Image build FAILED with error: No disk activity in 300 seconds, failing.

Hi

I have tried to create a docker image by imagefactory.

When boot into kickstart installer, NIC waited too long time to download the installer LiveOS.

Network waited to be active at Starting dracut initqueue hook：

Starting dracut initqueue hook ...
8021q: adding VLAN 0 to HW filter on device eth0
dracut-initqueue RTNETLINK answers: File exists

Before NIC actived to download the installer image, imagefactory was exited with :
