Open Stack

Hello everyone,

I am trying to understand the flow of control in code in openstack for 
provisioning a VM. I want to understand it in order to do modify scheduler 
module as per our requirements. 

I have found the code base which, if I am not wrong, is kept in 
/usr/share/pyshared/nova/* directory but I can't see .py files getting 
accessed or executed if I provision a VM.

Can someone please help me to understand the flow of code or give me 
pointers from where I can understand it. I hope even if I know the 
starting point (REST handler for VM provisioning call) in code then I will 
be able to trace it.

Thanks

Regards
Deepak
