I have been working on other things which are not Linux related so obvious things have reached the area of “oh….the answer is……”
A question was raised about a Linux virtual machine using DHCP. I remembered it wasn’t but I blanked on where to look for the answer.
Simply look in the file: /etc/sysconfig/network-scripts/ifcfg-eth0
Look for:
BOOTPROTO=dhcp
ONBOOT=yes
That shows DHCP is in use.
