[Belmiro Moreira <1533380@xxxxxxxxxxxxxxxxxx>]

Public bug reported:

When creating multiple instances with a single request the instance name has the format defined in the "multi_instance_display_name_template" option.
By default: multi_instance_display_name_template=%(name)s-%(count)d
When booting two instances (num-instances=2) with the name=test is expected to have the following instance names:
test-1
test-2

However, if using cells (only considering 2 levels) we have the following names:
test-1-1
test-1-2

Increasing the number of cell levels adds more hops in the instance name.
Changing the "multi_instance_display_name_template" to uuids has the same problem.
For example: (consider <uuid> a random uuid)
test-<uuid1>-<uuid1>
test-<uuid1>-<uuid2>
