VMX file path format and read permission for the file

The problem we currently have is connecting to VMs using the VIX API.

The API has a method VMOpen :

($err, $vmHandle) = VMOpen($hostHandle,

$vmxFilePathName);

This function opens a virtual machine on the host that is identified by the hostHandle parameter and returns a context to that machine as a virtual machine handle.

We have the hostHandle. But, I think we are sending a wrong path name for the vmx file.

The format we currently use is

my $vmxFilePathName = "/vmfs/volumes/datastore_name/lab_manager_name/folder_name/somefile.vmx"; 

I have read permissions on the datastore. But, the error I am getting is 3014, Insufficient privileges.

Any help in this regard would be appreciated.

Thanks,

Sri.
