@gjolly There were networking-related changes in systemd which could have caused this but I also see that the kernel packages also changed between the Azure images: -ii linux-image-azure 5.8.0.1017.19+21.04.14 ... +ii linux-image-5.8.0-1022-azure 5.8.0-1022.24+21.04.2
Could you please prepare an image that has the older kernel and newer systemd to rule out kernel changes causing the issue? Also do you still observe the issue in Impish? It has systemd 248 now. ** Changed in: systemd (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-azure in Ubuntu. https://bugs.launchpad.net/bugs/1919177 Title: Azure: issues with accelerated networking on Hirsute Status in cloud-init: Incomplete Status in cloud-init package in Ubuntu: Incomplete Status in linux-azure package in Ubuntu: New Status in systemd package in Ubuntu: Incomplete Bug description: [General] On Azure, when provisioning a Hirsute VM with Accelerated Networking enabled, sometimes part of the cloud-init configuration is not applied. Especially, in those cases, the public SSH key is not setup properly. [how to reproduce] Start a VM with AN enabled: ``` az vm create --name "$VM_NAME --resource-group "$GROUP" --location "UK South" --image 'Canonical:0001-com-ubuntu-server-hirsute-daily:21_04-daily-gen2:latest' --size Standard_F8s_v2 --admin-username ubuntu --ssh-key-value "$SSH_KEY" --accelerated-networking ``` After a moment, try to SSH: if you succeed, delete and recreate a new VM. [troubleshooting] To be able to connect into the VM, run: az vm run-command invoke -g "$GROUP" -n "$VM_NAME" --command-id RunShellScript --scripts "sudo -u ubuntu ssh-import-id $LP_USERNAME" ``` In "/run/cloud-init/instance-data.json", I can see: ``` "publicKeys": [ { "keyData": "<my-pub-key>", "path": "/home/ubuntu/.ssh/authorized_keys" } ], ``` as expected. [workaround] As mentioned, Azure allows the user to run command into the VM without SSH connection. To do so, one can use the Azure CLI: az vm run-command invoke -g "$GROUP" -n "$VM_NAME" --command-id RunShellScript --scripts "sudo -u ubuntu ssh-import-id $LP_USERNAME" This example uses "ssh-import-id" but it's also possible to just echo a given public key into /home/ubuntu/.ssh/authorized_keys NOTE: this will only solves the SSH issue, I do not know if this bug affects other things. If so the user would have to apply those things manually.
