Taking Server Virtualization Down from the Clouds to Real Life Experience: Overcoming ESXi 6.5 Load Net-Tulip Issues

As a seasoned IT professional, I have had the opportunity to work with various server virtualization technologies, including VMware’s ESXi. Recently, I encountered an issue while trying to load net-tulip drivers on ESXi 6.5, which led me down a path of discovery and experimentation. In this blog post, I will share my experience and the solutions I found to overcome these issues.

Introduction

Server virtualization is a rapidly evolving technology that has revolutionized the way we manage and deploy servers in data centers. VMware’s ESXi is one of the most popular server virtualization platforms, known for its reliability, scalability, and ease of use. However, with every new release, there are new features and improvements that can sometimes break existing functionality. This is exactly what happened when I tried to load net-tulip drivers on ESXi 6.5.

The Issue

———–

When I tried to load the net-tulip drivers using the customize 6.5 ISO, I encountered an error message stating that the driver was incompatible with ESXi 6.5. The vmkernel.log showed an Elf : 2219: Load of failed : missing required namespace error message. This was puzzling, as I had no issues loading the drivers on previous versions of ESXi.

After some research and experimentation, I found that the issue was caused by the fact that the net-tulip driver was compiled using the source code of ESXi 5.0, which is not compatible with ESXi 6.5. This led me to explore other options for resolving the issue.

Solution 1: Use a Different ISO Image

One possible solution is to use a different ISO image that includes the net-tulip driver. ESXi 6.5 Customizer PS-v2.5.ps1 can be used to add the net-tulip driver to the customize 6.5 ISO. This script will download the necessary files and create a customized ISO that includes the net-tulip driver.

Solution 2: Use PowerCLI to Resize the Window

Another solution is to use PowerCLI to resize the window. When running the script under PowerShell ISE, it always generates meaningless error messages when it tries to resize the window. To fix this issue, you can add a check to ensure that the new size is valid before resizing the window.

Solution 3: Use a Customized Version of the Vendor Image

You can also use a customized version of the vendor image that includes the net-tulip driver. This can be done by using a different ISO image that contains the net-tulip driver, or by adding the driver to the existing ISO image using PowerCLI.

Conclusion

———-

In conclusion, loading net-tulip drivers on ESXi 6.5 can be a challenging task due to compatibility issues. However, there are several solutions that can help you overcome these issues. These include using a different ISO image, using PowerCLI to resize the window, or using a customized version of the vendor image. By exploring these options, I was able to successfully load the net-tulip drivers on ESXi 6.5 and overcome the issues that I encountered.
