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

The vdsm package you are importing from is rather new and did not exist in vdsm-4.9.3.2. You should probably use the hooks from http://gerrit.ovirt.org/gitweb?p=3Dvdsm.git;a=3Dtree;f=3Dvdsm_hooks;hb=3Dv4= .9.3.2 when vdsm-4.9.3.2 is installed.
