Hi, 
I worked with Cloudstack too, Cloudstack use the vCenter for launch the VM's, destroy, etc. That is a good idea but you depend, always, for the good funcionality of vCenter. 

The Information for Openstack is so short: 
http://docs.openstack.org/trunk/openstack-compute/admin/content/VMWare_configuration_options.html 

But i readed a good message before, this:

Asunto: [Openstack] Using VMWare ESXi with openstack 

Hi 


I tried to see how we can control any existing infrastructure of VMWare/XenServer etc from openstack. 
What i understood is that nova compute needs to be installed on the hypervisors(compute hosts) which can be Ubuntu Servers for KVM etc. 
Also for XenServer, we can build a package on Ubuntu and then will have to install on XenServer so that it can be controlled by cloud controller. 


Basically openstack compute should be installed on hypervisor and accepts the instructions from controller to create VM's, assign IP addresses, destroy, attaching volumes etc. 
Please confirm this understanding. 


Based on this, i did not find anything on VMWare ESXi. How does the compute gets installed on ESXi server ? 


Also, i have seen cloudstack working which seems to be little different than how openstack works. Cloudstack can control existing VMWare/XenServer/KVM etc using their respective API's. 
It doesnt require any installation on the hypervisor itself. If my understanding is correct, then this seems to be a better model. 
What is the reason that openstack cannot operate the hypervisors without installing compute on them ? 


Thanks 
Atul
