Open Stack

Hi All,

I have configured Openstack Grizzly to use ESXi 5.1 as hypervisor. 
Creating/deleting instances from Openstack
works as expected, instances are created in ESXi ( Verified via vSphere 
Client) and started ok.  The trouble is that
VMs are unable to configure internal IP.  Does quantum have a way to 
reach vmware api to configure network.
Does quantum plugin for vmware/esx exist?

What could be possible solution for this? Any help would be really 
appreciated.

Thanks in advance.

Regards,
