After importing an Oracle Virtual Appliance file (.ova) on my new machine and starting the OpenFiler VM, i received below error:

This is how i troubleshooted it.

Login as root user.

cat /etc/sysconfig/network

cd /etc/sysconfig/network-scripts/

Restart the service as below:

service openfiler –full-restart 

The real problem is here:

This is a post cloning problem. The cloned VM was still using the old machine’s MAC address in Virtual Machine settings.

Open config files for eth0 and eth1, and copy the MAC address from there.

cat /etc/sysconfig/network-scripts/ifcfg-eth0

HWADDR=08:00:27:85:1F:65

cat /etc/sysconfig/network-scripts/ifcfg-eth1

HWADDR=08:00:27:D3:F9:38

Power Off the virtual machine and update the MAC address under network settings.

Reboot the VM and this resolved the issue.
