[ovirt-users] info about changing engine ip mode from dhcp to static

Hello, a colleague of mine installed oVirt engine 4.2.5 on a test CentOS 7.5 system and in its initial configuration he configured its ip via dhcp (using static ip assignment configured at dhcp server side). Now he would like to maintain the same ip/hostname for the engine but with a static configuration on the server. Any hint about how to achieve this? Thanks in advance, Gianluca
