[libvirt] Need Help To Destroy Virtual Machines

Hello...! I am using libvirt-php for controlling my xen virtual machines. For this I have installed libvirt-php along with xampp server. Now I need to create a web based controll panel application which shows me running vms, and some options like Shutdown, Pause, Create, Destroy. My aim is, when I click Destroy button the selected vm should be destroyed. For this I have used the following php-script: <?php $conn=libvirt_connect("xen:///"); $name=libvirt_domain_lookup_by_id($conn,4); // Here '4' is the id of my running vm $dest=libvirt_domain_destroy($name); echo $dest; ?> When I execute this it shows me following warning: Warning: libvirt_domain_destroy() [function.libvirt-domain-destroy]: operation virDomainDestroy forbidden for read only access in /opt/lampp/htdocs/xampp/xen/test.php on line 5 So, Could you please help me to solve this? ! Thank You !
