I'm trying to add a host running Fedora 28 to engine 4.2, and installation
fails with:

2018-06-20 01:14:26,137+0300 DEBUG otopi.context context._executeMethod:143 method exception
Traceback (most recent call last):

2018-06-20 01:14:26,138+0300 ERROR otopi.context context._executeMethod:152 Failed to execute stage 'Environment packages setup': Packager install not implemented

Do we have a way to workaround this?

I must have a host when I can build and test virt-v2v upstream from source,
and virt-v2v requires python 3. So I need some workaround to get the host
connected to engine.
