if i remove this cdroms = 'CentOS-6.2-x86_64-LiveCD.iso ' the code will
works fine and it will create a vm with blank template w/o any '.iso'
attached !!

Hi Romil,
In general you can use api guide [1] for this, anyway here is example:
1. create vm
============
...
2. insert cdrom
===============
vm = api.vms.get(name="myvm")
cdrom = vm.cdroms.get(id="00000000-0000-0000-0000-000000000000")
isofile = params.File(id="myiso.iso")
cdrom.set_file(isofile)
cdrom.update()
3. change boot order (to boot from cdrom and then from hd)
==========================================================
os=params.OperatingSystem(boot=[params.Boot(dev='cdrom'),
params.Boot(dev='hd')], ...)
api.vms.add(params.VM(name='myvm2',
os=os,
cluster=api.clusters.get('mycluster'),
template=api.templates.get('mytemplate')))
4. run vm
=========
...

use this ^ example for #1, or update boot order using same semantics
on existent vm.
