[ovs-dev] [PATCH 0/7] OVN load-balancers.

[Gurucharan Shetty]

This series adds support for load balancers in OVN.
One could create a load_balancer object on OVN with
a command of the form:
ovn-nbctl  create load_balancer \
vips:30.0.0.1="172.16.1.2,172.16.1.3,172.16.1.4"

One could also use L4 ports to create LBs.
e.g:
ovn-nbctl create load_balancer \
vips:'"30.0.0.1:8000"'='"172.16.1.2:80,172.16.1.3:80,172.16.1.4:80"'

And then attach the created load_balancer to any logical switch where
the client resides.

e.g.:
ovn-nbctl set logical_switch foo \
load_balancer=91facf32-d6f1-43e9-bead-54c59af493e1
