## Troubleshooting
If following the above steps hasn't quite worked, please review this section for well known issues.

### Console doesn't come up
In case of libvirt there is no wildcard DNS resolution and console depends on the route which is created by auth operator ([Issue #1007](https://github.com/openshift/installer/issues/1007)).
To make it work we need to first create the manifests and edit the `domain` for ingress config, before directly creating the cluster.

- Add another domain entry in the openshift.conf which used by dnsmasq.
Here `tt.testing` is the domain which I choose when running the installer.
Here the IP in the address belong to one of the worker node.
```console
$ cat /etc/NetworkManager/dnsmasq.d/openshift.conf
server=/tt.testing/192.168.126.1
address=/.apps.tt.testing/192.168.126.51
```

- Make sure you restart the NetworkManager after change in the openshift.conf
```console
$ sudo systemctl restart NetworkManager
```

- Create the manifests
```console
$ openshift-install --dir $INSTALL_DIR create manifests
```

- Domain entry for cluster-ingress-02-config.yml file should be following (here domain is what your created initially)
```console
$ grep domain $INSTALL_DIR/manifests/cluster-ingress-02-config.yml

@praveenkumar Wouldn't you agree that my sed suggestion would better since folks can just directly copy&paste it?

domain: apps.tt.testing
```

- Start the installer to create the cluster
```console
$ openshift-install --dir $INSTALL_DIR create cluster
```
