Public bug reported:

Openstack version: Kilo.

We are configuring openstack/vmware w/ multiple datastore.
We also applied this patch: https://review.openstack.org/#/c/186716/

But we got an error when booting instances.

What we do:
1. Configure glance-store backend as vsphere
2. Create an image in glance. It is stored in vsphere://172.20.2.38/folder/openstack_glance/58f446bb-35da-4aca-9532-c33c8562e2c2?dcPath=IDC_Test&dsName=LUN03-00
3. Boot an instance with this image.

We failed at Step-3:

Radoslav Gerganov confirms nova/virt/vmwareapi/vmops.py has a bug:

    def _prepare_sparse_image(self, vi):
        tmp_dir_loc = vi.datastore.build_path(
                self._tmp_folder, uuidutils.generate_uuid())
        tmp_image_ds_loc = tmp_dir_loc.join(
                vi.ii.image_id, "tmp-sparse.vmdk")
        return tmp_dir_loc, tmp_image_ds_loc

should be:

def _prepare_sparse_image(self, vi):
    tmp_dir_loc = vi.datastore.build_path(
            self._tmp_folder, uuidutils.generate_uuid())
    tmp_image_ds_loc = tmp_dir_loc.join(
            vi.ii.image_id, "tmp-sparse.vmdk")
    ds_util.mkdir(self._session, tmp_image_ds_loc.parent, vi.dc_info.ref)
    return tmp_dir_loc, tmp_image_ds_loc

This issue is gone after we make the changes.
