Virtual ethernet card Network adapter 1 is not supported – ESXi 7.0.3

By | February 10, 2023

“Virtual ethernet card ‘Network adapter 1’ is not supported. This is not a limitation of the host in general, but of the virtual machine’s configured guest OS on the selected host”

This error message is indicating that the virtual Ethernet card, “Network adapter 1,” is not supported in the current configuration of the virtual machine’s guest operating system (OS) on the host. The guest OS is the operating system that is running inside the virtual machine, and it may have specific requirements for the network adapter.

If you are encountering this error, there are a few potential solutions:

Update the virtual machine configuration: You may be able to resolve this issue by updating the configuration of the virtual machine to use a different virtual Ethernet card that is supported by the guest OS.

Install missing drivers: You can try installing the necessary drivers for the virtual Ethernet card on the guest OS. The error message suggests that this is a limitation of the virtual machine’s guest OS, so updating or installing the right drivers should resolve the issue.

Use a different host: If the issue persists, you may want to consider using a different host or virtualization software that supports the virtual Ethernet card.

I hope this information helps you resolve the issue with your virtual Ethernet card.

The above issue fixed with the below solution:

  • I removed the NIC and re-added another VMXNET3 NIC which has fixed the issue.

  • This error usually found while we try to migrate a VM. This error I noticed with a Linux Virtual Server (RHEL OS).

What is vSphere Management Assistant (vMA)?

vSphere Management Assistant (vMA) is a virtual appliance provided by VMware as part of the vSphere product suite. It is a pre-configured virtual machine that runs the Linux operating system and is used for managing and automating vSphere infrastructure.

The vMA provides a platform for executing scripts and management tools, such as vSphere CLI, vSphere SDK for Perl, and vSphere PowerCLI, without the need for a Windows-based management station. This makes it a useful tool for administrators who want to automate vSphere tasks, especially in large-scale environments where many vSphere hosts and virtual machines need to be managed.

With vMA, administrators can run scripts and tools to perform tasks such as monitoring the health of vSphere hosts and virtual machines, managing vSphere resources and configurations, and automating routine administrative tasks. The vMA also provides a secure, centralized platform for management and automation, reducing the risk of security threats and providing a more efficient way to manage vSphere environments.

Overall, the vSphere Management Assistant is a powerful tool for administrators who need to manage and automate vSphere infrastructure.
