Hi Wido
So I take it this old feature request to inject custom domain XML wasn't
implemented in any version of ACS ?
https://cwiki.apache.org/confluence/display/CLOUDSTACK/KVM+hook+script+include
That's for during a migration. That seems to be supported by libvirt.
Not during the start of a VM.

As far as I know you are not able to modify the XML with hooks.
You can act upon the hook prior to starting the VM by looking at the XML
and preparing some resources for the VM, but you can't change anything
at that point.
Please do correct me if I'm wrong.
