Hello , *I want to write a script to attach a '.iso' image to a vm * so ,can you please help me or tell me some api so that i can continue my work !!!

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 ========= ...

and got some exceptions
Connected to RHEVM Successful Failed to create VM with disk and NIC 'str' object has no attribute 'export' Failed to Start VM: 'NoneType' object has no attribute 'status'
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 !!

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