Hi Eric,
Actually i am following your guide/pdf based on page 17 and after the
vlans were created as example you type the ip addr and brctl show to
make sure the bridges and vlans have been created, i guess it just
applies to the admin tenant, is it right? because i noticed that if i
add in --project_id the id of the Admin Tenant the bridge and vlan is
created immediately but if I add another project id it is not created.
Thanks in advance,
Omar L.

Omar,
After you have configured all your networks/vlans with nova-manage
network create, no vlan interfaces and no bridges will be created on
the nova-network node and the nova-compute nodes. The first vlan
interface and bridge will only be created the first time you boot an
instance for a given tenant.
If you boot for the first time an instance for a given tenant:
- a free network/vlan will be attributed to that tenant and this for ever;
- a vlan interface with a bridge and a dhcp connected on it will be
created on the nova-network node;
- a vlan interface with a bridge connected on it will be created on
the nova-compute node which has been chosen to run the instance.

Thanks Nathanael, so the bridges and vlans are created until the
instance is created?, because my understanding was that the
interfaces were created once the network create is applied, and the
interface appears in nova-network node and nova-compute node, is it
right?

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 http://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.

Omar,
The vlan tagged interfaces and bridges are created on the fly as
needed as users within the relevant projects start instances that
are scheduled to the relevant compute nodes.
