Changing the default HTTP(s) Reverse Proxy Ports on ESXi 8.0

by // 2 Comments

The process of changing the default ports for the ESXi Reverse Proxy service has always been pretty straight forward, which I had also shared back in 2015 HERE. While most customers stick with the default configuration (80 for HTTP and 443 for HTTPS), we do have some customers that need to change these ports to meet certain organization security and/or compliance requirements.

I recently came across a customer report where the previous method for changing the ESXi Reverse Proxy ports on an 8.0 host no longer worked and the only thing that was shared was that the user could no longer run ESXCLI directly within the ESXi Shell, which I thought was a strange observation.

I deployed the latest ESXi 8.0b as a Nested ESXi VM and I went through the instructions I had outlined in my blog post HERE and changed the HTTPS port from 443 to 4444, which was the setup the user was looking to do and I ran into the exact same issue. At first, I thought maybe we actually no longer support this capability and decided to quickly test by using the remote version of ESXCLI, which allows you to specify a port as part of the connection and it failed with the same error.

Quick Tip - How to download ESXi ISO image for all releases including patch updates?

by // 4 Comments

Not all ESXi releases, including patch updates are available as an ISO image that can be downloaded. Depending on the type of ESXi release, it will either be available as an ISO and Offline Bundle (zip) format which can downloaded from the ESXi Customer Connect portal or only as an Offline Bundle which must be downloaded from the VMware Patch portal.

I typically see folks forgetting about the VMware Patch portal, which also provides patch updates for the vCenter Server Appliance (VCSA), when they are searching for a new ESXi updates. Let's take a look at an example using the ESXi 7.0 Update 3 release, as you can see from the screenshot below, you can download 7.0 Update 3c, d, f and g from the Customer Connector portal but for 7.0 Update 3e, i, j and k you will need to use the VMware Patch portal.


As mentioned earlier, when downloading ESXi patches from the VMware Patch portal, they are only available in the Offline Bundle format, which might work for most typical patch use cases but in some scenarios, you may actually want it in an ISO format, especially for initial installation.

Is my vSphere Cluster managed by vSphere Lifecycle Manager (vLCM) as a Desired Image or Baseline?

by // 8 Comments

Prior to vSphere 7.0, ESXi lifecycle management has been provided by vSphere Update Manager (VUM), which has been around for more than a decade plus and is most likely what you are still using today. With the release of vSphere 7.0, VMware introduced a brand new lifecycle management solution for ESXi called vSphere Lifecycle Manager (vLCM), which you can read more about HERE.


While VMware has made it clear that vLCM will be the future going forward for ESXi lifecycle management, we also understand that most customers will still be using the existing VUM-based solution and we wanted to make sure it was easy to  transition between the two solutions, especially within the vSphere UI.

An interesting question was recently brought up was how to determine whether a vSphere Cluster was using the new vLCM solution based on desired images versus VUM, which uses baselines?

Note: If you are not familiar between vLCM Desired Image and VUM Baselines, be sure to check out this helpful resource HERE.
