through the use of virtualization
what is consolidation
A memory optimization technique that puts memory pages together and stores them in a cache rather then swapping them from memory to disk storage
what is compression
one of the leading providers of Linux distribution that makes it profits from support rather than license sales.
what is Red Hat Enterprise Linux
A process that allows thee hypervisor to reclaim physical memory pages by forcing the virtual machine operating system to flush memory pages to disk
what is ballooning
The core or brain of a computer where the user and system commands are executed. Computers today use microprocessors.
what is CPU or Central processing unit.
A Unix or linux program that runs as a backround process, and typically perform certain system task such as system scheduler or managing ftp capabilities
what is Daemon
Hardware and software solutions and implementations that allow server to lose one or more components to a failure without data loss or service interuptions
what is FT or Fault Tolerance
Hardware and software solutions and implementations that provide greater uptime and resiliency for a computing infrastructure
What is HA or High Availability
