Which version of otopi? Gal (added) is currently working on fedora/python3 support for the stuff we (integration-development team) maintain, including otopi. Several relevant patches were merged in recent weeks, please update. That said, I still do not consider fedora 28/python 3 "supported" - in particular, I have no idea what the status of host-deploy is. > > I must have a host when I can build and test virt-v2v upstream from source, > and virt-v2v requires python 3. Must it have /usr/bin/python be python3? > So I need some workaround to get the host > connected to engine. Must this be on fedora? You can have python 3(.4) on el7 from epel. You can have even newer ones from SCL. If you do want/need fedora, please update to latest otopi on your engine machine, make sure the bundle is updated, e.g. by removing it: rm /var/cache/ovirt-engine/ovirt-host-deploy.tar Then try to add the host, and share the host-deploy log. Thanks.
