The software described in this documentation is either no longer supported or is in extended support.
Oracle recommends that you upgrade to a current supported release.
To add a PXE client to be provisioned by Spacewalk:
List the Kickstart profiles in Spacewalk that are usable by Cobbler.
#
cobbler profile list
ol6u6-x86_64-devsys:1:SpacewalkDefaultOrganization ol6u6-x86_64-server:1:SpacewalkDefaultOrganizationUse the cobbler system add command to define the host name, MAC address, and IP address of the target PXE client and the profile that you want to install, for example:
#
cobbler system add --name=svr1.mydom.com --hostname=svr1.mydom.com --mac=08:00:27:c6:a1:16
\--ip=92.168.1.253 --profile=ol6u6-x86_64-server:1:SpacewalkDefaultOrganization
If you are provisioning a client that uses an IP address from a DHCP address pool, you might use a command such as the following:
#
cobbler system add --name=devsys2 --hostname=devsys2
\--profile=ol6u6-x86_64-devsys:1:SpacewalkDefaultOrganization
\--kopts="ksdevice=eth0"
The --kopts option allows you to specify options to be added to the kernel boot line. In this example,
ksdevice=eth0
specifies the network interface that Kickstart should use for installation, which prevents the installation pausing to prompt you to choose which network interface to use.In this example, the
ol6_desktop
profile would use a Kickstart configuration that installs a set of packages to configure a development system rather than a server system.By default, GRUB displays a boot menu for UEFI-based clients and prompts you to choose an entry. To prevent GRUB from displaying this menu, edit
/etc/cobbler/pxe/grubsystem.template
and adddefault=0
,hiddenmenu
, andtimeout=0
entries, for example:default=0 hiddenmenu timeout=0 title $profile_name root (nd) kernel $kernel_path $kernel_options initrd $initrd_path
Run cobbler sync.

/var/lib/tftpboot/pxelinux.cfg
and/var/lib/tftpboot/grub
. These files are named for the client's MAC address prefixed by01-
, which represents the ARP hardware type for Ethernet, and use dashes to separate each byte value instead of colons. These client-specific files are based on/etc/cobbler/pxe/pxesystem.template
and/etc/cobbler/pxe/grubsystem.template
.Cobbler also creates generic
pxelinux.cfg/default
andgrub/efidefault
boot configuration files from/etc/cobbler/pxe/pxeprofile.template
and/etc/cobbler/pxe/grubprofile.template
.Cobbler adds an entry for the client to
/etc/dhcp/dhcpd.conf
, which is based on/etc/cobbler/dhcp.template
, for example:# group for Cobbler DHCP tag: default group { host generic1 { hardware ethernet 08:00:27:c6:a1:16; fixed-address 192.168.1.253; option host-name "svr1.mydom.com"; if substring(vendorclass, 0, 9)="PXEClient" { if pxetype=00:06 or pxetype=00:07 { filename "/grub/grub.efi"; } else { filename "/pxelinux.0"; } } next-server swksvr.mydom.com; } }
Enter the cobbler system list command to display the PXE systems that are known to Cobbler.
