+pre/post-migrate
+~~~~~~~~~~~~~~~~
+Those hooks run before/after a VM migrates from one host to another. This
+hook is a bit special, since it gets executed on the source node as well as the
+target node. In order for this hookscript to function properly, the configured
+script file needs to be available on both nodes. If it is a local script, this
+means storing it on both server under the same path. The preferred option
+would be storing the hookscript on a shared storage, so it is accessible from
+both nodes.
