Automating the Reporting of VCF Workload Domain Import Pre-Check Validations

12.04.2025 by William Lam // 3 Comments

After completing the VMware Cloud Foundation (VCF) Workload Domain Import workflow, I realized it would be helpful to be able to view the pre-check validations outside of the VCF Operations UI, especially if there are multiple pre-checks that have failed.


While the VCF Operations UI provides a good overview of all pre-checks, it does not provide any filtering or sorting, so you have to skim scroll through the entire list (55 in my case) to see which ones failed. For each failed validation, you can get more details including the recommended remediation, but you need to expand each section which can be painstaking if you have more than a few failures.

This is where we can leverage the power of automation and the VCF APIs ...

Import vCenter Server with Single ESX Host as new VCF Workload Domain?

12.03.2025 by William Lam // Leave a Comment

A useful feature in VCF Operations 9.0 is the ability to create a new VMware Cloud Foundation (VCF) Workload Domain from an existing vSphere environment, providing seamless onboarding into a VCF Fleet and getting access to the new VCF Fleet Management capabilities.

To access the VCF Import feature, navigate to the inventory view of your VCF Instance within VCF Operations and select Add Workload Domain->Import a vCenter Server to begin the workflow. A variety of deployment configurations are supported with VCF Import, you can refer to the official documentation for the complete list of requirement and minimum versions.

Deploying VCF 9.0 in a lab environment is an easy way to get hands on experience with this workflow. I recently installed ESX 9.0.1 onto a single ASUS NUC 15 Pro with a self managing vCenter Server for trying out the import scenario but I ran into the following pre-check error: Please ensure there is at least one cluster has more than 1 host


I guess I need to have more than one ESX host before I can proceed ... or do I? 🤔

Managing Storage for VCF Automation (VCFA) Content Library Transfer Spooling Area

12.01.2025 by William Lam // 7 Comments

When a user uploads an ISO/OVF/OVA from their desktop to VCF Automation (VCFA) Content Library, the file is temporarily stored in the Transfer Spooling Area (TSA) that resides locally within VCFA before it is finally transferred to the destination vCenter Server.


By default, VCFA uses an embedded object store backed by SeaweedFS to hold the temporary user files, which are stored in 64MB chunks. The size of the SeaweedFS volumes will be based on the VCFA deployment mode (single node vs multi-node for HA). A total of three volumes (3 replicas) will always be configured regardless of the deployment mode for VCFA and the total usable storage capacity is sum of these three volumes.

  • Single Node, each volume is 75GB
  • Multi-Node (Medium), each volume is 150GB
  • Multi-Node (Large), each volume is 200GB
