We are using the nocloud datasource to bootstrap VMs into ganeti via https://github.com/neicnordic/ganeti-os-nocloud but in the past few weeks, network on new VMs has been broken.
In `/var/lib/cloud/seed/nocloud/network-config` I have, for example:
```
version: 2
ethernets:
eth0:
match: {macaddress: 'aa:00:00:45:6a:15'}
addresses:
- '10.20.12.9/16'
gateway4: '10.20.0.1'
nameservers:
addresses:
- '10.22.1.1'
```
When the instance bootstraps, I see this error in `/var/log/cloud-init-output.log`:
```
Cloud-init v. 22.2-0ubuntu1~20.04.2 running 'init-local' at Thu, 23 Jun 2022 17:29:24 +0000. Up 9.69 seconds.
