Compatibility and InstallationESXi, vCenter Server, and vSphere Web Client Version CompatibilityThe VMware Product Interoperability Matrix provides details about the compatibility of current and previous versions of VMware vSphere components, including ESXi, VMware vCenter Server, the vSphere Web Client, and optional VMware products. In addition, check this site for information about supported management and backup agents before installing ESXi or vCenter Server. The vSphere Client and the vSphere Web Client are packaged with the vCenter Server and modules ZIP file. You can install one or both clients from the VMware vCenter™ Installer wizard. Hardware Compatibility for ESXiTo determine which processors, storage devices, SAN arrays, and I/O devices are compatible with vSphere 5.1, use the ESXi 5.1 information in the VMware Compatibility Guide. The list of supported processors is expanded for this release. To determine which processors are compatible with this release, use the VMware Compatibility Guide. Guest Operating System Compatibility for ESXiTo determine which guest operating systems are compatible with vSphere 5.1, use the ESXi 5.1 information in the VMware Compatibility Guide. Beginning with vSphere 5.1, support level changes for older guest operating systems have been introduced. For descriptions of each support level, see Knowledge Base article 2015161. The VMware Compatibility Guide provides detailed support information for all operating system releases and VMware product releases. The following guest operating system releases that are no longer supported by their respective operating system vendors are deprecated. Future vSphere releases will not support these guest operating systems, although vSphere 5.1 does support them.
Virtual Machine Compatibility for ESXiVirtual machines that are compatible with ESX 3.x and later (hardware version 4) are supported with ESXi 5.1. Virtual machines that are compatible with ESX 2.x and later (hardware version 3) are no longer supported. To use such virtual machines on ESXi 5.1, upgrade the virtual machine compatibility. See the vSphere Upgrade documentation. vSphere Client Connections to Linked Mode Environments with vCenter Server 5.xvCenter Server 5.1 can exist in Linked Mode only with other instances of vCenter Server 5.1. Installation Notes for This ReleaseRead the vSphere Installation and Setup documentation for step-by-step guidance on installing and configuring ESXi and vCenter Server. Although the installations are straightforward, several subsequent configuration steps are essential. In particular, read the following:
Migrating Third-Party SolutionsYou cannot directly migrate third-party solutions installed on an ESX or ESXi host as part of a host upgrade. Architectural changes between ESXi 5.0 and ESXi 5.1 result in the loss of third-party components and possible system instability. To accomplish such migrations, you can create a custom ISO file with Image Builder. For information about upgrading with third-party customizations, see the vSphere Upgrade documentation. For information about using Image Builder to make a custom ISO, see the vSphere Installation and Setup documentation. Upgrades and Installations Disallowed for Unsupported CPUsvSphere 5.1 supports only CPUs with LAHF and SAHF CPU instruction sets. During an installation or upgrade, the installer checks the compatibility of the host CPU with vSphere 5.1. If your host hardware is not compatible, a purple screen appears with an incompatibility information message, and you cannot install or upgrade to vSphere 5.1. Upgrades for This ReleaseFor instructions about upgrading vCenter Server and ESX/ESXi hosts, see the vSphere Upgrade documentation. Test Releases of vSphere 5.1 Upgrades from the vSphere 5.1 Beta and the vSphere 5.0 Release Candidate releases to vSphere 5.1 are not supported. Uninstall ESXi 5.1 Beta or Release Candidate and vCenter Server 5.1 Beta or Release Candidate, and perform fresh installations of vCenter Server 5.1 and ESXi 5.1. If you were testing Beta or Release Candidate versions of vSphere 5.1, VMware recommends that you recreate data that you want to preserve from those setups on vSphere 5.1. vCenter Server Upgrades vSphere 5.1 supports the following upgrade scenarios.
