Hi
Like many others, we had some problems with the order of the network cards during and after the installation. We found a way to workaround that problem, i'll try to explain how we did that:
- Device for Installation:
There are several points during installation where the network card is configured. There is a way to ensure that always the same card is used.
First, enable pxe only on the device you want to use for the installation.
After that, we tell the install kernel that we want to use the same device to fetch the kickstart.
/etc/cobbler/setting: ---------8<------------ kernel_options: ksdevice: bootif ---------8<------------
We change the value of ksdevice to bootif. bootif is a variable.
/etc/cobbler/pxesystem.template: ---------8<------------ default linux prompt 0 timeout 1 label linux kernel $kernel_path $append_line IPAPPEND 2 ---------8<------------
We add IPAPPEND 2 to the template file. This adds the bootif variable which contains the network device information to the append line.
Finally we need to ensure that anaconda uses the same device. Simply remove all network commands from your kickstart template/snippets and replace it with:
network --bootproto=dhcp
- Configure the network cards with the information from cobbler
We found that anaconda is not able to create the configuration of the network devices related to their MAC/hardware address. We decided to write a cheetah template, that uses the information form cobbler to write the network configuration directly to /etc/sysconfig/network-scripts/
/var/lib/cobbler/snippets/post_baremetal ---------8<------------ # Network information
#set $network_baremetal_file = '/etc/sysconfig/network' echo "NETWORKING=yes" > $network_baremetal_file echo "NETWORKING_IPV6=no" >> $network_baremetal_file
#for $n in $range(8, -1, -1) #set $ns = str($n) #if $getVar('mac_address_intf' + $ns, '') #set $network_baremetal_device = 'eth' + $ns #set $network_baremetal_mac = $getVar('mac_address_intf' + $ns, '') #set $network_baremetal_devfile = '/etc/sysconfig/network-scripts/ifcfg-' + $network_baremetal_device echo "DEVICE=$network_baremetal_device" > $network_baremetal_devfile echo "HWADDR=$network_baremetal_mac" >> $network_baremetal_devfile echo "ONBOOT=yes" >> $network_baremetal_devfile #if $getVar('ip_address_intf' + $ns, '') #if $getVar('ip_address_intf' + $ns, '') #set $network_baremetal_ip = $getVar('ip_address_intf' + $ns, '') echo "BOOTPROTO=static" >> $network_baremetal_devfile echo "IPADDR=$network_baremetal_ip" >> $network_baremetal_devfile #if $getVar('subnet_intf' + $ns, '') #set $network_baremetal_netmask = $getVar('subnet_intf' + $ns, '') echo "NETMASK=$network_baremetal_netmask" >> $network_baremetal_devfile #else echo "NETMASK=255.255.255.0" >> $network_baremetal_devfile #end if #if $getVar('gateway_intf' + $ns, '') #set $network_baremetal_gateway = $getVar('gateway_intf' + $ns, '') #set $network_baremetal_hostname = $getVar('hostname_intf' + $ns, 'not-found.example.com') echo "HOSTNAME=$network_baremetal_hostname" >> $network_baremetal_file echo "GATEWAY=$network_baremetal_gateway" >> $network_baremetal_file #end if #end if #else echo "BOOTPROTO=dhcp" >> $network_baremetal_devfile #end if #end if #end for ---------8<------------
We hope this helps someone else too.

We thought about adding that to the wiki. Which site would be the best place for that?

Towards the bottom of https://fedorahosted.org/cobbler/wiki/KickstartSnippets would be good for now.
We really need to develop that into more of a "useful kickstart tricks" cookbook over time.
