Guest agent hooks aren’t triggered through the SDK, hooks are triggered when certain events happen on the hypervisor side.
e.g. A VM gets migrated from HOST A to HOST B or the VM gets suspended. In these cases VDSM _can_ send a message to the guest
agent asking it to process all hooks.

That those hooks are enabled are depending on the migration policy configured. Currently all but the ‘Legacy’  migration policies do cause the hooks to be executed, given a new enough guest agent, VDSM and cluster version.
