Hi all,
During testing of Neutron upgrades, I have found that restarting the L3 agent in DVR mode is causing the VM network downtime for configured floating IP.
The lockdown is visible when pinging the VM from external network, 2-3 pings are lost.
The responsible place in code is:
DVR: destroy fip ns: fip-8223e12e-837b-49d4-9793-63603fccbc9f from (pid=156888) delete /opt/openstack/neutron/neutron/agent/l3/dvr_fip_ns.py:164

Can someone explain why the fip namespace is deleted? Can we workout the situation, when there is no downtime of VM access?
