Hi
Sorry for late reply.
Ryu will collect host information when there is a packet in sent to
controller.
There should be at least one Arp, IPv4 or IPv6 packet send by host and
packet in to controller.
Please check:
1. Default action of table miss, should be packet in.
2. Try use "pingall" command from topology, let host send some packet to
network.
