No you don't need to run this tools.

OK. Understood.
you don=E2=80=99t have to, but you=E2=80=99ll get a better, cleaner, =

It may make sense to use it for initialization during deployment as well =
as a replacement of cloud-init not requiring you to initialize it by =
running it. You would have to do it yourself, making sure the image is =
not in use while the operation is ongoing.
I think it would also be nice to completely integrate it into =E2=80=9Ccre=
ate VM from Template=E2=80=9D flow. You would have a ready-to-go VMs =
customized at the time of creation already, instead of relying on =
runtime cloud-init
Thanks,

What do you mean by sealing?
=20
=20
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:
=20
TYPE=3DEthernet
BOOTPROTO=3Dnone
DEFROUTE=3Dyes
IPV4_FAILURE_FATAL=3Dno
IPV6INIT=3Dno
IPV6_AUTOCONF=3Dyes
IPV6_DEFROUTE=3Dyes
IPV6_PEERDNS=3Dyes
IPV6_PEERROUTES=3Dyes
IPV6_FAILURE_FATAL=3Dno
NAME=3Deth0
UUID=3D5a656c34-e4ba-44a1-8079-d2c797e6a8f4
DEVICE=3Deth0
ONBOOT=3Dyes
IPADDR=3D10.4.4.29
PREFIX=3D24
GATEWAY=3D10.4.4.250
DNS1=3D10.4.1.11
DNS2=3D10.4.1.12
DOMAIN=3D"mysearchdomain1.com <http://mysearchdomain1.com/> =
mysearchdomain2.com <http://mysearchdomain2.com/>"
=20
While an old style (managed by classic "network" service) entry sholud =
be something like:
=20
DEVICE=3Deth0
TYPE=3DEthernet
BOOTPROTO=3Dstatic
ONBOOT=3Dyes
IPADDR=3D10.4.4.29
PREFIX=3D24
GATEWAY=3D10.4.4.250
=20
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?
