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.<br>
<br>
If you boot for the first time an instance for a given tenant:<br>
<br>
- a free network/vlan will be attributed to that tenant and this for
ever;<br>
- a vlan interface with a bridge and a dhcp connected on it will be
created on the nova-network node;<br>
- 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.<br>

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?<br>

<p>Omar,</p>
<p>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.</p>
