Public bug reported:
When I install openstack(queens) with kolla-ansible ,I open the neutron-dvr.
But, I find some VM with floating ip can not arrived. I tryed to ping the fip
and collect icmp packages with tcpdump. I find in qrouter namespace, the rfp
interface can get the packages. But the qr interface cannot get. I find there
is an DNAT rules in iptables rules.
Last, I find the centos kernel version is "CentOS Linux (3.10.0-862.el7.x86_64)
7 (Core)", but some other(can ping) is "CentOS Linux
(3.10.0-693.21.1.el7.x86_64) 7 (Core)". When I change kernel version to 693, it
works.
I don't know how the packages changes in kernel, so I try to get help here.
Thanks.
