VMware ESXi 6.5 - IO Devices not certified for upgrade

vmware-hcl-65Beside Server Hardware, also double check if your IO Devices (eg. NIC, HBA,..) are supported when updating ESXi hosts from VMware vSphere 6.0 to 6.5. The following devices were supported in vSphere 6.0 but are according to VMwares HCL not (yet) supported in vSphere 6.5.

  • Not supported does not say that it does not work.
  • The list has been created with the help of my IO-Devices HCL in JSON Format.

Script to add vSphere 6.5 VMCA Root Certificate to Trusted Certs Store

When running vSphere 6.5 deployments in default (recommended) mode, VMware Certificate Authority is its own root certificate authority. Everything fine and secure with this configuration, but your browser displays a warning because the root certificate is not trusted.

I made a little script (VBS) that pulls the CA certificate from a vCenter Server or Platform Services Controller and adds it to the local trusted root certificates store. When the root CA is trusted, browser warnings are gone.

Heads Up - ESXi not working on 7th Gen (Kaby Lake) Intel NUC7

I've received reports that the ESXi 6.5 and ESXi 6.0 installer fails to load on the latest 7th Gen NUCs:

  • NUC7i3BNH
  • NUC7i3BNK
  • NUC7i5BNH
  • NUC7i5BNK

The main issue is that the I219-V NIC is not recognized, so the installer fails with the well known "No Network Adapters" error message. Today I managed to get my hands on a NUC7i3BNH to narrow down the issue. By now I've not managed to get the embedded Network Adapter to work. A workaround with a USB-based NIC is possible.

[Update 2017-02-25 - A fix is available]

This article explains how to lower the resource consumption to be able to lower the memory to about 6GB without noticable impacts.

How to add AD Authentication in vCenter 6.5

The vCenter Server has an internal user database that allows you to add and manage users with the vSphere Web Client. Users management and Single Sign-On is provided by the Platform Service Controller which is available since vSphere 6.0. In a large environment, you might want to connect your virtualization infrastructure to a centrally manage Active Directory.

This article explains how to add AD authentication in vSphere 6.5 and how to get the "Use Windows session authentication" checkbox to work with the enhanced authentication plugin. This works for both, the vCenter Server 6.5 installed on a Windows Server and the vCenter Server Appliance (vCSA).

How to Join the vCSA 6.5 to an Active Directory Domain

In vSphere 6.5 the underlying operating system from the vCenter Server Appliance (vCSA) has been changed to VMwares PhotonOS. With the new OS, you can still join an Active Directory domain to comply with company policies, or if you want to use windows session authentication. Joining an Active Directory domain is included in the infrastructure node configuration which is part of the Platform Services Controller. Please verify standard AD requirements like time synchronization and naming prior to joining a domain.

If you want to log in with the "Windows session authentication" checkbox, you have to add the appliance running the Platform Services Controller (PSC) to the domain. For embedded deployments, join the appliance running both, the vCenter and the PSC to the domain.
