contributions to make python-tempestconf smarter - being able to discover
more relevant configuration are always welcomed.
In regards of resource creation, I'd probably stick with the current
resources (images and flavors) and wouldn't complicate it with more such as
I think it would be better if you would create any network resources you
need prior python-tempestconf execution, I expect that something like that
will have more logic (code) which increases maintenance requirements - it
will be better also for you if you have more control over it.
Speaking about flavors, we already support ram and disk modifications so I
think that we could add one more option through which a user could pass
custom parameters (*like hw:mem_page_size* you mentioned) to the flavors.
Btw, check out ansible-role-os_tempest, it's basically a role/wrapper
around tempest and python-tempestconf. It creates basic network resources
and some other stuff in order to prepare for tempest execution.
