Workaround for VMware Cloud Builder 10GbE pre-check in VMware Cloud Foundation 5.0

by // 8 Comments

VMware Cloud Foundation (VCF) 5.0 is now generally available for customers to upgrade and I had a chance to play with it in my homelab before it was released.

One change that I had noticed in the new version of the VMware Cloud Builder for VCF 5.0 compared to VCF 4.5 is the introduction of a new 10GbE pre-check to ensure that your physical ESXi hosts met the minimum networking requirement. For a production deployment, this pre-check makes a ton of sense but for a homelab/development environment where you may not have 10GbE connectivity, this is certainly not ideal, especially as this was possible with VCF 4.5.

With VCF 5.0, this new pre-check is considered an error and will prevent you from continuing the VCF deployment as you can see from the error message below.


Fortunately, I was able to find an easy workaround to the issue that would still allow users to deploy the latest VCF 5.0 without 10GbE networking! 😀

Custom vCenter Server Role using vSphere Terraform Provider on VMware Cloud on AWS

by // Leave a Comment

In a VMware Cloud on AWS (VMC-A) environment, a default CloudAdmin vCenter Server Role is provided to customers to manage and deploy workloads in vCenter Server. Typically, this vCenter Server Role is only granted to limited number of Cloud Administrators within your organization, which you get to control as an end user.

VMware also supports customers in creating additional custom vCenter Server Roles that limits the privileges for other usage such as auditing or workload provisioning. If you create a custom vCenter Server Role for VM provisioning and you are using vSphere Automation Tools that VMware supports including PowerCLI or even the popular vSphere Terraform Provider, you may come across the following error message during the VM deployment:

System.Read privilege required for config.distributedVirtualSwitch


As you can see from the error message, the current user does not have the Read-only privilege assigned to the Virtual Distributed Switch (VDS) which is required by the automation client, in this case the vSphere Terraform Provider, to be able to properly provisioned a VM.

Note: When using the default CloudAdmin role, VMware automatically applies the correct privileges to all applicable vSphere Inventory objects and this is the reason you do not see this problem when using an account with the default CloudAdmin role. For custom vCenter Server Roles that are created by customers, we can not apply this automation as the intention of the custom role(s) are unknown to VMware.

We can quickly fix this issue by following the instructions below which will guide you in properly assigning the correct vSphere permissions to enable VM provisioning when using a non-CloudAdmin role.

Will this Arm SoC work with ESXi-Arm?

by // 12 Comments

The number of Arm-based hardware kits has grown significantly in the last couple of years. Today, there are many more options to choose from including different form factors and even hardware from some of the more traditional x86 vendors, which also demonstrates the market opportunity and the demand for Arm-based workloads.

Running ESXi-Arm is definitely a great way to bring all the benefits of the VMware ESXi Hypervisor to your Arm-based workloads including leveraging the powerful vSphere platform by connecting that to an x86 vCenter Server.

As of this publishing this blog post (06/01/23), ESXi-Arm supports over a dozen different hardware platforms that spans Datacenter, Near Edge and Far Edge:

If you want to use ESXi-Arm, which is completely free, we definitely recommend looking at this list of Arm hardware kits and you can always find the latest supported Arm-based hardware under the ESXi-Arm Requirements section.

With that said, we continue to see new Arm-based kits and SoCs that are being released on a regular basis and question that I typically see get asked from our customers and field is will this work with ESXi-Arm?
