Subject Re: understanding cloudstack networking
Date Mon, 12 Aug 2013 16:49:42 GMT
I'm just going to chime in on this. What we need to put together is a primer. Our docs work
fairly well and are CloudStack centric, which I see as most peoples issue. On the topic of
networking, building a cloud requires a very strong understanding of core Linux networking,
which is technically outside the responsibilities of our project. This does not mean however
that community members can not create primer guides, and many have... There is mostly a difficulty
in new users finding these resources.

On the topic of 4.2, we all knew some big changes were coming, but it did feel like a couple
strange housekeeping items snuck in under the radar that affected how certain components work.
An example of this would be the new network interface handling from a user perspective.

I am more then happy to assist people with install and setup issues on the networking side
of things, as collecting data on what parts of the process are most difficult would be quite
valuable to us.

sounds great Ron,

I'm sure I am not the guy you need for this but I'll keep an eye on
it. The 'someone who actually knows what it s supposed to say' is
bound to be around on this list or dev.
