A.3. Extending VDSM with Hooks

This chapter describes how to extend VDSM with event-driven hooks. Extending VDSM with hooks is an experimental technology, and this chapter is intended for experienced developers. Note that at this time hooks are not able to run on Red Hat Enterprise Virtualization Hypervisors, they must only be used on Red Hat Enterprise Linux hosts. By setting custom properties on virtual machines it is possible to pass additional parameters, specific to a given virtual machine, to the hook scripts.
