features:
|
|
- Add flannel's host-gw backend option. Magnum deploys cluster over a
|
|
dedicated neutron private network by using flannel. Flannel's host-gw
|
|
backend gives the best performance in this topopolgy (private layer2) since
|
|
there is no packet processing overhead, no reduction to MTU, scales to many
|
|
hosts as well as the alternatives. The label "flannel_use_vxlan" was
|
|
repurposed when the network driver is flannel. First, rename the label
|
|
flannel_use_vxlan to flannel_backend. Second, redefine the value of this
|
|
label from "yes/no" to "udp/vxlan/host-gw".
