Hi all,

I'm using this hook script : http://gerrit.ovirt.org/gitweb?p=vdsm.git;a=blob;f=vdsm_hooks/vmdisk/before_vm_start.py;h=191d5c1af533e11d699b1d715d3c1ea60e28b787;hb=6817f1c6e3f5bc137d1f3bef45a2d0191465c7a3 My goal is to boot a vm on a vm image imported form libvirt/kvm. I want to use this single image, that is to say without importing it into ovirt with tools like v2v. acathrow told me on irc that I'd have to change the boot order in the xml, but I don't know how to proceed for many reasons:

 * I can't create a vm through the UI which would boot on the disk
   created by the hook script without first creating a disk on the
   relevant storage domain. If I try I have those warnings :

   hook: Cannot run VM without at least one bootable disk.
   Alternatives:
   -Create a disk for this VM, and rerun the VM.
   -Change the boot sequence using the Edit VM command (Boot Option
   Sub-Tab).
   -Use the Run-Once command to select a different boot option and
   rerun the VM.
 * If I run a vm with the first disk from the storage domain and an
   additional disk from the hook script, how could I change the boot
   order in the xml definition file if I don't know the xml definition
   of the main disk?


thanks all for your help
