I cloned the git tree and copied the script in
/usr/libexec/vdsm/hooks/before_vm_start/

Hello,
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=vdsm.git;a=blob;f=vdsm_hooks/vmdisk/before_vm_start.py;h=191d5c1af533e11d699b1d715d3c1ea60e28b787;hb=6817f1c6e3f5bc137d1f3bef45a2d0191465c7a3)
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 = domxml.createElement('source')
source.setAttribute('file', devpath)
disk.appendChild(source)
boot = domxml.createElement('boot')
boot.setAttribute('order', 1)
disk.appendChild(boot)
# find a name for vdXXX
.....
So the hook permit<boot order=1> item
(http://libvirt.org/formatdomain.html#elementsDisks)
But the vm refuses booting without any logs anywhere...
What is wrong?
Thanks for your help
Hi,
1. try to change the number to string:
boot.setAttribute('order', '1')
2. you have a libvirt log at /var/log/libvirt/qemu/youvmname.log
3. when the script enumerate all the disks you need to change the other disk
boot order:
for d in xmldisks:
# here look in each disk for boot element and change its order attribute
# to other number, ie 2, 3 ...
