I have "issues" with later versions of Centos/RHEL 7 also.
PXE boot seems to work, but after the new kernel kexec's, it seems to drop the NICS and
further in the process for some reason, the nics never come up, which leads to all kindsof issues of course
(trying to boot a cluster that way). I also have the impression that it is a dracut issue, however, I have not pinpointed it yet.
