[one-users] Support for custom Xen drivers for disk images

[Ruben S. Montero]

Hi all,

This refers to http://dev.opennebula.org/issues/348.

There is a new DRIVER attribute for DISK. The DRIVER can be used to specify
custom drivers for images. Example

DISK = [ driver = "tap2:aio:", source="path_to_image", target="hda1"]

So it gets transformed to:
disk = [
    'tap2:aio:path_to_image,sda1,w',
]

This attribute is also supported by the image repository. So you can add
driver="file:" to an image template, or add it to an existing one using
oneimage update. Also you can specify it in the VM template as:

DISK = [ image="myimage", driver="file:"]

The DRIVER is also supported by CONTEXT devices just added as:

CONTEXT = [ driver = "file:" ,... ]

Finally, the driver defaults to "tap:aio:" you can change the default for
all the images including context in
$ONE_LOCATION/etc/vmm_ssh/vmm_ssh_xen.conf

Any feedback is more than welcome!

Cheers

Ruben
