Hi, 

I setup the host+engine on centos 7 on my home network and everything worked perfectly, However when I connected it to my work network networking failed completely.

hostname -I would be blank.
lspci does list the hardware
nmcli d is empty
nmcli con show is empty
nmcli device status is empty

there is a device in /sys/class/net/

Is there a way to fix this? or do I have to reinstall?

On another note, ovirt is amazing!

Thanks for the quality product,
Rulasmur
