Network Issues in VMware Aria Operations for Logs

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

• VMware Aria Operations for Logs nodes fail to boot due to a loss of network connectivity. The affected node's console in vCenter Server displays the error: "NO NETWORK DETECTED. PLEASE CHECK THE NETWORK CONFIGURATION"
  
  
• The network configuration is successfully propagated from vApp properties to the networking daemon configuration file (/etc/systemd/network/10-eth0.network) on each VMware Aria Operations for Logs node.
  However, when running ifconfig the eth0 interface shows "No carrier".
  This typically indicates the virtual Ethernet cable is not connected to the virtual Ethernet port of the virtual machine.
