Incorrect guestOS type for Nested ESXi causes vCLS issues with VMware Cloud Foundation (VCF) Holodeck Toolkit

by // Leave a Comment

Several months back, I started noticing an increase number of folks reporting problems powering on their vSphere Cluster Services (vCLS) VM when using the VMware Cloud Foundation (VCF) Holodeck Toolkit solution and the following workaround can be applied, which came directly from the Holodeck developers.

While a workaround exists including vCLS script located at C:\VLC\VLC-Holo-Site-1\vclsfix, it was very puzzling because this seems to only happen with the Nested ESXi VMs and the VCF Holodeck Toolkit and it was NOT observed when deploying a regular Nested ESXi environment, but I never took a closer look to see why that might be.

A few weeks back, I recieved an email from Mike Foley (former vSphere HA and vCLS PM), I came to learn the reason folks using the VCF Holodeck Toolkit was seeing this problem and it was specific to that solution due to how the guestOS was configured for the Nested ESXi VMs.

Using Nested ESXi for VMware Cloud Foundation (VCF) Workload Domain fails with vSAN ESA Auto Disk Claim 

by // Leave a Comment

As of VMware Cloud Foundation 5.1.0, you can now use the new vSAN Express Storage Architecture (ESA) when deploying a VCF Workload Domain where as in earlier releases, only the vSAN Original Storage Architecture (OSA) was supported, which is typically what I deploy for testing purposes.

While working on some enhancements to my VCF Automated Lab Deployment Script, I needed to go through a VCF Workload Domain deployment using vSAN ESA but I kept running into the following error within SDDC Manager: Perform vSAN ESA Auto Disk Claim


Based on the error message, I had assumed there was an issue with claiming the SSD on the Nested ESXi VM for vSAN ESA but when I logged into the VCF Workload Domain vCenter Server, I was able to claim the devices without any issues. Looking at the SDDC Manager logs /var/log/vmware/vcf/domainmanager/domainmanager.log also did not yield anything useful:

After a bit of digging, I was wondering if this was related to a similiar issue that is seen during the VCF Bringup of the VCF Management Domain using vSAN ESA where a custom vSAN HCL JSON was required?

Customizing SMBIOS strings (hardware manufacturer and vendor) for Nested ESXi 

by // 10 Comments

Nested ESXi continues to be an invaluable resource that I use on almost a daily basis from solution prototyping, customer reproduction to automated lab deployments supporting both VMware Cloud Foundation (VCF) and VMware vSphere Foundation (VVF), the use cases are simply endless!

While you can do almost anything with Nested ESXi, mimicking or simulating specific hardware strings such as the manufacturer or vendor is not really possible or at least very easily. I was recently reminded of this topic again as this has been something I wanted to look into but just not had the time. In fact, some of this was inspired by a conversation I had with fellow colleague Luke Huckaba who found a clever trick playing with the default Virtual Machine boot ROMs which are shipped with both ESXi and our VMware Desktop Hypervisors (Workstation/Fusion).
