Hello, And first thanks for your help with my precedent problem (bug in a file workflows.py in Dalmatian). I noticed another behavior with problem: First: (venv) user1@pc1:~$ openstack subnet show demo-subnet +----------------------+--------------------------------------+ | Field | Value | +----------------------+--------------------------------------+ | allocation_pools | 10.0.0.2-10.0.0.254 | | cidr | 10.0.0.0/24 | | created_at | 2025-04-16T11:23:11Z | | description | | | dns_nameservers | 172.16.0.200 | | dns_publish_fixed_ip | None | | enable_dhcp | True | | gateway_ip | 10.0.0.1 | | host_routes | | | id | a3f6bd66-74ce-4060-9063-c357ce1b9a5a | | ip_version | 4 | | ipv6_address_mode | None | | ipv6_ra_mode | None | | name | demo-subnet | | network_id | 01a712ac-a392-4c70-b485-083b0cde7876 | | project_id | 7b425dfb90024da8946a83b944d9adf4 | | revision_number | 0 | | router:external | False | | segment_id | None | | service_types | | | subnetpool_id | None | | tags | | | updated_at | 2025-04-16T11:23:11Z | +----------------------+--------------------------------------+ In my demo subnet, DHCP is enable, so « enable_dhcp = True » is OK. In Horizon, OK, we can see this:  But in another view of the net and subnet: DHCP enabled is NO  I didn't have this with previous versions. Is this another bug? If so, I haven't found it. Thanks in advance for your help on this. Franck
