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.

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. After moving the virtual machine files, the new size of its virtual disk will be displayed in its properties.IA-32 (x86-32) (discontinued in 4.0 onwards), x86-64, ARM

Then just clone or migrate (using Storage vMotion) the virtual machine to another datastore.

Press ESC to exit the edit mode and then type :wq -> Enter to save the changes

Specify the new size of the virtual disk.

Using the down arrow key, go to the line containing the disk size and press i (to edit it).

Set a new size of your virtual disk using a text editor (vi or nano) It means that I have to specify 83886080 ( 40 GB*1024*1024*1024 / 512) in the Extent description section.

I want to reduce my VMDK disk from 80 to 40 GB.

The size of the vmdk disk is shown in the #Extent description section (after the RW characters).

Display the contents of the virtual disk configuration file (*.vmdk) using the cat command:.

Go the directory the VMDK file of your VM is located in (you can get a path to it in the virtual disk properties of the vSphere client):.

Using SSH, connect to the console of the ESXi host the VM is registered on (you can use putty or the built-in Windows SSH client).

Shut down the virtual machine you want to reduce disk size.

Then reduce the size of the VMDK file on the VMWare VMFS file system. Reduce the VMDK File Size of the VMWare Virtual Machine If LVM logical volumes are used, the scenario is different. In Linux, you can reduce the partition size using parted. If you don’t do it, after then your file system may crash after shrinking the virtual disk size. If your virtual machine is running Windows OS, use the Disk Manager diskmgmt.msc (the Shrink Volume operation is available in all supported Windows versions sdelete tool is used in older Windows versions to reduce the partition size) or third-party tools (like Acronis Disk Director).

How to Shrink the Partition Size in the Guest OS?įirst of all, reduce the size of the disk partition in the guest operating system.

Reduce the size of the VMDK file of the VMWare virtual machine on the VMFS (NFS) datastore.

Shrink the partition inside the guest OS.

The procedure of reducing a virtual disk size consists of two steps: Use these commands:Ĭp vmname-flat.vmdk backup_vmname-flat.vmdk

#Reduce vm esxi 6.5 drive size full#

Create a full backup of the virtual machine, or create a copy of the vmdk and flat files you want to shrink.

Delete all snapshots of the virtual machine (otherwise, you may damage the virtual disk).

Prior to reducing the size of a virtual disk, do the following on your VMWare ESXi host: However, I used this method dozens of times. This guide is not an officially supported solution on how to reduce the size of vmdk disks in VMWare.
