How to Configure 'kdump' for Oracle VM 2.2.X (Doc ID 1130030.1)

Last updated on JULY 17, 2023

Applies to:

Oracle VM - Version 2.2 to 2.2.2 [Release OVM22 to OVM222]
Oracle Cloud Infrastructure - Version N/A and later
Linux x86


If an Oracle VM server (physical server) encounters a dom0-wide problem (like a crash, hang, reboot etc.) the system memory dump (vmcore) would be very useful for the problem analysis to find the root cause of the issue. To be able to get a useful vmcore dump, a proper kdump service configuration will be required.

As <Document 452067.1> describes the procedure for configuring kdump for Oracle Linux 5, the Oracle VM 2.2.X kdump configuration is similar. Still due to some differences due to the design of the Oracle VM dom0, the procedure is also slightly different although the fundemental concept is the same.

This document provides step-by-step instructions on how to configure kdump on Oracle VM 2.2.X. Please also see <Document 1132003.1> to be able to get a usable vmcore dump for Oracle VM 2.2 with RAM > 4GB.
