</span>Guest agent hooks aren’t triggered through the SDK, hooks are triggered when certain events happen on the hypervisor side.<br class="">
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<br class="">
agent asking it to process all hooks.<br class="">
<br class="">
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.<br class="">
