Public bug reported:

Listing of instances returns a limited number of resources. To list all
instances, "marker" parameter can be used to list all the pages, i.e to
obtain all the servers.

    # novaclient implements the same logic for `limit=-1`.
    results = []
    marker = None
    while True:
         servers = list_server(marker)
         if not servers:
             break

         results.extend(servers)
         marker = results[-1].id

For some reasons, it stopped working. Listing instances starting from X
instance returns a list of resources with X instance in it.

Caught by the scenario when 2 VMs are created at almost the same time
(<1sec between requests) in the same tenant by the same user, but with
different names.

- Listing of instances returns a limited number of resources. To list all instances, "marker" parameter can be used to list all the pages, i.e to obtain all the servers.
-     
-     results = []
-     marker = None
-     while True:
-          servers = list_server(marker)
-          if not servers:

-          results.extend(servers)

- Actually, novaclient implements the same logic for `limit=-1`.
- For some reasons, it stopped working. Listing instances starting from X instance returns a list of resources with X instance in it.
+          results.extend(servers)
+          marker = results[-1].id
  
- Catched by the scenario when 2 VMs are created at almost the same time
+ For some reasons, it stopped working. Listing instances starting from X
