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

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?
