You can create external programs that interact with the Oracle VM Server for SPARC software by means of the Extensible Markup Language (XML) communication mechanism. XML uses the Extensible Messaging and Presence Protocol (XMPP).
An attacker might attempt to exploit this network protocol to access a system, so consider disabling XMPP. For information about disabling XMPP, see XML Transport in Oracle VM Server for SPARC 3.1 Administration Guide . For information about the security mechanisms that Logical Domains Manager uses, see XMPP Server in Oracle VM Server for SPARC 3.1 Administration Guide .
Note that disabling XMPP prevents you from using some key Oracle VM Server for SPARC features such as domain migration, memory dynamic reconfiguration, and the ldm init-system command. Disabling XMPP also prevents Oracle VM Manager or Ops Center from managing the system.
