Easily create custom ESXi Images from patch releases using vSphere Image Builder UI

by // 11 Comments

Creating a custom ESXi Image Profile that incorporates additional ESXi drivers such as the recently released Community Networking Driver for ESXi Fling or Community NVMe Driver for ESXi Fling is a pretty common workflow. Due to the infrequency of this activity, many new and existing users sometime struggle with the process to quickly construct a new custom ESXi Image Profile. I personally prefer to use the Image Builder UI that is built right into the vSphere UI as part of vCenter Server.

There are a couple of ways to create a custom new ESXi Image Profile using the Image Builder UI, but the easiest method is to use the Clone workflow, which is especially helpful when you are selecting an ESXi patch release as your base image.

With a regular major release, you only have to deal with two image profiles: standard (includes VMware Tools) and no-tools (does not include VMware Tools).

With an ESXi patch release, you actually have four image profiles: standard (includes VMware Tools + all bug/security fixes), security standard (includes VMware Tools + security fixes only), security no-tools (does not include VMware Tools + security fixes only) and no-tools (does not include VMware Tools + all bug fixes)

If you start with an empty custom image profile and then select your ESXi base image, you will notice there are multiple VIB version packages to select from since patch release you had imported earlier actually contains four different ESXi image profiles. Below are a step by step instructions on using the cloning workflow since this is a question I get from users who run into package conflicts not realizing they have selected the same package multiple times.

Deploying NSX-T VIBs and/or creating custom NSX-T Image Profile

by // Leave a Comment

Similiar to its earlier predecessor, NSX-T also provides complete lifecycle management (LCM) of its underlying NSX components (Controllers, Edges and Managers) including the Fabric Nodes (e.g. ESXi and/or KVM hosts). Additionally, a new Upgrade Coordinator is now part of NSX-T which greatly simplifies the patching and updating of the network virtualization platform. However, for existing vSphere customers who already have a process for distributing VMware VIBs using vSphere Update Manager (VUM) and/or custom Image Profiles, being able to leverage their existing methods is quite important. This is especially true for customers or system integrators who wish to slipstream all necessary VIBs as part of their base ESXi image for initial deployment which may come in the form of an automated installation via Kickstart and/or even manual install using an ISO image.

The good news is that like NSX-V, NSX-T also supports the same set of deployment methods that customers are already familiar with. I had recently looked into this due to a few questions that I and a few other folks had during our NSX-T Bootcamp training a couple of weeks back. I also did not see anything in the existing NSX-T documentation and figure it would be useful to outline the specific steps for each of the installation methods, especially when creating a custom ESXi Image Profile using PowerCLI which requires a particular order.

Note: Auto Deploy is currently not supported with NSX-T.

Quick Tip - Listing Image Profiles From an ESXi Patch Using ESXCLI

by // 6 Comments

I was cleaning out a few of my to-do items (list just keeps getting longer everyday) this morning and there was a question that I received a few weeks back asking how to retrieve the list of Image Profiles for a given ESXi patch. This is actually quite easy and you will want to use ESXCLI.

Note: The examples shown below is using ESXCLI on the ESXi Shell, but these commands can be execute remotely as well using ESXCLI or through PowerCLI with Get-EsxCli cmdlet.

To list the available Image Profiles for an ESXi patch, run the following command (ensure you substitute the full path to your ESXi patch):

esxcli software sources profile list -d /vmfs/volumes/datastore1/ESXi510-201212001.zip

To get more details on a particular Image Profile, run the following command and specify the -p for the specific Image Profile:

esxcli software sources profile get -d /vmfs/volumes/datastore1/ESXi510-201212001.zip -p ESXi-5.1.0-20121204001-no-tools

To install/update a specific Image Profile, run the following command with the Image Profile name:

esxcli software profile update -d /vmfs/volumes/datastore1/ESXi510-201212001.zip -p ESXi-5.1.0-20121204001-no-tools

If you just want to install the ESXi patch, run the following command which will install the esx-base Image Profile by default which will include everything:

esxcli software vib update -d /vmfs/volumes/datastore1/ESXi510-201212001.zip

To check for the Image Profile you have installed on your ESXi host, run the following command:

esxcli software profile get
