(vxlan, 3 controllers, 2 compute)

Steps:
1) Create net, subnet
2) Create DVR router with gateway to external net
3) Connect router and new net
4) Boot vm with floating
5) Find compute with vm
6) Stop l3 agents on this compute: service neutron-l3-agent stop
7) Wait some minutes
8) Start l3 agent: service neutron-l3-agent start
9) Wait some time
9) Check ping 8.8.8.8 from vm
