Building a Nested ESXi Lab for VMware Cloud Foundation (VCF) (updated 2023-Dec)

Introduction

The following post is very long and will contain updates as the technology changes and I figure out better ways to accomplish these tasks. VMware Cloud Foundation, or VCF, requires at least four nodes for the Management Domain. Unfortunately, I do not have hundreds of thousands of dollars for physical hardware to test and learn VCF.

Since this is a nested lab, there are a few things that will need to be set up to make this work. These items, in particular networking, have to be configured in a way to allow the nested virtual machines to communicate. This is not applicable in production where the physical hosts are cabled into Top of Rack switches.

Ubuntu 18.04 Automatic Zime Zone

While traveling outside of my home time zone, I opened my computer and found that the time was incorrect. This was to be expected because I had yet to connect to the Internet. So naturally, I connected the Wi-Fi, and checked the date and time to see that nothing happened. Hmm, OK.

I restarted my computer thinking it will restart the ntp client, still no luck, so now Google time. Looks like a little utility called ‘gnome-clocks’ might be able to give me multiple clocks which is also something I was looking for. Once installed, I had to reboot again. Sure this is a neat utility, but it still didn’t update the clock and timezone on my computer.

On this reboot, however, I noticed a little location symbol near the system menu and it dawned on me. Of course my computer would need to have location services in order to figure out where I am. Now I just wonder why when setting the ‘Automatic Zime Zone’ toggle, that I am not prompted or warned that I must also have location services turned on.

Afterthought — Read the Fucking Manual (RTFM)

Yes, that’s right, the Ubuntu Desktop Guide literally spelled out what I needed to do and it was there the whole time.
