Comment 5 for bug 1884018

It looks like it's two separate bugs here, one for the OpenStack provider and the other for Azure (unless it's also the bit of code to include the AZ that's causing an issue with Azure too?).

Should we split this into two bugs or keep it as one?

For OpenStack, in our set up there's only a single AZ for cinder:

$ nova availability-zone-list
+------------------+---------------+
| Name | Status |
+------------------+---------------+
| prodstack-zone-2 | available |
| prodstack-zone-1 | available |
| nova | not available |
+------------------+---------------+

$ cinder availability-zone-list
+------+-----------+
| Name | Status |
+------+-----------+
| nova | available |
+------+-----------+

Unlike with compute, where there are two and the default one 'nova' disabled.
