+blockdev-remove-medium
+----------------------
+
+Removes a medium (a block driver state tree) from a block device. That block
+device's tray must currently be open (unless there is no attached guest device).
+
+If the tray is open and there is no medium inserted, this will be a no-op.
+
+Arguments:
+
+- "device": block device name (json-string)
+
