[one-users] Do not use qcow image format with latest ONE

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.

--------------------- PREVIOUS REPORT BELOW -----------------------


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
