openstack mitaka on VM, can not ping floatingip of inner guest VM

Hi all,

I have one CentOS 7 VM and installed Openstack Mitaka ready

I used OVS and create two networks, one is public network and the other is internal network

I upload cirros image for some simple test

I deployed one guest vm from cirros image and associate floatingip

Then I logined to host and try to ping this new VM floating ip, but failed

I checked security group and found I did set for icmp and tcp

I did know most openstack installed on physical host

But we are in CI test, so use VM to install openstack run some tempest

Could anyone support me to fix this problem? I searched in web and found many solution, but not work.

Below is some info for our env.

host ip: public network:, floatingip range: internal network:

guest VM ip:, floatingip:

router ip:, gateway:

  1. I logined to and ping failed
  2. ip netns list ... qrouter-375934b5-ad4d-4474-9aa6-f127d809a43b

  3. from router, try to ping guest vm ip netns exec qrouter-375934b5-ad4d-4474-9aa6-f127d809a43b ping -c 4 PING ( 56(84) bytes of data. 64 bytes from icmp_seq=1 ttl=64 time=2.37 ms 64 bytes from icmp_seq=2 ttl=64 time=0.584 ms 64 bytes from icmp_seq=3 ttl=64 time=0.584 ms 64 bytes from icmp_seq=4 ttl=64 time=0.526 ms
