It's allowed to create duplicate sg with the same name.
so exception happens when creating instance with the duplicate sg name.
code following:
....
security_groups = kwargs.get('security_groups', [])
security_group_ids = []
# TODO(arosen) Should optimize more to do direct query for security
# group if len(security_groups) == 1
if len(security_groups):
search_opts = {'tenant_id': instance['project_id']}
user_security_groups = neutron.list_security_groups(
**search_opts).get('security_groups')
for security_group in security_groups:
name_match = None
uuid_match = None
for user_security_group in user_security_groups:
if user_security_group['name'] == security_group:
if name_match:---------------exception happened here
raise exception.NoUniqueMatch(
_("Multiple security groups found matching"
" '%s'. Use an ID to be more specific.") %
security_group)
name_match = user_security_group['id']
....
so it's maybe improper to create instance with the sg name parameter.
appreciation if any response.
