Quick Tip - Retrieving ESXi Host Fingerprint for VCF Installer JSON deployment

by // Leave a Comment

When deploying a new VMware Cloud Foundation (VCF) 9.0 Fleet, the VCF Installer will automatically retrieve the fingerprint for each of the ESXi hosts that you have added and have you confirm that they actually match your ESXi hosts.


For automated VCF deployments, you can provide a JSON manifest that fully describes your VCF 9.0 deployment and by default, the VCF Installer will expect the ESXi fingerprints to be included or validation will fail.

So what are these fingerprint values and how do you retrieve them like the VCF Installer?

MS-A2 VCF 9.0 Lab: Installing VMware Private AI Services (PAIS)

by // Leave a Comment

Over the past couple of months, I have used my minimal VMware Cloud Foundation (VCF) 9.0 lab to explore nearly every major VCF 9.0 capability including NVMe Tiering, vSAN ESA, NSX VPC, vSphere Supervisor Services like vSphere Kubernetes Service (VKS), VM Service & ArgoCD, VCF Operations (VCFO), VCF Automation (VCFA), VMware AVI Load Balancer, Data Services Manager (DSM) and the list goes on and on! 😅

One area that I have been interested in diving deeper into is with our Private AI offerings and with the announcement of VMware Private AI Services (PAIS) now included as part of VMware Cloud Foundation (VCF), it gave me that additional motivation to see if I could also run PAIS in my lab!

As part of my exploration, I will be documenting my experience in a mini-blog series on installing and configuring PAIS to deploy an AI Agent using an NVIDIA GPU with DirectPath I/O. Since NVIDIA vGPU requires an NVIDIA AI for Enterprise (NVAIE) license, this approach can especially be useful for lab and learning purposes.

Quick Tip - Custom JSON for Deploying VMware Cloud Foundation (VCF) with Custom TLS Certificates

by // Leave a Comment

ESXi hosts deployed with a custom CA signed TLS certificate can be consumed by either VMware Cloud Foundation (VCF) 5.x Cloud Builder or 9.x VCF Installer using a custom JSON deployment manifest.

An additional securitySpec should be appended to your VCF JSON deployment manifest using the following format:

"securitySpec": {
  "esxiCertsMode": "Custom",
  "rootCaCerts": [
    {
      "alias": "custom-CA",
      "certChain": [
        "-----BEGIN CERTIFICATE-----\nMIIDqzC...\n...\n...==\n-----END CERTIFICATE-----"
      ]
    }
  ]
}
