RHEL 7 under VMWare Workstation 10: Problem with Network

Latest response

I have installed RHEL 7 as minimal installation under VMWare Workstation 10.

I cannot configure any network devices. The kernel doesn't find any.

I have tried open-vmware-tools, which comes with RHEL7 and also tested the VMWare tools which come with VMWare Workstation 10.
No difference.

Does anybody have a hint for me?
