Netserver 7 RC3 / RC4 don't find ethernet interface

By starting the Install-ISO from USB i get the error:

[code]The following problem occured on line 0 of the kickstart file:

Unable to open input kickstart file: curl#37 - “Couldn’t open file /tmp/network-include”

Exception AttributeError: " ‘NoneType’ object has no attribute ‘udev_unref’ " in…

“ip link” don’t find any ethernet interface.

With the ArchLinux iso i get the ethernet interface and dhcpd works.

Probably the kernel doesn’t recognize your ethernet interface.
You should refer to RHEL manual:
