[ovirt-devel] ovirt-provider-ovn - appliance inclusion / default enablement

Hi, with https://gerrit.ovirt.org/76855 it's requested to increase the appliance size by adding ovirt-provider-ovn and its dependencies. This raise a few questions. The support for ovirt-provider-ovn is enabled by default in engine-setup and going to be installed by default in the appliance so we're pushing to use it. Why not requiring it at ovirt-engine spec file level? Answer given in the commit message of above patch is: We do not want to have a hard dependency in the form of an rpm require. OVN and openvswitch are relatively heavy and complex, and are still experimental. We would not want to force everybody to pull them onto any Engine host. So why adding it to the appliance, which is the default for hosted engine which is our recommeded way to deploy oVirt, and enable it by default? How this differs from DWH? ovirt-engine requires ovirt-engine-setup which requires ovirt-engine-dwh setup which requires ovirt-engine-dwh. Why can't we just require ovirt-provider-ovn in ovirt-engine instead of tweaking the appliance? If we decide it's not mandatory, why not make the default to not enabling it in engine-setup and avoid to add it to the appliance? Being optional, adding it collides with Bug 1401931 <https://bugzilla.redhat.com/show_bug.cgi?id=1401931> - [RFE] reduce the size of the appliance Thanks, -- SANDRO BONAZZOLA ASSOCIATE MANAGER, SOFTWARE ENGINEERING, EMEA ENG VIRTUALIZATION R&D Red Hat EMEA <https://www.redhat.com/> <https://red.ht/sig> TRIED.
