I isolated the issue between those two serial: 20210219 (doesn't have the issue) and 20210220 (reproduces the issue).
The main difference I can see between those two serial is systemd version: 20210219 -> 247.1-4ubuntu1 20210220 -> 247.3-1ubuntu2 Cloud-init version is the same (20.4.1-79-g71564dce-0ubuntu1). I will try to get a better package diff between those two images to understand if anything else significant changed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1919177 Title: Azure: issues with accelerated networking on Hirsute To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1919177/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
