[General]
On Azure, when provisioning a Hirsute VM with Accelerated Networking

[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 to debug, run:

In "/run/cloud-init/instance-data.json", I can see:

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
