[Spacewalk-list] PRE Section doesn't work at all KVM Guest

[William H. ten Bensel]

Hopefully this example will help.   You should be able to configure your 
hostname logic like the following:

We had to do the following with CentOS 7.2 and Oracle Linux 7.2, because 
there is a bug with how the static --network line is being generated. (Bug 
opened with support and they have confirmed). 

Systems -> Kickstarts -> Profiles -> {profile} -> Kickstart Details -> 
Advanced Options -> Custom Options:
        %include /tmp/network.out

Systems -> Kickstarts -> Profiles -> {profile} -> Scripts:

Name: Static_BUG 
$SNIPPET('spacewalk/1/72network_bug')
Pre-Script
Check template --> Do not forget this, or it will not work. 


%pre --log /tmp/ks-pre.log.1
# BEGIN: network Snippet
# Issue with CentOS 7.2, not able to handle just network --bootproto 
static

# Get the static information that was passed during anaconda.
cat /proc/cmdline > /tmp/cmdline.out

server_ip=`awk -F"ip=" '{print $2}' /tmp/cmdline.out |awk '{print $1}'|awk 
-F":" '{print $1}'`
server_gw=`awk -F"ip=" '{print $2}' /tmp/cmdline.out |awk '{print $1}'|awk 
-F":" '{print $3}'`
server_nm=`awk -F"ip=" '{print $2}' /tmp/cmdline.out |awk '{print $1}'|awk 
-F":" '{print $4}'`
server_host=`awk -F"ip=" '{print $2}' /tmp/cmdline.out |awk '{print 
$1}'|awk -F":" '{print $5}'`
server_dns=`awk -F"nameserver=" '{print $2}' /tmp/cmdline.out |awk '{print 
$1}'`

if [[ -n "$server_host" ]]; then
cat <<_EOF >/tmp/network.out

network --noipv6 --onboot=yes --bootproto static --ip=$server_ip 
--netmask=$server_nm --gateway=$server_gw --nameserver=$server_dns 
--hostname=$server_host --device=link --activate
_EOF

# Another snippet will handle hostname, /etc/hostname, /etc/hosts, 
/etc/sysconfig/network, and/or
# /etc/sysconfig/network-scripts/ifcfg-* if it is not passed here. 
# That script most come prior to Registration and Activation!!
else
cat <<_EOF >/tmp/network.out


network --noipv6 --onboot=yes --bootproto static --ip=$server_ip 
--netmask=$server_nm --gateway=$server_gw --nameserver=$server_dns 
--device=link --activate
_EOF

fi

# END: network Snippet




- Thanks and good luck

After installation there's no file pre_install_network_config in tmp 
directory..

May be nochroot can help?

Are you including that file?

The following will need to be in your kickstart...
%include /tmp/pre_install_network_config

Stuck on this problem - I wanted to set up hostname for KVM machine on 
pre,

ok - I spent 3 days, but in fact ks ignore all pre sections...

also I found that Spacewalk trying to set hostname by itself, here the 
text from anakonda.cfg

# Start of code to match cobbler system interfaces to physical interfaces 
by their mac addresses
#  Start eth0
# Configuring eth0 (00:16:3e:53:0e:0d)
if mac_exists 00:16:3e:53:0e:0d
then
  get_ifname 00:16:3e:53:0e:0d
  echo "network --device=$IFNAME --bootproto=dhcp --hostname=virttest001" 
>> /tmp/pre_install_network_config
fi

But no logs, no errors, no other stuff. Also no my pre scripts in /tmp 
directory 


Any thoughts?
