Hi I tried restarting both neutron-service, dhcp agent and openvswitch agent But now when I create a new network and launch instances DHCP agent wont start anymore 2014-12-09 16:51:34.472 13703 WARNING neutron.agent.dhcp_agent [req-df6e4f47-2040-4bf2-9ea7-fac027e0ff28 None] Unable to enable dhcp for 55a76ce1-39e4-49fb-9951-6d31318ea86f: there is a conflict with its current state; please check that the network and/or its subnet(s) still exist. On a different node why is this a warning and not a critical error Ajay From: <Gangur>, "Hrushikesh (R & D HP Cloud)" <hrushikesh.gangur at hp.com<mailto:hrushikesh.gangur at hp.com>> Date: Monday, December 8, 2014 at 10:48 PM To: akalambu <akalambu at cisco.com<mailto:akalambu at cisco.com>>, "openstack at lists.openstack.org<mailto:openstack at lists.openstack.org>" <openstack at lists.openstack.org<mailto:openstack at lists.openstack.org>> Subject: RE: Changing ML2 vlan range You just need to restart neutron-server service.
