Hello Netbulae,

Thanks for your report. Toni, can you please share your thoughts here? It seems the issue I have reported days ago right?

Toni, to be clear, based on the log seems BZ#1104035.

>  os.unlink(fileToRemove)
>      OSError: [Errno 16] Device or resource busy:       '/etc/sysconfig/network-> scripts/ifcfg-eth0'

You're right Douglas. That bug happens here. Also https://bugzilla.redhat.com/1108571 is related.
