*i just want to understand as to how the request goes from the api-call to
the nova-api and so on after that.*
To answer "so on after that", in addition to josh answer, you can also look
into

.

Now to answer first part, "i just want to understand as to how the request
goes from the api-call to the nova-api":
You can look into *http://developer.openstack.org/api-ref.html
<http://developer.openstack.org/api-ref.html>*, particularly in
*http://developer.openstack.org/api-ref-compute-v2.1.html
