Quick Tip: Workaround for NSX Edge Upgrade to VCF 9.0.1 running AMD Ryzen CPUs

by // 5 Comments

If you are planning to upgrade to latest release of VMware Cloud Foundation (VCF) 9.0.1 and you are using an AMD Ryzen (consumer) processor, you will need to apply an additional workaround after your NSX Edges have been upgraded, for proper functionality. This is similar to the workaround that I had shared back in 2020, which is needed when deploying a new VCF 9.x environment due to the incompatibility of NSX Edges running on an AMD Ryzen CPU.

UPDATE (01/20/26) - VCF 9.0.2, the structure of the config.py has changed, you will need to identify the correct lines to comment out the AMD section. There is a more simpler workaround that can now be applied for all VCF releases, which you can find more details in this blog post HERE.

After the NSX Edge node has been upgraded, the modifications to the original system files are not persisted and we need to re-apply the changes before the NSX Edge nodes will run properly.

Thanks to Tomas Fojta for sharing this tidbit while upgrading his environment, which happens to run on an AMD Ryzen system.

Step 1 - SSH to the NSX Edge node as root

Step 2 - Edit /os_bak/opt/vmware/nsx-edge/bin/config.py and comment out L192-193 containing the AMD section and that will allow the NSX Edge to properly startup and complete the upgrade flow.

MS-A2 VCF 9.0 Lab: Configuring NSX Virtual Private Cloud (VPC)

by // 2 Comments

This post is part of a short series that builds on our minimal VMware Cloud Foundation (VCF) 9.0 deployment (2x Minisforum MS-A2) and showcases how to fully leverage the exciting new capabilities in the VCF 9 platform, all while maintaining a minimal resource footprint, which is ideal for lab and learning purposes.

In this blog post, we will walk through the configurations steps to enable NSX Virtual Private Cloud (VPC) for our VCF 9 environment and demonstrate how to consume a VPC with your workloads.


I want to give a special shoutout to Dimitri Desmidt, who works in our Technical Marketing team and has been instrumental in helping me better understand NSX VPCs and how they work!

Here are some additional NSX VPC Resources that might be of interests if you would like to learn more:

Is my NIC supported with Enhanced Data Path (EDP) with VCF 9.0

by // Leave a Comment

By default, VMware Cloud Foundation (VCF) 9.0 will use the optimized Enhanced Data Path (EDP) Standard switch mode when configuring NSX, which will require you to have an EDP capable network adaptor. One way to check whether your network adaptor supports EDP is by using the Broadcom Compatibility Guide (BCG) and ensuring "Enhanced Data Path - Interrupt mode" feature

Alternatively, if you already have ESXi running, you can quickly check by running the following command: esxcfg-nics -e
