Sorry, I haven't personally used this tool, but have faced this issue 
with our xCAT cluster.

I assume that your system is using pxelinux for booting the nodes.  You 
should be able to find files in a directory named (usually) 
/tftpboot/pxelinux.cfg these are named by MAC address.  At boot time, 
after the DHCP server has supplied the node with an IP address and the 
pxe kernel, the pxe code retrieves the config file corresponding to the 
node's MAC.  This file says where to find the linux kernel and specifies 
kernel options, for instance when booting the kickstart installer one of 
these files looks like this one our cluster:

-bash-2.05b$ cat /tftpboot/pxelinux.cfg/0A0000DD
#install sl304-x86-compute-compute
SERIAL 0 9600
DEFAULT xCAT
LABEL xCAT
KERNEL xcat/sl304/x86/installz
APPEND utf8 root=/dev/ram nofb nomce console=tty1 console=ttyS0,9600 
ks=nfs:cap-eth0:/xcatinstaller/scripts/sl304/x86/compute-compute 
ksdevice=eth0 initrd=xcat/sl304/x86/install.gz

Anyways, you can see that the ksdevice is specifed in there.  Now, xCAT 
produces this file from a template, so it is fairly easy to modify.  You 
can choose how to get this option in to the pxelinux.cfg file for your 
system.

Hope this helps (or at least isn't completely off-base).

Cheers,
Tom
