 OK. Understood.

I mean what are the correct modifications t apply to the OS, before makeing
it a template and then create a VM from that template using cloud-init.
For example:
a NetworkManager enabled configuration for ifcfg-eth0 file is somethng like
that on RH EL 7:

TYPE=Ethernet
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=no
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eth0
UUID=5a656c34-e4ba-44a1-8079-d2c797e6a8f4
DEVICE=eth0
ONBOOT=yes
IPADDR=10.4.4.29
PREFIX=24
GATEWAY=10.4.4.250
DNS1=10.4.1.11
DNS2=10.4.1.12
DOMAIN="mysearchdomain1.com mysearchdomain2.com"

While an old style (managed by classic "network" service) entry sholud be
something like:

DEVICE=eth0
TYPE=Ethernet
BOOTPROTO=static
ONBOOT=yes
IPADDR=10.4.4.29
PREFIX=24
GATEWAY=10.4.4.250

Do I have to make any modification in both case to ifcfg-eth0 just before
making template or should I leave the original VM values inside?
Does cloud-init provided by oVirt with the values I put inside the GUI
during VM creation replace files using something like "sed" command or does
it run any network-config operating system commands?
