[RFE] Physical network awareness

[Mark Goddard]

Ironic added support for physical network awareness [1] in the pike release. With multiple physical networks it is possible that each physical network extends over a subset of the devices in a network. Further, the segmentation ID space on different physical networks may overlap.

This RFE proposes to support configuration of a set of physical networks on each switch. On neutron network creation and deletion, NGS will only (de)provision VLANs on devices tagged with that network's physical network. If a device is not tagged with any physical networks, the old behaviour of provisioning all networks on all devices is used.

Configuration of physical networks will be via a new per-device config option, ngs_physical_networks:

[genericswitch:switch1]
device_type = acme
ip = 1.2.3.4
username = bob
password = drowssap
ngs_physical_networks = physnet1,physnet2

    Add physical network awareness

    Ironic added support for physical network awareness [1] in the pike
    release. With multiple physical networks it is possible that each
    physical network extends over a subset of the devices in a network.
    Further, the segmentation ID space on different physical networks may
    overlap.

    This change adds support for configuration of a set of physical networks
    on each switch. On neutron network creation and deletion, NGS will only
    (de)provision VLANs on devices tagged with that network's physical
    network. If a device is not tagged with any physical networks, the old
    behaviour of provisioning all networks on all devices is used.

    Configuration of physical networks is be via a new per-device config
    option, ngs_physical_networks:

    [genericswitch:switch1]
    device_type = acme
    ip = 1.2.3.4
    username = bob
    password = drowssap
    ngs_physical_networks = physnet1,physnet2
