Description of problem: When installing RHEL-7 all network interfaces are checked, which is OK but the way this is done is rather hopeless. I takes 2 minutes to detect that there is no cable connected to a network interface and moreover interfaces are checked one after another so with several NICs installed one can easily get very frustrated. Once the system is installed, the problem goes away. Version-Release number of selected component (if applicable): Any recent RHEL-7 compose. The last one I tried was RHEL-7.0-20131111.n.0 but I saw it on older composes, too. How reproducible: 100% Steps to Reproduce: 1. put several NICs into a computer but connect only one of them 2. boot from RHEL-7 install media (I used PXE) Actual results: Boot process is stuck for several minutes while trying to get IP addresses on unconnected NICs. Expected results: All NICs should be checked in parallel and/or unconnected ones should be just skipped. Additional info:
NIC's are checked by dracut.
Please test http://people.redhat.com/harald/downloads/dracut/dracut-033-67.el7/ if possible
Verified with dracut mentioned in c#2. Boot process is slightly faster because dhclient isn't run on inactive (i.e. no carrier) network interfaces. However this is as much as we can get from the current situation when the carrier presence is checked by a shell script after some waiting for the link to come up. In the current situation (without NetworkManager in dracut) it is not possible to speed this process up any more as we need to wait for the link state to settle because there might be some hardware on the other side of the cable that is slower with putting the link up.
Re-tested it also on the newest compose RHEL-7.0-20140314.0 with dracut-033-147.el7 and it works as well.
