I have a Kubernetes VM and an unrelated VM on the same host in a cluster using an ovs-bridge. I'm able to ping between the two VMs but when I try to ping from a kubernetes container it fails. Using tcpdump on the ovs-bridge interfaces I can see ping and response on the unrelated VM's interface but only the outbound pings on the Kubernetes VM's interface. For some reason traffic is not routed back into the Kubernetes VM when it originates from a container. I suspect this might be due to Kubernetes containers using their own subnet (192.168.26.0/24 in this case). Has anyone run into this before?
