Hi All! I'm trying to configure network in VMs created from template, and see strange behaviour from cloud-init. cloud-init installed and enabled in template. ver cloud-init-0.7.9-24.el7.centos.1.x86_64 guest Centos 7.5 ovirt 4.2.7 from ovirt-releases-42-pre repo 1. I use "run once" with initial run - use cloud-init - networks in-guest net iface : eth0 add new - static enter address, mask, gw ipv6 none Run (once) and cloud-init configure ifcfg-eth0 for that address (successfully). 2. I shutdown that VM and use "Run" (regular) without "use cloud init" in VM properties, awaiting that above configurations are saved (and booted with it). But because "use cloud init" not checked, and cloud-init service enabled, it start, cannot find datasource and drop configuration to default (dhcp). In cloud-init.log 2018-11-20 13:53:24,153 - util.py[WARNING]: No instance datasource found! Likely bad things to come! 2018-11-20 13:53:24,153 - util.py[DEBUG]: No instance datasource found!
