Well, it sounds feasible to provide a hooking mechanism that enables to alter the domain
XML in the engine, at some point.
I'm not sure though that it could actually replace the hooks in VDSM since:
1. The XML won't be complete (host-specific configuration will be missing).
2. If the user wants to do some operation on the host with the hook, he'll need to
send a request from the engine to the host, which is more complicated.
Still, many hooks are intended only for feature velocity - to make use
of a libvirt feature without disturbing Engine or Vdsm.
It makes a lot of sense to add a hooking point on Engine side, where
people can plug their code.
