On NFS datastores that do not support Hardware Acceleration, only a thin format is available. NFS datastores with Hardware Acceleration and VMFS datastores support the following disk provisioning policies. When you perform certain virtual machine management operations, such as creating a virtual disk, cloning a virtual machine to a template, or migrating a virtual machine, you can specify a provisioning policy for the virtual disk file. To About Virtual Disk Provisioning Policies: Fault Tolerance is not supported on a virtual machine configured with a VMXNET3 vNIC in vSphere 4.0, but is fully supported on vSphere 4.1. The feature is supported starting with ESXi 5.0 for VMXNET 3 only. In ESX/ESXi 4.1 and earlier releases, Jumbo Frames are not supported in the Solaris Guest OS for VMXNET 2 and VMXNET 3. For Linux guests e1000e is not available from the UI (e1000, flexible vmxnet, enhanced vmxnet, and vmxnet3 is available for Linux). ![]() It is the default vNIC for Windows 8 and newer (Windows) guest OSes. e1000e is available only on hardware version 8 (and newer) VMs in vSphere5. Note: E1000 does not support jumbo frames prior to ESX/ESXi 4.1.Į1000e - This feature emulates a newer model of Intel gigabit NIC (number 82574) in the virtual hardware. Typically Linux versions 2.4.19 and later, Windows XP Professional 圆4 Edition and later, and Windows Server 2003 (32-bit) and later include the E1000 driver. A driver for this NIC is not included with all guest operating systems. Vmxnet2 (Enhanced vmxnet) – vmxnet adapter with enhanced performanceĮ1000 - an emulated version of the Intel 82545EM Gigabit Ethernet NIC. High-performance adapter available for only some guest operating systems vmxnet, vmxnet2, and vmxnet3 are VMware® drivers and are only available with VMware Tools Vmxnet – Provides significantly better performance than valance e1000 – e1000e Vlance – Also called PCNet32, supported by most 32-bit guest operating systems Network adapters that might be available for your virtual machine:įlexible – Can function as either a vlance or vmxnet adapter: For instance, if you need to create a virtual machine that has a hardware compatibility setting that is different from the default hardware compatibility setting, or select the I/O controller type for the SCSI controller, or select the virtual disk type, or error configure a physical disk, or allocate all virtual disk space rather than let disk space gradually increase. With the Custom Configuration option, you create a virtual machine with more advanced options. The difference between creating a Virtual Machine Typical and Custom is With the Typical Configuration option in the New Virtual Machine wizard, you create a virtual machine in a minimum number of steps. In the configuration tab, you will find options Typical, Custom. Hardware independence: Virtual machines run independently of the underlying hardware Encapsulation: Virtual machines encapsulate a complete computing environment Isolation: Virtual machines are isolated from each other as if physically separated ![]() ![]() Compatibility: Virtual machines are compatible with all standards of x86 computers In general, VMware virtual machines possess four key characteristics that benefit the user: The host that the virtual machine runs on and the guest operating system must support devices that you add or configurations that you make.Ī Virtual Machine is a logical Container with a set of discrete files. Not all hardware devices are available to every virtual machine. Desired to gain proficiency on VMware? Explore the blog post on" VMware Training "Online to become a pro in VMware. With VMware Tools, you have more control over the virtual machine interface. VMware Tools is a suite of utilities that enhances the performance of the virtual machine's guest operating system and improves the management of the virtual machine. You must have a CD/DVD-ROM or ISO image containing the installation files from an operating system vendor. You install a guest operating system on a virtual machine the same way as you install an operating system on a physical computer. Virtual machines typically have an operating system, VMware Tools, and virtual resources and hardware that you manage in much the same way as you would manage a physical computer. Virtual machines can run on an isolated ESXi host or on ESXi hosts that vCenter Server manages. A virtual machine is a software computer that, like a physical computer, runs an operating system and its applications.
