Quote from an actual installation:

[root at xenh4 ~]# history| grep virt
virt-install  -n dhcpdns -p -r 1024 --os-type=linux --vnc -f 
/var/lib/xen/images/dhcpdns -s 2 -l

"ks=ftp://192.168.50.40/linux/ks-minimalC6-xen.cfg"

[root at xenh4 ~]# uname -a
Linux xenh4 2.6.18-400.1.1.el5xen #1 SMP Thu Dec 18 02:18:37 EST 2014 
i686 i686 i386 GNU/Linux

https://github.com/CentOS/Community-Kickstarts/blob/master/ks-minimalC6.cfg 
is quite close to the above mentioned ks-minimalC6-xen.cfg ( actually 
both are descendants of the same template of mine )
