Hi,
Here are my answers to your questions:
- How powerful is pyshpere compared with the both of them (more or less features, strong points, weak ones...)?
To be honest, I haven't used CLI nor PowerCLI. But I've tried other python vSphere implementations and found pysphere to be much faster.
In terms of usability, pysphere is tailored to ease specially Virtual Machine operations. In the company I work for, we use it mainly for test cases automation. Basically we revert VMs to snapshots with vulnerable software, pen test them, and see if the exploits work. So we use a lot the recently added guest operations (to trigger client-side exploits or automatically installing new vulnerable software in a snapshot). That's why pysphere presents simplified interfaces for VM operations for which you don't need to know anything about vSphere.
However you can use it to implement any method or retrieve any property from vSphere, which requires of course a more advance knowledge of both, pysphere and the vSphere SDK (you can check the source code to see how the simplified VM operations are implemented).
CLI and PowerCLI rely on the vSphere SDK, then I think that pysphere should support the same or more features than them.
I'm still writting the documentation but you can find more info in the project's site.
- How stable is? It is in production ready stage?
We've been using it for more than a year against a Virtual Center with ~12 ESXs connected to it (about 1500 VMs). But, as you mention, is not supported by VMWare so you should use it at your own risk.
- Who are the mantainers/coders involved in the project?
Just me for the moment, I had a couple of simple code contributions from the people that started using it. The project is pretty new on google so I hope to get more contributors.
Hope this helps.
Regards.
