<br>
Thanks for the reply but unfortunately it will not solve our
problem. Yes, if I define the <strong>DEV_PREFIX </strong>
parameter in the template using the Sunstone GUI then everything
works fine. But how do I do it for the OCCI self-service
individual templates? Also, if I define it as a default value then
I'm not sure our Windows images will work. We supply Windows 7, 8
& Server 2008 R2 images and well as Debian in the
self-service. Virtio is not by default built into Windows images.<br>
<br>
The reason we want to use the virtio drivers is that sometimes
delays in the underlying NFS infrastructure may cause SCSI
timeouts in Debian images. It doesn't cause any real problems but
it is disconcerting to our users. We hope that using the virtio
drivers will be more forgiving.<br>
<br>
Regards,<br>

<pre wrap=""> Hi,
How do you get the OCCI self-services templates to make an existing
system disk use the virtio drivers? If I put an entry in the template for
DISK it tries to create a second data disk, even when I explicitly try to
set the DISK_ID to 0 (see OOCI template and resulting template from
Sunstone below).

You can define that parameter in the image template and the virtual machine
disk will use it.

Also you can define default paremeters for kvm in the driver configuration
file.
