Hi,
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

I have only used the file: driver . With :tap:aio, I get the above error.
Please advice.
