Oh. I still want to have OVN by default for non-appliance. I like this feature, and I want to entice people to use it. For appliance I understand that we have a size limitation, so ok, let us not bloat it up. I hope you are also fine with disabling ovn in the following answer file. > > The appliance-supplied answer file seems is: > > https://gerrit.ovirt.org/gitweb?p=ovirt-appliance.git;a=blob;f=engine-appliance/data/ovirt-engine-answers;h=2881af6563297a7a3d220dfe479d39f88c12ca46;hb=HEAD > > When hosted-engine --deploy is using the appliance, and if the user > asks to run engine-setup automatically, it uses above file, > but also adds another file, auto-generated, see here: > > https://gerrit.ovirt.org/gitweb?p=ovirt-hosted-engine-setup.git;a=blob;f=src/plugins/gr-he-common/vm/cloud_init.py;h=0a20f946d65199423c99769ab51e4fe092465e96;hb=HEAD#l1018 > > None of them has the answer for OVN.
