7.3.6. Kernel Dump

Red Hat Enterprise Virtualization hypervisor hosts generate a kernel dump (a kdump file) in the event of a system failure. These kdump files are essential for debugging and support.
The hypervisor supports the export of kernel dumps by kdump using NFS or SSH so that they may be analyzed at a later date. The Kernel Dump screen provides for configuration of this facility.
Procedure 7.11. kdump Configuration
  1. Kernel Configuration

    Crash dumps generated by kdump are exported over NFS or SSH. Select the desired transfer method and press Space to enable it.
    For the export method chosen a location to which the kdump files should be exported must also be specified.
    1. NFS location

      Set the NFS location to which crash logs should be exported in the NFS Location field. The NFS Location should be the full NFS path which includes fully qualified domain name and directory path.
      Example 7.12. NFS Location
      example.redhat.com:/var/crash

    2. SSH location

      Set the SSH location to which crash logs should be exported in the SSH Location field. The SSH Location should be the full SSH login which includes the fully qualified domain name and username.
      Example 7.13. SSH Location
      root@example.redhat.com

  2. Save Configuration

    To save the configuration the user must select <Apply> and press Enter.
Result:
The Kernel Dump configuration has been updated and kernel dumps will be exported to the remote server(s) specified.
