Hi all,
I'm using this hook script :
http://gerrit.ovirt.org/gitweb?p=vdsm.git;a=blob;f=vdsm_hooks/vmdisk/befo...
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

1. i guess you can change the script to fix the boot order.
2. you can create a VM with a disk the same size, and just copy your
converted disk over it (cp for nfs, dd for iscsi), instead of using the
hook.

converted disk over it (cp for nfs, dd for iscsi), instead of using
the hook.
Today you cannot do that because the hook didn't designed to do
that.
By modifying the hook you can add a <boot order='1'/> to the disk and
change
the other device boot order to higher number.
Take a look at this links:
http://libvirt.org/formatdomain.html#elementsDisks
http://libvirt.org/formatdomain.html#elementsNICSBoot
and look for the string 'boot order'

Tanks all exactly what I was looking for :)
