Might be vmid is missing between "var" and "deployment.0". I am making the required changes  in OneVmmVmware.java to refer the right path $ONE_LOCATION/var/<vmid>/deployment.0

That is strange, since OpenNebula will pass to the driver something like

$ONE_LOCATION/var/<vmid>/images/deployment.0

and then the driver will remove the "/images". Could you tell us what
do you have in the "str" variable after line 87 ("str=in.readLine()").

In ESX hypervisors the datastore is located in
/vmfs/volumes/<datastore_name>. In VMware server the prefix may vary,
look in your filesystem for the <datastore_name>.

Couyld you send over the $ONE_LOCATION/var/oned.log? That may be a
connection problem.

I need to test it under vmware server and probably make some changes. Meanwhile, if you point me what is the path to the DATASTORE in your vmware server I may be able to provide a quick patch.
