VM Compatibility Level
A virtual machine compatibility level determines the virtual hardware features available to a guest.
View definitionVM Escape
A VM escape is a security vulnerability that lets code in a guest cross the isolation boundary into the host or hypervisor.
View definitionVM Generation ID
VM Generation ID helps supported guest systems detect that a VM has been restored or cloned, avoiding unsafe state reuse.
View definitionVM Hardware Version
A VM hardware version specifies virtual device capabilities and the minimum compatible hypervisor generation.
View definitionVM Template
A VM template is a prepared reference for deploying consistent virtual machines, with separate customization for each new instance.
View definitionVMDK
The virtual disk format commonly used by VMware.
View definitionVMFS
VMFS, Virtual Machine File System, organizes VM files on VMware datastores backed by block storage.
View definitionVMkernel
VMkernel is the core of VMware ESXi responsible for scheduling, memory, storage, and host resource management.
View definitionVMkernel Adapter
A VMkernel adapter provides an IP interface on an ESXi host for management, vMotion, or storage services.
View definitionVMkernel Port
A VMkernel port connects ESXi host services to a virtual switch and assigned network configuration.
View definitionvMotion
VMware vMotion moves a running virtual machine between compatible ESXi hosts with a typically brief service interruption.
View definitionvMotion Network
A vMotion network carries migration traffic when VMware transfers a running virtual machine between hosts.
View definitionVMware ESXi
ESXi is VMware’s bare-metal hypervisor for running and isolating virtual machines on a physical server.
View definitionVMware HA
A function that automatically restarts VMs on another host after ESXi failure.
View definitionVMware RDM
A VMware mechanism allowing a VM to access almost directly to a LUN SAN.
View definitionVMware Tools
VMware Tools supplies guest drivers and integration services for improved VM management and performance.
View definitionVMX
A .vmx file describes a VMware VM’s configuration, including virtual hardware, disk references, networking and startup settings.
View definitionVoIP
VoIP (Voice over IP) is the technology of transmitting voice as packets across an IP network, including private networks and the Internet.
View definitionVolume-Level Backup
a backup that protects a logical volume or partition as the primary unit
View definitionVPN
A VPN establishes an encrypted connection between a remote device or network and a VPN gateway over an untrusted network.
View definitionVRF
VRF is a concept or mechanism used in network & routing to isolate multiple routing tables on the same equipment.
View definitionVRF Lite
VRF Lite separates routing tables on one network device to isolate traffic without requiring an MPLS core.
View definitionVRF Route Leaking
VRF route leaking deliberately shares selected routes between otherwise isolated virtual routing tables under policy control.
