| 7 | +Cumulus Linux in a virtual environment enables you to become familiar NVIDIA networking technology, learn and test Cumulus Linux in your own environment, and create a digital twin of your IT infrastructure to validate configurations, features, and automation code. |

| 9 | +## NVIDIA Air |
| 10 | + |
| 11 | +NVIDIA Air is a cloud hosted platform that works exactly like a real world production deployment. You can access NVIDIA Air {{<exlink url="https://www.nvidia.com/en-us/networking/ethernet-switching/air/" text="here">}} and reference the {{<exlink url="https://docs.nvidia.com/networking-ethernet-software/nvidia-air/" text="NVIDIA Air User Guide">}} for help. To get a jumpstart on your network configuration, you can go to the {{<exlink url="https://air.nvidia.com/marketplace" text="Demo Marketplace">}} and run one of the pre-built feature demos, such as EVPN symmetric routing, EVPN centralized routing, EVPN multihoming, and more. |
| 12 | + |
| 13 | +Cumulus Linux in a virtual environment contains the same Cumulus Linux operating system as NVIDIA Ethernet switches and contains the same software features. You have the full data plane functionality through the Linux kernel, as well as layer 2 VLANs and both VXLAN bridging and VXLAN routing capabilities. |

| 15 | +## Unsupported Features in a Virtual Environment |
| 16 | + |
| 17 | +Due to hardware specific implementations, virtual environments do **not** support certain Cumulus Linux features. |
