VMware Cloud Foundation with a single ESXi host for Management Domain?

by // 18 Comments

By default, VMware Cloud Foundation (VCF) requires a minimum of 4 ESXi hosts to construct the Management Domain which is fine for a production environment, but it can be a challenge for those interested in explore VCF in a homelab setting.

I recently came to learn about a really cool tidbit from one of our VCF Engineers on how you can actually deploy a VCF Management Domain using just a single ESXi host, ideal for a homelab setup! ?


Not only could this benefit users in deploying a physical VCF setup but it would also benefit anyone using my Automated Lab Deployment Script for VCF, which makes it super easy by leveraging my Nested ESXi Virtual Appliance VMs.


In fact, that was how I quickly verified this trick works using my VCF automation script 😀

The way that this work is a configuration change to Cloud Builder to tell it to allow a single ESXi host to be used and it will simply setup a single node vSAN Cluster, which is typically how you would bootstrap if you were doing a greenfield deployment. The only difference here is that instead of adding additional 3 x ESXi hosts to provide redundancy for Management Domain, it simply is relaxing that requirement and thus allowing for a single ESXi host. vSAN is still a requirement for VCF Management Domain, so ensure you can meet those requirements still.

NSX Alarms in vCenter Server using vSphere Events in vSphere 8

by // Leave a Comment

I recently learned about a really cool capability that is part of the NSX Easy Install feature that was initially introduced back in vSphere 7.0 Update 3, allowing administrators to easily deploy, configure and manage NSX directly from vCenter Server using the vSphere UI.

Here is a demo of this feature in action by fellow VMware colleague Vladimir Velikov, one of the Engineers who worked on the initial integration:

While reviewing the latest NSX 4.0.1.1 release notes, which adds support for vSphere 8 and DPU-based offloading, I found this little nugget at the very end of the What's New section under NSX vSphere UI Integration which states:

NSX Events Integrated in vCenter

? whoa, the possibilities of this integration is immense, especially from an automation and event-driven standpoint ... In fact, this is something VMware Event Broker Appliance (VEBA) users have been asking for, a way to tap into the rich Alarms and Events provided by NSX, similiar to what vCenter Server provides out of the box with over 2000+ events.

Integrated NSX-T deployment in vSphere 7.0 Update 3 fails with timeout

by // 2 Comments

One of the new features highlighted in the latest vSphere 7.0 Update 3 release is the integrated NSX-T deployment and configuration workflow found directly within the vSphere UI as shown in the screenshot below.


After you click on the the "Install NSX" button, it will prompt for the NSX-T OVA and then take users through a guided wizard to on deploying and configuring NSX-T. I noticed that a few users were reporting a timeout issue after running through the workflow:

Cannot complete the operation: See the event log for details. Timeout: The task did not complete within the expected time span

I have not used this plugin before, so I was not sure what the issue was until I came across this Tweet from Validimir Velikov, a vSphere UI Engineer who had worked on the integrated NSX-T plugin and shared the reason for this error. A newer version of NSX-T will be needed to use this feature as the vSphere UI expects a "callback" from NSX-T Manager when the deployment and configuration is complete, which the current released version of NSX-T (3.1.3.1) does not support.

I think we could have provided a better user experience by first checking the NSX-T OVA version and ensuring that it meets the minimum version that supports this capability. Hopefully this is something we can improve upon in the future.
