[Bug 1843221] [NEW] manage_resolv_conf not working in ubuntu18.04 cloud images

 

Public bug reported:

I'm using the following stanza in my cloud-init VM configurations:

manage_resolv_conf: true
resolv_conf:
  nameservers:
  - 8.8.8.8
  - 8.8.4.4

However, neither /etc/resolv.conf not 'systemd-resolv --status' reflects
it. In both cases, DNS is delegated to the virtualisation host.

The virtualisation host is:

paag@pavilion:~/virt/images$ uname -a
Linux pavilion 4.15.0-60-generic #67-Ubuntu SMP Thu Aug 22 16:55:30 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
paag@pavilion:~/virt/images$ virsh --version
4.0.0

I'm creating the VMs directly with virsh.
