Hi Ján,

Thanks a lot for the suggestion. It worked and volume is added to the datastore. Now if I try to start the node it gives an error saying:

Error: internal error: Could not start domain: FileNotFound - File [datastore1] testNode/cluster.vmdk was not found."

But .vmdk file exist at this location. What is going wrong here can anyobe plz suggest. Below is my xml:

<domain type='vmware'>
  <name>testNode</name>
