Hi,<br>I tried to use the contextualization in the template file. But everytime I create the instance, it fails at boot time saying "tap device could not be connected". I belive this is the problem with xen. Is there any way I can change the driver of the iso file created by the opennebula when the instance is created. Following is the instance log<br>

<br>
Contextualization must be used in order to be able to assign the desired<br>
IP to the virtual machine. The contextualization script reads the MAC of<br>
the VM(opennebula assigns the MAC you have specified) and based on the MAC<br>
fields it assigns an IP. The script must be places inside your virtual<br>
machine.<br>
