When creating a custom template where I replace running: true with runStrategy: RerunOnFailure and then attempt to quick create a VM from that template. The UI displays an error `Error "Running and RunStrategy are mutually exclusive" for field "spec.running"`. 

4.14, and 4.15

100%

1. Create a custom template based on one of the existing ones. I picked the fedora template and make a copy of it and modfied running: true to runStrategy: rerunOnFailure. I saved it in default namespace.
2. I attempted to quick create a VM from this new template. When clicking create I get the mentioned error message.
3. I checked the generated yaml in the dialog and it looks perfectly fine. I can download the yaml and apply it with the cli and the generated VM starts fine.

Error message about a field that doesn't exist in the yaml

VM is created as expected

The generated yaml passed validation on the backend and is able to start. It is just the UI that prevents creation of the VM.
