Static IP address is not configured when deploying a new Cloud Director Availability appliance

Products

• VMware Cloud Director

Issue/Introduction

Symptoms:

• A new Cloud Director Availability appliance is deployed with a static IP address configured in the OVF properties.
• In the console, you see the following message while booting the system:
   
  [FAILED] Failed to start vCAv network initializer
  See 'systemctl status h4network.service' for details.
   
• After initial startup of the appliance, the IP address specified for connecting to the device is the default loopback adapter address: 127.0.0.1
• In the console screen on the running appliance, you see the error:
   
  Unable to apply network adapter settings.
  Run 'jounalctl -u h4network' for more info.
  Use '/opt/vmware/h4/bin/net.py' to manually apply the network settings.
   
• When reviewing the system logs for the h4network service (i.e., using the command journalctl -u h4network), you see an output similar to:

Environment

VMware Cloud Director Availability 4.x

Cause

This issue occurs when configuring the static IP address during the deployment of the Cloud Director Availability appliance OVA, a valid CIDR subnet prefix was not provided with the specified host IP address.

Resolution

To resolve this issue, either redeploy the appliance or reconfigure the network adapter with the correct CIDR format.

Option 1

Redeploy the appliance and specify the IP address for the device using the correct CIDR format. For example, when configuring the appliance with an IP address of 192.168.0.10 and a subnet of 255.255.255.0, the following would be specified: 192.168.0.10/24.

Option 2

Run the /opt/vmware/h4/bin/net.py command with the appropriate parameters. For more information on using this command, see the Command-Line Network Configuration section of the Cloud Director Availability documentation.
