[Openstack] nova-manage network create does not create the bridges/vlans immediately

Hi, i am trying to deploy a VlanManager networking model in Essex, i am 
not using Quantum, and my problem is when i try to do:

nova-manage network create --label vlan1 --fixed_range_v4 10.0.1.0/24 
--num_networks 1 --network_size 256 --vlan 1 --project_id 
2e744c1a2032ccb1a0cdf7c5f825d046

The bridge and the vlan are not created immediately, do you have any 
idea if there is another daemon that needs to run or something so or 
some additional advice, my nova-network is a server different from the 
nova-compute.

Also i noticed that the ensure_bridge method from linux_net.py never is 
called, in this script there is the brctl addbr call to posix.

root at devlabnova:~# nova-manage  network list
id       IPv4                  IPv6               start address      
DNS1               DNS2               VlanID             project        
     uuid
20       10.0.1.0/24           None               10.0.1.3           
None               None               1                  
2e744c1a2032ccb1a0cdf7c5f825d046               
a667af77-8ffe-42f8-a094-c2ce71d59171

root at devlabnova:~# brctl show
bridge name    bridge id        STP enabled    interfaces


My nova.conf is as follows in terms of nova-network

##### nova-network #####
network_manager=nova.network.manager.VlanManager
public_interface=eth0
vlan_interface=eth1
network_host=devlabnova
fixed_range=10.0.0.0/8
network_size=1024
dhcpbridge_flagfile=/etc/nova/nova.conf
dhcpbridge=/usr/bin/nova-dhcpbridge
force_dhcp_release=True
fixed_ip_disassociate_timeout=30
my_ip=172.16.16.10

Thanks in advance!
