Issue/Introduction

VMSP virtual machine is failing to acquire an IP address on the network

Checking file /etc/systemd/network/10-eth0.network is owned by user other than systemd-network

Environment

VCF 9.1

Cause

Incorrect permissions are applied to /etc/systemd/network/10-eth0.network

Resolution

 

To resolve follow the steps below:

1. Access the VMSP VM console directly via the vSphere Client.

2. Validate the current file permissions and ownership of the network configuration file: ls -la /etc/systemd/network/10-eth0.network

3. Modify the file permissions to ensure adequate read access for the network daemon (Standard permissions require 644): chmod 644 /etc/systemd/network/10-eth0.network

4. Verify the file ownership is properly assigned (typically root:systemd-network): chown systemd-network:systemd-network /etc/systemd/network/10-eth0.network

5. Restart the network daemon to reload the configuration file: systemctl restart systemd-networkd

6. Confirm the IP address has been allocated and the interface is up: ip a show eth0
