U

  • Unified Virtualization Platform

    Virtual management software that divides each computing resource into multiple VM resources.

  • UVP

    See Unified Virtualization Platform.

  • UVP Black Box

    A component that collects and stores kernel logs and diagnosis information provided by the diagnosis tool before the physical machine where the UVP (that is, dom0) is installed crashes. After the system crashes, the logs and information are exported for analysis.

V

  • VBD

    virtual block device

  • VFS

    See virtual file system.

  • VIF

    See virtual interface (VM NIC).

  • virtual disk

    A file in the host file system. For a customer operating system, it functions as a physical disk drive. The file can be configured on the host or a remote file system. After configuring a VM with a virtual disk, you can install a new operating system to the disk file without having to repartition a physical disk or restart the host. Virtual disks on the VMware Workstation can be mapped to the partitions on the host.

  • virtual file system

    A system that provides a versatile object-oriented interface for all file systems in the integrated file system.

  • virtual interface (VM NIC)

    An entity with an IP address that processes service data in a virtual device. In the virtual system, it is identified as vif.

  • virtual local area network

    An end-to-end logical network across different network segments and networks, constructed using the network management software based on the switching LAN. Network resources and users are logically divided based on a certain principle and a physical LAN is logically divided into multiple broadcasting domains (VLANs). The hosts on a VLAN can directly communicate with each other whereas different VLANs cannot. This efficiently suppresses broadcasting packets.

  • virtual machine

    One or more computer systems virtualized from a physical server.

  • VM IP address

    An IP address assigned to a VM, unlike the IP address assigned to a physical machine. The VM can communicate with other devices on the network using the IP address.

  • virtual memory

    Virtualized memory for a VM allocated based on the physical memory. Even if the memory is not physically contiguous, it is contiguous for the VM. The VM can randomly save data to and obtain data from its virtual memory without affecting the memory accessibility of other VMs on the same physical machine.

  • Virtual NIC

    An NIC for VMs, unlike an NIC for a physical machine. Multiple virtual NICs can be created for a single VM. The virtual NIC can connect to the physical NIC in bridge mode for data transmission.

  • Virtual Private Server

    The service for leasing servers to enterprises.

  • virtual server

    A device on which the operating system and applications run based on various virtualization technologies, unlike the original physical server. When using certain resources of the physical server, the virtual server is the same as the physical server for users. Both partitions and VMs are considered virtual servers.

  • Virtual Software Switch

    A device that is deployed on a computing node and performs the virtual network switching function for the VMs on the node.

  • virtual storage

    A technology used to uniformly manage multiple storage devices to provide storage systems featuring customized capacity, high reliability, and high I/O performance for users.

  • virtual switch

    A software program created on a physical server to implement data switching between VMs on the same or different servers.

  • virtualization technology

    A technology that enables a single physical server to operate multiple independent virtual OSs.

  • VLAN

    See virtual local area network.

  • VM

    See virtual machine.

  • VM high availability

    A feature that enables the O&M system to continuously monitor all physical hosts and automatically migrate all VMs off a faulty host.

  • VM migration

    A technology used to migrate VMs to another hardware resource for VM operations.

  • VM specifications

    A set of predefined VM attributes for creating VMs with unified specifications.

  • VM template

    A template used to create VMs that have the same specifications. A template is a VM in essence. A VM and a VM template can convert to each other as required. After a VM is converted to a template, only its isTemplate field is changed to true.

  • volume

    The logical storage volume of a VM, which can either be system volume or user volume.

  • VPS

    See virtual private server.

  • VSS

    See virtual software switch.

  • VT

    See virtualization technology.

Y

  • Yast

    A central management and installation tool in SUSE Linux.
