I'm guessing we could borrow/steal a lot from what was done by the people who participated in "virt-blocks" last fall. Andrea - any advice/suggestions to give here?


It would be of great help if we can get "inspiration" from another project to get the initial CI/unit test
skeleton.

I'd rather put it under a personal gitlab tree first. Putting it inside Libvirt umbrella might generate
unrealistic expectations for something that's still on its infancy.

This is always the toughest part for me, since it is what the rest of the world sees, so it needs to be intelligible and capable of expansion, and I have a long history of making questionable choices that come back to haunt me (and everybody else! :-P). Since danpb has made good decisions in this area in the past (and since the original proposal is his), I'm thinking/hoping he can help provide direction to minimize mis-steps (on the other hand, I know he's really busy, so maybe he was just hoping that someone else would grab up his proposal and run with it).


My initial plan is to get the logic/APIs design from Libvirt, rename them in a Gopher fashion, re-code
it with Go and call it a day :)

In all seriousness, we have some room to do "not so good" APIs and change them if necessary since it's
a fresh project. In this stage we can start with simplified versions of the use cases danpb described
in the first email of the thread and play by ear.



Thanks,
