IMPORTANT: vCenter Server Appliance 6.5 builds have been removed as of November 14, 2017 due to a deployment-impacting issue. This issue does not impact Windows installed vCenter Servers. To resolve this issue, you must upgrade to vCenter Server Appliance 6.5 Update 1c or later. For more information, see KB 51124.
The VMware Product Interoperability Matrix provides details about the compatibility of current and earlier versions of VMware vSphere components, including ESXi, VMware vCenter Server and optional VMware products. Check the VMware Product Interoperability Matrix also for information about supported management and backup agents before you install ESXi or vCenter Server.
Virtual machines that are compatible with ESX 3.x and later (hardware version 4) are supported with ESXi 6.5. Virtual machines that are compatible with ESX 2.x and later (hardware version 3) are not supported. To use such virtual machines on ESXi 6.5, upgrade the virtual machine compatibility. See the vSphere Upgrade documentation.
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.
During an installation or upgrade, the installer checks the compatibility of the host CPU with vSphere 6.5. If your host hardware is not compatible, a purple screen appears with an incompatibility information message, and the vSphere 6.5 installation process stops.
Important: Upgrades or migration of vCenter Server earlier than 5.5 Update 3b when the environment is with an external vCenter Single Sign-On to vCenter Server 6.5 Update 1 with an external Platform Services Controller are unsupported. For example, to upgrade or migrate vCenter Server 5.5 with an external vCenter Single Sign-On to vCenter Server 6.5 Update 1 with an external Platform Services Controller, you must first update to vCenter Server 5.5 Update 3b and then perform the upgrade or migration to vCenter Server 6.5 Update 1.
The copyright statements and licenses applicable to the open source software components distributed in vSphere 6.5 are available at You need to log in to your My VMware account. Then, from the Downloads menu, select vSphere. On the Open Source tab, you can also download the source files for any GPL, LGPL, or other similar licenses that require the source code or modifications to source code to be made available for the most recent available release of vSphere.
The vSphere Client is written in an HTML5-based language and frameworks supported by all browsers. However, different browsers have different performance characteristics regarding the HTML5 standard. In particular, performance with Internet Explorer 11 can be slower than with other browsers, because of the rendering engine that Internet Explorer 11 uses. If you experience such issues, try using another supported browser.
The VMware Lifecycle Product Matrix provides detailed information about all supported and unsupported products. Check the VMware Lifecycle Product Matrix also for further information about the End of General Support, End of Technical Guidance, and End Of Availability.
VMware is announcing discontinuation of its third party virtual switch (vSwitch) program, and plans to deprecate the VMware vSphere APIs used by third party switches in the release following vSphere 6.5 Update 1. Subsequent vSphere versions will have the third party vSwitch APIs completely removed and third party vSwitches will no longer work. For more information, see FAQ: Discontinuation of third party vSwitch program (2149722).
As of vSphere 6.5, VMware is discontinuing the installable desktop vSphere Client, one of the clients provided in vSphere 6.0 and earlier. vSphere 6.5 does not support this client and it is not included in the product download. vSphere 6.5 introduces the new HTML5-based vSphere Client, which ships with vCenter Server alongside the vSphere Web Client. Not all functionality in the vSphere Web Client has been implemented for the vSphere Client in the vSphere 6.5 release. For an up-to-date list of unsupported functionality, see Functionality Updates for the vSphere Client Guide.
Cross vCenter Server provisioning, which was introduced in vSphere 6.0, is not supported across all vCenter Server versions. The cross-vCenter provisioning operations not supported across different versions of vCenter Server include vMotion, cold migration, and cloning. For more information on the supported matrix for cross-vCenter operations with different update versions, see
VMware vCenter Operations Foundation 5.8.x is no longer offered, interoperable or supported with the release of vSphere 6.5. If you want to continue using vCenter Operations Foundation 5.8.x products, you can do so only with vSphere 5.5 and vSphere 6.0.
vSphere 6.5 is the final release that supports binary translation mode virtualization of operating systems. Future vSphere releases will not include binary translation mode. For more information, see
You cannot create new legacy (Record & Replay / uni-processor) Fault Tolerance virtual machines on vCenter Server 6.5 and ESXi 6.5 hosts. If you want to continue running legacy Fault Tolerance virtual machines, remain with ESXi 6.0 or earlier. Existing legacy Fault Tolerance virtual machines continue to be supported on ESXi hosts earlier than 6.5 and managed by vCenter Server 6.5.
