Hi guys.

It might Centos's repo/packages related - I'm not sure how this worsk - so, where to send/file a bug report with issue like this:
 ...
[ INFO  ] ok: [localhost]
[ INFO  ] TASK [ovirt.ovirt.engine_setup : Install oVirt Engine package]
[ ERROR ] fatal: [localhost -> 192.168.1.90]: FAILED! => {"changed": false, "msg": "Failed to download metadata for repo 'centos-ceph-pacific': Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve host name for http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=storage-ceph-pacific [Could not resolve host: mirrorlist.centos.org]", "rc": 1, "results": []}
[ INFO  ] TASK [ovirt.ovirt.hosted_engine_setup : Sync on engine machine]
...

thanks, L.
