This file is generated by engine-setup if Yes is selected for ovirt-ovn-provider, so I expect the file never existed. > How can I solve now? Remove or rename the ovirt-provider-ovn provider in oVirt Engine, if it already exsits and run engine-setup with answer-file that has 'OVESETUP_OVN/ovirtProviderOvn' enabled: 'OVESETUP_OVN/ovirtProviderOvn=bool:True' should do the trick. Didi, can you please ack that this will not destroy something except ovirt-provider-ovn related things?
