thank you Matthias, i did follow what you said and i find the error,  I am connecting to vCenter server not to ESX directly and that what i have find.


Data Object Type: NotImplemented

That's the important information. The vCenter doesn't seem to implement the method to create a new volume. I wonder how a vSphere Client connected to a vCenter does volume creation. I'll have to investigate this.

seems my volume's XML needs more configurations ?

Thank You,

Works for me with the given XML config.

There might be some cases that could make it fail. For example the
.vmdk file already exists, or the datastore is full, or the datastore
is NFS backed and the ESX server lost the connection, etc.

Unfortunately libvirt doesn't include detailed information into this
error message. I'm currently improving this.

For now you can get detailed error information from the managed object
browser (mob). You can access it here:

 https://<your-esx-server-name>/mob

Then follow this chain of links: content > taskManager > recentTask
and pick the last item in the list. It should be named like this:

 haTask--vim.VirtualDiskManager.createVirtualDisk-88

This is probably the failed .vmdk creation task. Then follow this
second chain of links: info > error to get more detailed error
information.

As said the next libvirt release will include this more detailed
information in error messages for failed tasks.
