Environment:
cloud: bionic-ussuri
neutron-*: 2:16.1.0-0ubuntu2~cloud0
openvswitch-switch:2.13.0-0ubuntu1~cloud0
External FIPs assigned to VM with a distributed HA router.
Ping/ssh to VM works for ~10% of the time, 90% of the time packets are dropped.
When not working tcpdumping on the VM directly via virsh console can see the ICMP packets arriving and leaving for the source.
Tcpdumping at the same time on the qrouter namespace can see the packets coming from the VM and leaving for the source, but never reaching the source, resulting in timeouts. |
