The "vlan-aware-vms" feature allows Nova users to launch VMs on a single
|
|
port (trunk parent port) that connects multiple Neutron logical networks
|
|
together.
|
|
features:
|
|
- The feature "vlan-aware-vms" is available. To enable it, a service plugin
|
|
named 'trunk' must be added to the option ``service_plugins`` in your
|
|
neutron.conf. The plugin exposes two new extensions ``trunk`` and
|
|
``trunk_details``. The plugin can work with multiple backends and in
|
|
particular Neutron has support for `ML2/openvswitch <https://docs.openstack.org/neutron/latest/contributor/internals/openvswitch_agent.html#tackling-the-network-trunking-use-case>`_
|
|
and ML2/linuxbridge.
|
|
Even though Neutron API compatibility should be preserved for ports
|
|
associated to trunks, since this is the first release where the feature
|
|
is available, it is reasonable to expect possible functionality gaps for
|
|
one or both drivers. These will be filled over time as being reported.
|
|
The CLI is available via openstackclient, and python-neutronclient 5.1.0
|
|
or above. For more details, please check the networking guide.
|
|
security:
|
|
- |
|
|
When working with the ML2/openvswitch driver, the "vlan-aware-vms" feature
|
|
has the following limitations:
|
|
|
|
* security groups do not work in conjunction with the iptables-based
|
|
firewall driver.
|
|
* if security groups are desired, the use of the stateful OVS firewall is
|
|
required, however that prevents the use of the DPDK datapath for OVS
|
|
versions 2.5 or lower.
