    shared nothing live migration

    Shared nothing live migration is a term used to describe the process of moving a virtual machine (VM) from one physical host to another, without the need for clustering or a common shared storage location.

  • smart paging

    Smart paging is an advanced version of memory paging in Windows Server 2012 Hyper-V, where a virtual machine is capable of temporarily using hard disk space to supplement shortages of solid-state memory.

  • T

    transparent page sharing

    Transparent page sharing (TPS) is a memory management technology in virtualization.

  • V

    virtual file system (VFS)

    A virtual file system (VFS) is programming that forms an interface between an operating system's kernel and a more concrete file system. 

  • virtual hard drive

    A virtual hard drive file is a container file that acts similar to a physical hard drive.

  • virtual memory ballooning

    Virtual memory ballooning allows a physical host to recapture unused memory on its guest virtual machines and allocate the resource where needed.

  • virtual storage appliance (VSA)

    A virtual storage appliance (VSA) is a storage controller that runs on a virtual machine(VM) to create shared storage without the cost of additional hardware. 

  • virtual to physical (V2P)

    Virtual to physical (V2P) is a term that refers to the migration of an operating system (OS), application programs and data from a virtual machine or disk partition to a computer's main hard disk... (Continued)

  • Virtual to virtual (V2V)

    Virtual to virtual (V2V) is a term that refers to the migration of an operating system (OS), application programs and data from a virtual machine or disk partition to another virtual machine or disk partition... (Continued)

  • virtualization

    Virtualization is the creation of a virtual -- rather than actual -- version of something, such as an operating system (OS), a server, a storage device or network resources.

  • VM BIOS (virtual machine basic input/output system)

    A VM BIOS (virtual machine basic input/output system) is the set of instructions that controls the booting process of a virtual machine.

  • VMDK file (virtual machine disk file)

    VMware Virtual Machine Disk File (VMDK) is a format specification for virtual machine (VM) files. A file with a .VMDK file extension is essentially a complete and independent virtual machine.

  • VMware memory overcommit

    Memory overcommit is the memory allocation feature for Vmware.

  • VMware Tools

    VMware Tools is an optional, free set of drivers and utilities that enhances both the performance of a virtual machine’s guest operating system and interaction between the guest and the host.

  • VSMP (virtual symmetric multiprocessing)

    VSMP (virtual symmetric multiprocessing) is a method of SMP (symmetric multiprocessing) in which two or more virtual processors are mapped inside a single virtual machine or partition... (Continued)
