If you are in need to diagnosing problems with Oracle VM Server where you experience some unavailability or unconditional shutdowns, it would be very useful to have a serial console attached to the Oracle VM Server (where some blade systems provide specific mechanisms for that) and get the system messages relayed there too.

It may be crucial to have a serial console setup if nothing relevant / useful are being dumped into /var/log/messages or into other logs. Still, there is another method called Netconsole (See <Document 793684.1>). If netconsole is not feasible or possible, you may still need the option of a serial console.

In principle, the serial console configuration for Oracle VM 2.2 is not much different from a generic serial console setup for Linux OS described in <Document 228204.1>. Due to some different default setup in Oracle VM from Oracle Linux 5, the configuration steps needs to be slightly different.
