> Hi,
>
> I'm trying to trace a request made for an instance and looking at the flow
> in the code.
> I'm just trying to understand better how the request goes from the
> dashboard to the nova-api , to the other internal components of nova and to
> the scheduler and back with a suitable host and launching of the instance.
>
> i just want to understand as to how the request goes from the api-call to
> the nova-api and so on after that.
> I have understood the nova-scheduler and in that, the filter_scheduler
> receives something called request_spec that is the specifications of the
> request that is made, and I want to see where this comes from. I was not
> very successful in reverse engineering this.
>
> I could use some help as I want to implement a scheduling algorithm of my
> own but for that I need to understand how and where the requests come in
> and how the flow works.
>
> If someone could guide me as to where i can find help or point in some
> direction then it would be of great help.
