Environment

SUSE Linux Enterprise Server 10 SP1
SUSE Linux Enterprise Server 10

Situation

Troubleshooting of a privileged (Dom0) Xen kernel is needed.

Resolution

The "kdump" method of capturing a kernel crash dump described in TID 3374462 - Configure kernel core dump capture is not supported for Xen-enabled kernels prior to SLES 10 SP2.

To troubleshoot a crashing Xen kernel in Dom0 using the GNU debugger gdb, proceed as follows:

Set up a serial console. Refer to TID 3456486 - Configuring a Remote Serial Console for SLES.
Refer to the /usr/share/doc/packages/xen/README.SuSEfor general information about troubleshooting Xen-related issues.
Refer to the /usr/share/doc/packages/xen/misc/crashdb.txt file from the "xen-tools" package for details on how to connect gdb to the crashed system.
