When we try to use ignition and provide only the UI fields without any payload, the engine will result in a bad payload. This will cause the ignition to fail in the OS.
This bug is in modified and targeting 4.4.1. can we retarget this to 4.4.0 and move to QE?
Verified with: - RHV 4.4.0-0.33.master.el8ev - rhcos-44.81.202004250133-0-openstack - libvirt-6.0.0-17.module+el8.2.0+6257+0d066c28.x86_64 - vdsm-4.40.13-1.el8ev.x86_64 Verification steps: 1. Create an RHCOS VM from a template (it doesn't have to be created from a template). 2. Go to 'Edit > General' and set 'Red Hat Enterprise Linux CoreOS' as the Operating System. 3. Go to 'Edit > Initial Run' and check the 'Ignition 2.3.0', remove the default value from 'VM Hostname' field and make sure other fields empty as well 4. Start the VM Result: - The vmPayload sent (see below) and the VM is up and running (the OS, of course, is not accessible due to missing auth-configurations supposed to be sent by the ignition) # virsh -r dumpxml <rhcos_vm> | sed -n '/ovirt-vm:vmPayload/,/\/ovirt-vm:vmPayload/p' <ovirt-vm:vmPayload> <ovirt-vm:volId>config-2</ovirt-vm:volId> <ovirt-vm:file path="openstack/latest/meta_data.json">ewogICJhdmFpbGFiaWxpdHlfem9uZSIgOiAibm92YSIsCiAgImxhdW5jaF9pbmRleCIgOiAiMCIsCiAgIm1ldGEiIDogewogICAgInJvbGUiIDogInNlcnZlciIsCiAgICAiZHNtb2RlIiA6ICJsb2NhbCIsCiAgICAiZXNzZW50aWFsIiA6ICJmYWxzZSIKICB9LAogICJ1dWlkIiA6ICIxYTkwNTA3Zi03MzllLTRmNWMtOWI5NS1mNWEzODk4ZmJiZGIiCn0=</ovirt-vm:file> <ovirt-vm:file path="openstack/latest/user_data">eyJpZ25pdGlvbiI6eyJ2ZXJzaW9uIjoiMi4zLjAifX0=</ovirt-vm:file> </ovirt-vm:vmPayload> Note: I didn't verify with run-once due to a bug with missing payload when running an RHCOS VM in run-once mode https://bugzilla.redhat.com/show_bug.cgi?id=1828132
