I was experiencing issues with OpenStack deployed with Networking OVN and just saw this message in my dmesg:
--- [ 12.241706] 8021q: adding VLAN 0 to HW filter on device eno2 [ 15.077293] eno2: Invalid MTU 9000 requested, hw max 68 --- And the IP of my eno2.600 VLAN is gone! So, the Instances can't ping each other because that is where my data path (GENEVE / VXLAN) tunnels are created on! How a bug like this ended up into an LTS release? :-( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1679823 Title: bond0: Invalid MTU 9000 requested, hw max 1500 with kernel 4.10 (or 4.8.0-49) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1679823/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
