"Failed to start LSB: Bring up/down networking" after OEL 7 VM build
I imported newly built OEL 7.7 VM from Oracle VirtualBox to an ODA (Oracle Database Appliance). Upon starting up the VM, the network was showing as being up for device "eth0" however the /etc/sysconfig/network-scripts/ifcfg-eth0 was existent at the moment. I restarted the network service but received the "Failed to start LSB: Bring up/down networking" error. I followed the below steps to resolve this error. 1. Stop and disable the NetworkManager service. # systemctl stop NetworkManager.service # systemctl disable NetworkManager.service 2. Enable the network service. # systemctl enable network.service 3. Create the ifcfg-eth0 and populate with the appropriate information. # vi /etc/sysconfig/network-scripts/ifcfg-eth0 contents: TYPE=Ethernet BOOTPROTO=static NAME=eth0 DEVICE=eth0 ONBOOT=yes IPADDR=<IP_ADDRESS> NETMASK=<SUBNET_MASK> GATEWAY=<DEFAULT_GATEWAY> 4. Restart the network. # ser
