We're using cloud-init to customize VMs built from a template. We're using =
static IPV4 settings so we're specifying an IP address, subnet mask, and ga=
teway. There is apparently a bug in the current version of cloud-init shipp=
ing as part of CentOS 7.4 (https://bugzilla.redhat.com/show_bug.cgi?id=3D14=
92726) that fails to set the gateway properly. In the description of the bu=
g, it says it is fixed in RHEL 7.5 but also says one can use https://people=
.redhat.com/rmccabe/cloud-init/cloud-init-0.7.9-20.el7.x86_64.rpm which is =
what we're doing.
When the new VM first boots, the 3 IPv4 settings are all set correctly. Reb=
oots of the VM maintain the settings properly. But, if the VM is shut down =
and started again via the oVirt GUI, all of the IPV4 settings on the eth0 v=
irtual NIC are lost and the /etc/sysconfig/network-scripts/ifcfg-eth0 shows=
that the NIC is now set up for DHCP.
Are we doing something incorrectly?
