With the release of vSphere 8, some of you may need a solution for creating a bootable USB installer for ESXi 8 on macOS without using a 3rd party utility. You will be happy to know that my previous blog post Create a Bootable ESXi 7 USB Installer on macOS, still works perfectly. Note this…
If you are hitting this error while trying to launch the VCSA Installer, “Installer” is damaged and can’t be opened. You should eject the disk image. This is most likely just macOS Security Gatekeeper getting in the way, don’t worry the fix is simple! Note: This issue also affects the CLI Installer too. To have…
Just a quick post on changing the system storage media size for ESXi 7.0 Installation. As of ESXi 7.0, a new partition layout was introduced and the installation can now consume up to 138GB of storage to allow for new features and enhancments to be added in future releases.

Customising ESXi image profiles is helpful when you need to add custom drivers to your ESXi installation image. I will demonstrate in this post, how to customise ESXi image profiles using the built-in Image Builder service on vCenter 7. I usually use Powershell to build customised ESXi images; however, non-windows users might find this handy…
I get this issue quite a bit in my homelab, and it’s expected as I frequently rebuild hosts, replace SSL certificates etc. The reason it happens is that the key to the IP address you’re connecting to is saved in the file, “known_hosts” from a previous session, and is now different to the one you…
In this post, I’ll explain how easy and non-distrustfully it is to convert Thick disks to Thin on vSAN. Firstly you should understand that objects on vSAN are all thinly provisioned by default and there is no real concept of Thick disks. Instead, vSAN has the concept of Space Reservation, defined by the Storage-Policy ruleset Object…

Last year I posted a guide on creating a ESXi 6.7 USB Installer on macOS without any 3rd party tools. This is an updated guide using ESXi 7.0b. I’ve included a short video demonstration. Note, this guide is based on macOS only, if you are using Windows please use the Rufus utility. Prerequisites Download the…
Last year I wrote the follow guide Install Free Let’s Encrypt SSL Certificate for your vCenter 6.7 Lab. The certificate was issued by Let’s Encrypt via a project called ZeroSSL. Recently ZeroSSL stopped using Let’s Encrypt, and started issuing the certificates themselves, therefore the process to generate the certificate outlined in that guide is no…
I faced this error on Chrome. You cannot visit “site” right now because the website uses HSTS. The HTTP Strict-Transport-Security response header (HSTS) lets a web site tell browsers that it should only be accessed using HTTPS, instead of using HTTP, therefore, preventing access. I received this error because I had accessed this URL previously…
