+---------------------
+
+Insert a new media in a removable drive. The tray must be empty and already
+opened. The tray is not automatically closed (please, see blockdev-tray-open
+and blockdev-tray-close commands).
+
+Arguments:
+
+- "device": device name (json-string)
+- "media": media file path (json-string)
+- "format": media file format (json-string, optional)
+
+Example:
+
+-> { "execute": "blockdev-media-insert",
+ "arguments": { "device": "ide1-cd0",
+ "media": "/srv/images/Fedora-12-x86_64-DVD.iso" } }
+<- { "return": {} }
+
+Note: If the media is encrypted, the command block_passwd has to be used to
+ set the media's password.
