You need to check out the matching branch to the release you've
been given as an enablement, since some of the APIs, etc, have
changed and the meta-virt sanity check that was added later than
the 2.2 release isn't working.

2.2 was the 'morty' release, and meta-virt does have a branch for
that:

----------
% git whatchanged origin/morty

commit eb6b5129561eda9ea1f47e85ab9ed9e5a6b8f64c
Author: Fabio Berton <fabio.berton at ossystems.com.br>

     python-*: use https for pypi URLs

     Several of the recipes here were using http URLs for source hosted on
     pypi - pypi apparently no longer supports http so switch to https
     instead.

     Apply this commit [1] to morty branch.

So check out the morty branch and you'll have better luck.
