This problem still bites us. I've tried to play around with DHCP
settings (rd.net.timeout.dhcp, rd.net.dhcp.retry) to no avail.
I'm happy about /any/ hint.
Cheers

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
