[Xen-API] Creating a VM from a record

[mftahy <mofta7y@xxxxxxxxx>]

Hi


I am trying to use Zend XmlRbc to create a VM using a record.

I am particularly using this method

(VM ref) create (session_id s, VM record args)


the way I am trying to do it is the follwing

1- start a vm

2- get the current vm record using VM.get_record

3- shutdown the vm

4- create the VM using the the record we have from step 2 using the 
method VM.create(session_id s, VM record args)

this does not work !!


this is the error that returns by XMLRBC

Array
(
   [Status] => Failure
   [ErrorDescription] => Array
       (
           [0] => INTERNAL_ERROR
           [1] => 'list' object has no attribute 'items'
       )

)

and this is the output of xend.log

ERROR (xmlrpclib2:166) Internal error handling VM.create

create_domain
   raise XendError(str(e))
XendError: 'str' object has no attribute 'items'

every thing else is working OK except this call


and this is my xen version

xen_major              : 4
xen_minor              : 0
xen_extra              : .0_21091_06-0.1
xen_caps               : xen-3.0-x86_64 xen-3.0-x86_32p


what I am doing wrong here


example code that doesn't work

include_once "Zend/XmlRpc/Client.php";

       $client = new Zend_XmlRpc_Client('http://localhost:9363/');
       $client->setSkipSystemLookup(true);
       $service = $client->getProxy();
       $result = $service->session->login_with_password($username, 
$password);
$session = $result['Value'];

$result= $this->service->VM->get_record($session,VMID);

$record = $result['Value'];

$this->service->VM->create($session,$record);



thanks