If you wish to upgrade ESXi hosts to 6.5, turn off legacy Fault Tolerance (do not only disable Fault Tolerance) on the protected VMs prior to upgrading. SMP-FT (multiprocessor Fault Tolerance) is not automatically enabled on the VM. You must manually turn on Fault Tolerance (which becomes SMP-FT) for VMs on the newly upgraded 6.5 ESXi host.
While you take a file-based backup, and don't want to send or receive data over the default system proxy of the vCenter Server Appliance, you can list the backup servers on NO_PROXY list so that you can directly upload the backup data to those servers. When you try to perform the file-based backup, the operation fails, because NO_PROXY setup at /etc/sysconfig/proxy is ignored.
During guest customization, vCenter Server uses the vmtoolsd command to send the customization status to the host. However, when you attempt to apply guest customization to a Linux OS, the customization code cannot locate the vmtoolsd location. As a result, the customization process fails and the requested changes are not applied to the guest.
Starting with Windows Vista and Windows Server 2008, Microsoft deprecated SHFileOperation. As a result, guest customization for different Windows operating systems fails intermittently. The log file gives the following information:
Moving SysprepDir from sysprep to C: failed.Err:2.
In VMware vCenter Server 6.5, the VMware Component Manager has a different logger configuration than before. When you perform an in-place upgrade from vCenter Server 6.0 to vCenter Server 6.5, the new logger configuration does not overwrite the old one.
Deployment sizes during migration or upgrade to vCenter Server Appliance 6.5 are not available in the information table and for selection if the disk size of any vCenter Server Appliance partition is greater than the threshold for that deployment size.
This issue is resolved in this release. The file vcsa-cli-installer-metadata.json provides metadata information about the process, and the file vcsa-cli-installer-status.json provides detailed information about the process.
This issue is resolved in this release. If the root password of the vCenter Server Appliance is expired, you see the following message:
Appliance (OS) root password expired.
The message does not appear if SSH is disabled on a source vCenter Server Appliance.
When you upgrade vCenter Server Appliance that resides on an ESXi host with the free Hypervisor license, the upgrade fails with an internal error. This issue occurs because the ESXi host needs a different license. However, the error message does not specify what causes the problem and what is the resolution of the issue.
vCenter Server Appliance upgrade from version 5.5 to version 6.5 might fail while running the update-boot scripts of vpxd. This happens when vCenter Server Appliance 5.5 has a DPM-enabled cluster where vpxd tries to re-encrypt the DPM related VCDB content with a new SSL key.
vSphere 6.5 allows only unique names across all Distributed Virtual Switches and Distributed Virtual Portgroups in the same network folder. Earlier releases of vSphere allowed a Distributed Virtual Switch and a Distributed Virtual Portgroup to have the same name. When upgrading the vSphere environment from a version that allows duplicate names, the vCenter Server Appliance pre-upgrade check fails with the following error:
The temporary log file autodeploy-service.log might grow to a quite large size over time. Even if you delete the file, restarting the Auto Deploy service creates the temporary file and increases the size indefinitely without rotation.
This issue is resolved for upgrades of vCenter Server on a Windows VM when an embedded Microsoft SQL Express database is present. The outdated SQL Native Client does not trigger errors and is later replaced by the PostgreSQL ODBC driver.
The internal vCenter HA user password in the vCenter Server Appliance expires automatically after 60 days of deployment, causing the vCenter HA cluster to enter a degraded state. The vCenter HA user account is used for communication between the vCenter HA cluster nodes and because of the password expiration, the replication between the Active and Passive nodes cannot be performed. The vCenter HA cluster continues to heartbeat, but the actual replication is stopped.
VM Snapshot Size (GB) alarm is reset if the virtual machine is shut down. Alarm fails to trigger after the VM is powered on. This issue occurs in alarms based on VM Snapshot (GB) and Vm Total Size on Disk because their status is altered when the power state of the VM is changed. This issue occurs because disk usage of a VM is the same regardless of the VM power state.
