fyi same source version ergo same 'cloud daemon inactive (dead)' + 'network down eth0' sub issues in slipstreamed photon-4.0-bff8291af.iso vhd'ified to Azure.

It requires at least one interface to be up and a ipv4 address to communicate with the meta data server. Note it does not configure the primary address. Hence it will not work. #22 should drop the too much backtrace

I just tested with latest commit. It will keep on running

I will give feedback as soon as the Ph4 repo contains the latest commits. 'cloud daemon inactive (dead)' is a strange issue (?) Yes, in a temporarily 'all network path down with reboot' scenario, [#20,#22] help ensure active cloud-network.service .

It will take a while. I have add IPv6 support which is pending for a while now

Failed to fetch instance metadata: 'Get "http://127.0.0.1:5209/api/cloud/network": dial tcp 127.0.0.1:5209: connect: connection refused ```

Is cloud-network-setup is running in azure cloud machine? what is the status of 

``` sudo systemctl status cloud-network.service```

If you clone and install from github does it run correctly ?

case distinction
In a metadata server all paths down constellation WITH reboot, the cloud-network.service fails to start.

Right after the installation, it remains "dead". Manual restart and it works.

In this constellation with a reboot, the daemon still works successfully.

git clone from repo, build and start /usr/bin/cloud-network works successfully.

tdnf install cloud-network-setup does not implicitly start the daemon. It needs a daemon restart to make the daemon run.

strange the same code works after reboot

It's unable to detect the cloud environment in first go . We need to update a version same as upstream.

fyi it's a different environment, one on ph5beta-on-ESXi and one on ph4rev2-on-Azure. Tested with slightly different cloud-network-setup versions. It would be nice to solve the issue for the ph4rev2-on-Azure environment.

In a non-privileged user account context, the install process seems to finish successfully the daemon configuration but the activation remains as issue. cloud-network-setup_issue19_4.txt
ExecStart with ambient process capabilities might be worth to have a look at it ? -> more tdnf debug information

Activation. Well cloud-network-setup only runs in cloud environment. yes to start the daemon privileged user is required

Solves it! Please add carriage return+line feed.

Tested on ph4rev2-on-Azure

With e.g. networkctl down eth0 as test case start, cnctl still exits with a non-user friendly message.
