Hi,
kickstarting fails due to problems with host resolution, even though the network seems to be properly configured through DHCP. eno1 and eno2 are both attached to the network, but only eno1 gets an IP via DHCP. Still `curl` cannot resolve the mirror host and the kickstart host during dracut-initqueue:

dropped to the emergency shell, the network config looks absolutely ok:
$ ip route default via 10.128.196.97 dev eno1 10.128.196.0/24 dev eno1 proto kernel scope link src 10.128.196.20 169.254.95.0/24 dev enp0s20u1u5 proto kernel scope link src 169.254.95.120 $
`ip a` shows the correct IP address for eno1 and /etc/resolv.conf has all required nameservers. From the emergency shell both hostnames (our.centos.mirror and our.kickstart.server) are perfectly resolvable and accessible.
The used PXE config is:
LABEL CentOS-7 kernel centos-7.2/vmlinuz append initrd=centos-7.2/initrd.img ip=dhcp inst.repo=http://our.centos.mirror/7.2.1511/os/x86_64 inst.ks.sendmac inst.ks=http://our.kickstart.server/ks.cgi
Any idea, why curl cannot resolve the two hostnames or how I can debug this further?
Cheers frank
