A metadata proxy server enables VMs to retrieve metadata from an OpenStack Nova API server.


  1. With admin privileges, log in to NSX Manager.
  2. Select Networking > Segments > Metadata Proxies.
  3. Click Add Metadata Proxy.
  4. Enter a name for the metadata proxy server.
  5. In the Server Address field, enter the URL and port for the Nova server.
    The valid port range is 3000 - 9000.
  6. Select an Edge cluster.
  7. (Optional) Select Edge nodes.
    If you select any Edge node, you cannot enable Standby Relocation in the next step.
  8. (Optional) Enable Standby Relocation.
    Standby relocation means that if the Edge node running the metadata proxy fails, the metadata proxy will run on a standby Edge node. You can only enable standby relocation if you do not select any Edge node.
  9. In the Shared Signature Secret field, enter the secret that the metadata proxy will use to access the Nova server.
  10. (Optional) Select a certificate for encrypted communication with the Nova server.
  11. (Optional) Select a cryptographic protocol.
    The options are TLSv1, TLSv1.1, and TLSv1.2. TLSv1.1 and TLSv1.2 are supported by default.
