Hi,
I also face this issue on an Ubuntu 10.10 which uses latest libvirt etc...
did you create a bug at opennebula ?

It is libvirt that adds that flag. I am not exactly sure, starting
which version it started to do this. It wasn't doing this in libvirt
0.75. I think starting 0.8 it has started to do this.
Unless specified otherwise, by default libvirt marks driver type as
"raw" which gets passed as format flag to kvm. Because of this qcow
virtual size is not exposed to the guest.
OpenNebula, when it creates the libvirt deployment file, doesn't add
any flag. We had to change LibvirtDriver.cc and specifically add
type=qcow2 attribute to the driver xml flag, and recompile one.
Here is a post regarding the same.

Using RC1 I just ran across a bug that was reported in August.
I've included the text of the email below. I just wanted to give
a heads up that it's still there. The weird part is that I have
no idea how it got triggered. I was able to run images yesterday
until about noon. Started playing around with some other images
and from there on out, nothing would start because one kept
requesting the raw flag, including images that had previously been
working.

Hello,
That is really weird as we have not added a format parameter to the
deployment file we use to create a VM. Could you please send us
$ONE_LOCATION/var/<vm_id>/deployment.0 of one of the VM's that fail?
Thank you
