Description Ryan Barry 2019-05-22 07:58:07 UTC

+++ This bug was initially created as a clone of Bug #1691704 +++

Request for enhancement:

To start give support to Openshift4 and OKD4, we need to add ignition support for RHEV vms in order to allow the openshift-installer to scale up and down nodes using oVirt as a base platform.

i believe https://gerrit.ovirt.org/#/c/100008 can be used as a workaround

--- Additional comment from Roy Golan on 2019-05-22 07:47:45 UTC ---

The merged patches to the engine supply support over cloud-init cdrom, which is a well known and used
method for a long time.

Currently the way to use it is to pass the ignition config into the 'custom script' section of the vm init object
when creating the vm. If the config file is a valid json file with the ignition key in it, it will be passed to
on into the userdata file under the config-2 disk.

RHCOS side needs to have the openstack ignition enabled in the kernel so it will boot and try to locate 
the config-2 disk - its location will be /dev/disk/by-label/config-2 . The ignition provider mounts it
and then the config data available to ignition.
This means the VM template should be openstack RHCOS image.

Regarding fw_cfg, it doesn't have support from qemu at the moment, and moreover I don't see it supporting large
ignition config files, where in the case of openshift installation, the bootstrap ignition data is 300k big.
