 [id="virt-4-21-deprecated_{context}"]
 == Deprecated features
 
+Legacy virtctl ssh target syntax removed::
+The `virtctl ssh` command no longer supports specifying a virtual machine target without an explicit resource type. You must prefix the target name with `vmi/` or `vm`. Scripts and automation that rely on the legacy syntax are no longer supported and must be updated.
