Opensource private cloud selection: features and interoperability

For last few days i was working on some of the open source  cloud option. My first task was to select the best cloud orchestrator engine based on features and interoperability with hypervisor, network and storage.

   I thought about writing this blog to consolidate above concern in single post. I am considering openstack and cloudstack. infect i am a vmware guy but i am not going to mention anything about vCloud because of its hypervisor interoperability issue.  Tim Mackey has presented really great comparison for hypervisor selection for different cloud selection which is available here.  

I am going to start with cloud platform resource feature comparision with various hypervisor and then i will move forward with cloud feature availability with different hypervisor.
