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.<br>
<br>
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.<br>
<br>
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.<br>
<br>
Here is a post regarding the same.<br>

<p class=MsoNormal><span style='font-size:10.0pt'>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.<br>
