Using MAAS 2.2.2 and newest CentOS image that uses cloud-init cloud-init-0.7.9+224.g681baff-1.el7.centos.noarch, network configuration re-created after reboot.

The configuration created was:

[centos@withkvm ~]$ cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Created by cloud-init on instance boot automatically, do not edit.
#
BOOTPROTO=dhcp
DEVICE=eth0
HWADDR=52:54:00:03:02:6e
NM_CONTROLLED=no
ONBOOT=yes
TYPE=Ethernet
USERCTL=no

I changed that to do:

[centos@withkvm ~]$ cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Created by cloud-init on instance boot automatically, do not edit.
#
BOOTPROTO=static
DEVICE=eth0
HWADDR=52:54:00:03:02:6e
NM_CONTROLLED=no
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
IPADDR=192.168.122.3
NETMASK=255.255.255.0
GATEWAY=192.168.122.2

However, after I reboot, the network config is changed:

[centos@withkvm ~]$ sudo cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Created by cloud-init on instance boot automatically, do not edit.
#
BOOTPROTO=dhcp
DEVICE=eth0
HWADDR=52:54:00:03:02:6e
NM_CONTROLLED=no
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
