Hello, I've a little problem, when I run an instance, I've no IP address in interface of my instance. I currently have a single node installation of openstack grizzly running

I put in /etc/nova/nova.conf

dhcpbridge = /usr/bin/nova-dhcpbridge

dhcpbridgeflagfile =/etc/nova/nova.conf metadatahost =172.16.118.200

network_host=172.16.118.200

routingsourceip=172.16.118.200

fixed_range=10.12.0.0/24

network_size=256

flatnetworkbridge=br0

flat_interface=eth0

flat_injected=False

I can launch, display and configure an IP address to my interface eth0 but I can find my adress with the DHCP.

Somebody have maybe an idea?

To deploy my instance I did:

nova-manage floating create 172.16.118.201

nova-manage network create private --fixedrangev4=10.12.0.0/24 --numnetworks=1 --bridge=br0 --bridgeinterface=eth2 --network_size=256

-- Creation of keypair --

nova keypair-add keypairtest > keypairtest.pem

chmod 600 keypair_test.pem

nova boot --image 083a52e0-b333-42c0-811f-41265dba7883 --flavor 0d16c089-2fd4-455e-bef5-f521f945a2f8 --key_name test instance1 --poll

nova floating-ip-create

nova add-floating-ip instance1 172.16.118.201

Did you create network:

nova-manage network create private --fixed_range_v4=10.12.0.0/24 --bridge_interface=br0 --num_networks=1 --network_size=256

Also in above configuration put:

network_manager=nova.network.manager.FlatDHCPManager
