I'm testing hooks in vdsm and I need some help on modifying one of your pyhton script : vmdisk (http://gerrit.ovirt.org/gitweb?p=3Dvdsm.git;a=3Dblob;f=3Dvdsm_hooks/vm= disk/before_vm_start.py;h=3D191d5c1af533e11d699b1d715d3c1ea60e28b787;hb=3D6= 817f1c6e3f5bc137d1f3bef45a2d0191465c7a3)
the hook works great and I'm able now to attach a file device as a second disk. But I want this disk to be the first bootable disk instead of the block device one created into the engine. In order to change the boot order of the disk, I added those lines:

...
source =3D domxml.createElement('source')
source.setAttribute('file', devpath)
disk.appendChild(source)

boot =3D domxml.createElement('boot')
boot.setAttribute('order', 1)
disk.appendChild(boot)

 # find a name for vdXXX
.....

So the hook permit <boot order=3D1> item (http://libvirt.org/formatdomain.html#elementsDisks= )

But the vm refuses booting without any logs anywhere...

What is wrong?

Thanks for your help
