@rhtyd I would like to stress that this issue also occurs on Ubuntu 18.04 systems and not only on 20.04 as @weizhouapache mentioned in the original commit. Two Ubuntu 18.04 systems running with VXLAN: <pre> root@hv-138-e14-33:~# bridge -o link show | grep vxlan500 28: vxlan500 state UNKNOWN : <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master brvx-500 state forwarding priority 32 cost 100 </pre> <pre> root@hv-138-e14-25:~# bridge -o link show | grep vxlan500 9: vxlan500: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master brvx-500 state forwarding priority 32 cost 100 </pre> I checked their kernels: <pre> Linux hv-138-e14-33.ams02.cldin.net 5.4.0-60-generic Linux hv-138-e14-25.ams02.cldin.net 5.4.0-66-generic Distributor ID: Ubuntu Description: Ubuntu 18.04.5 LTS Release: 18.04 Codename: bionic </pre> This causes Instance to **loose** their network connectivity after a initial boot or migration. A very small fix which prevents major issues for (end-)users. I would urge to merge this in 4.13 and then 4.14 so that we can release 4.14.2 with this fix in there. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
