Dear Sir,
We are testing in OpenStack (Stein) + OpenDaylight (Neon) + Open vSwitch
(v2.11.1). It's an all-in-one virtual deployment (OPNFV-9.0.0).
The instances can ping each other on the same compute node,
but cannot ping each other if instances are on different compute nodes.
vm1 ping vm2 show *Destination Host unreachable.*
Compute nodes can ping each other.
