If you are using XC, then the "New VM Wizard" (doubleclick) seems to
remove the boot options, yes.
But you can use the "quick create", and then the ks boot options
still remains.

These commands will quickly generate a template with "quick create"
enabled:
(only the last two commands differs from Grants tutorials)

NETUUID=$(xe network-list bridge=xenbr0 --minimal)
TMPLUUID=$(xe template-list | grep -B1 'name-label.*Red Hat.* 6.*64-bit' 
| awk -F: '/uuid/{print $2}'| tr -d " ")
VMUUID=$(xe vm-install new-name-label="CentOS6-64bit" template=${TMPLUUID})
xe vif-create vm-uuid=$VMUUID network-uuid=$NETUUID mac=random device=0
xe vm-param-set uuid=$VMUUID 
other-config:install-repository=http://mirror.centos.org/centos/6/os/x86_64
xe vm-param-set uuid=$VMUUID 
PV-args="ks=http://grantmcwilliams.com/files/kickstart-minimal6-x86_64.cfg 
ksdevice=eth0"
xe vm-param-set uuid=${VMUUID} other-config:disable_pv_vnc=1 
other-config:instant=true
xe vm-param-set uuid=${VMUUID} is-a-template=true


Or you could do the same from within XC:
- create a vm from the standard template, add install from url
  and add boot params "ks=... ksdevice=..."
- uncheck "Start the new VM automatically" on the last wizard page
- convert the vm to template


Then create a new VM from the template by right-clicking the new
template and select "Quick Create"

(Tested in XC 6.1, don't know if this works in older versions)
