@raharper could you give the systemd in this ppa a test: https://launchpad.net/~ddstreet/+archive/ubuntu/systemd
also, you're setting the MTUBytes via .link file, but that won't work inside an lxd container as that setting only has any effect during udev processing of interface 'add' uevent, which doesn't happen inside an lxd container because 1) the interface already exists when the container boots up and 2) systemd-udev-trigger.service has no effect (unlike bare metal systems or vms) because unprivileged containers can't force uevent generation by writing to sysfs uevent nodes. Instead try adding a [Link] section to the .network file with the MTUBytes; that will get applied every time networkd starts. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1671951 Title: networkd should allow configuring IPV6 MTU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1671951/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
