Comment 1 for bug 1614090

Diagnostic snapshot analysis revealed that there is an infrastructure problem:
NFS datastore is not available that is used by Glance backed (vmware_datastore).

Things goes this way:
openstack client tries to upload Cirros image into Glance.
Glance is configured with vmware_datastore (uses remote that is
available via vCenter server) as backend, but it cannot use it because
it is unavalable. Here is a snippet from glance-api.log

Possible hypothesises are network connectivity problems or NFS host is down.

Marking as invalid.
