OpenStack Rocky : Configure Neutron#5 (Compute Node)2019/08/20 |
|
Configure OpenStack Network Service (Neutron).
This example is not All in One Settings like here,
but Configure the 3 Nodes environment like follows. Neutron needs a plugin software,
it's possible to choose it from some softwares. This example chooses ML2 plugin. ( it uses Open vSwitch under the backend )
