New editions then followed: ESXi 3.5, ESXi 4, ESXi 5 and (as of 2015 ) ESXi 6.
Originally named VMware ESX Server ESXi edition, through several revisions the ESXi product finally became VMware ESXi 3.
Esxi versions upgrade#
One can upgrade ESXi to VMware Infrastructure 3 or to VMware vSphere 4.0 ESXi.
Esxi versions install#
The same media can be used to install either of these variations depending on the size of the target media. With a simple configuration console for mostly network configuration and remote based VMware Infrastructure Client Interface, this allows for more resources to be dedicated to the guest environments. VMware ESXi originated as a compact version of VMware ESX that allowed for a smaller 32 MB disk footprint on the host.
Esxi versions license#
It is available - without the need to purchase a vCenter license - as a free download from VMware, with some features disabled. VMware ESXi, a smaller-footprint version of ESX, does not include the ESX Service Console. These Microsoft operating systems can only run on ESXi 5.x or later. VMware ESX is available in two main types: ESX and ESXi, although since version 5 only ESXi is continued.ĮSX and ESXi before version 5.0 do not support Windows 8/Windows 2012. This information, together with the error codes displayed on the purple diagnostic screen can be used by VMware support to determine the cause of the problem. Upon displaying a purple diagnostic screen, the vmkernel writes debug information to the core dump partition. This is colloquially known as a purple diagnostic screen, or purple screen of death (PSoD, cf. This results in an error message displayed on a purple diagnostic screen. In the event of a hardware error, the vmkernel can catch a Machine Check Exception. The Service Console, for all intents and purposes, is the operating system used to interact with VMware ESX and the virtual machines that run on the server.Ī purple diagnostic screen from VMware ESXi 4.1 Both of these Console Operating System functions are being deprecated from version 5.0, as VMware migrates exclusively to the ESXi model. In ESX (and not ESXi), the Service Console is a vestigial general purpose operating system most significantly used as bootstrap for the VMware kernel, vmkernel, and secondarily used as a management interface. has changed the module-loading and some other minor things. Programmers have adapted them to run with the vmkernel: VMware Inc.
Esxi versions drivers#
These drivers mostly equate to those described in VMware's hardware compatibility list. According to the README file, "This module contains the Linux emulation layer used by the vmkernel." To access these modules, an additional module called vmklinux implements the Linux module interface. At least some of the modules derive from modules used in the Linux kernel. Īccess to other hardware (such as network or storage devices) takes place using modules.
The vmkernel handles CPU and memory directly, using scan-before-execution (SBE) to handle special or privileged CPU instructions Īnd the SRAT (system resource allocation table) to track allocated memory. The vmkernel is a microkernel with three interfaces: hardware, guest systems, and the service console (Console OS). VMware dropped development of ESX at version 4.1, and now uses ESXi, which does not include a Linux kernel at all. At normal run-time, the vmkernel was running on the bare computer, and the Linux-based service console ran as the first virtual machine. The Linux kernel was the primary virtual machine it was invoked by the service console. In the historic VMware ESX, a Linux kernel was started first and then used to load a variety of specialized virtualization components, including ESX, which is otherwise known as the vmkernel component. ĮSX runs on bare metal (without running an operating system) unlike other VMware products. In September 2004, the replacement for ESX was internally called VMvisor, but later changed to ESXi (as the "i" in ESXi stood for "integrated"). The name ESX originated as an abbreviation of Elastic Sky X.
Esxi versions software#
ESX/ESXi is the primary component in the VMware Infrastructure software suite. ESXi replaces Service Console (a rudimentary operating system) with a more closely integrated OS. Īfter version 4.1 (released in 2010), VMware renamed ESX to ESXi. As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS) instead, it includes and integrates vital OS components, such as a kernel. VMware ESXi (formerly ESX) is an enterprise-class, type-1 hypervisor developed by VMware for deploying and serving virtual computers.
