NSX Edge deployment fails with error "The provided network mapping between OVF networks and the system network is not supported by any host."

Products

• VMware NSX

Issue/Introduction

• Attempting to deploy an Edge using the REST API.
• No error is returned by the API, but "Deployment Failed" is displayed when checking [System] > [Fabric] > [Nodes] > [Edge Transport Nodes] in the GUI.
• Clicking "Deployment Failed" displays the following error: "Ovf deploy for vm ########-####-####-####-######## failed on vc ########.##.## : The provided network mapping between OVF networks and the system network is not supported by any host."

• Checking /var/log/proton/nsxapi.log shows the following message output immediately before the error message, and the list at the end does not contain the network specified in data_network_ids of the API body:

Environment

VMware NSX

Cause

This error occurs when the network specified in data_network_ids is not included in the list of available networks for the hosts associated with the specified deployment target cluster or resource pool.

The cause may be an incorrect specification of the target cluster or resource pool for deployment.

Resolution

In the request body of the executed API, verify that the network is available on the hosts within the specified cluster or resource pool.

If possible, consider deploying through the GUI. When using the GUI, only the networks selectable by hosts within the chosen cluster or resource pool are displayed as options, which helps prevent this type of mistake.
