Hi there, For whether or not the issue affects Groovy. I've been creating Groovy VMs on a loop to confirm if I could reproduce it there and (after ~50 tries) I still haven't seen it happen. I think we can safely assume that this issue does not affect Groovy.
Also I was able to reproduce the issue with gen1 hyper-v (before I was only using gen2). To continue the system log investigation, I can add the following: GOOD Apr 19 08:53:43 hirsute-man-2 systemd[1]: Finished Wait for Network to be Configured.

This is "obvious" considering the error raised by cloud-init but I just wanted to underline it. -- 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
