Try specifying BRIDGE_LIST="localhost" directly in OpenNebula, eg, in your ds.conf

Thanks it worked. Datastor created
But now the driver does not work
Shows zero storage values.

@lazy-pepper please try if it changes if you create the dataset you gave in the config using zfs create pool/dataset/name.
I had to wait a few monitor cycles for it to work in the end.

(Oh wow does the output formatting suck)
