Hi all,

I have installed openstack Liberty on 2 servers for 3 months. Couple of days, I have seen an issue that network to instances is not stable. When ssh to instanaces or ping to these, the packets or connection lost.

I tried to restart 2 hosts or neutron network but cannot solve the problem. Sometime it is ok, sometime it is not ok.
