  1. Boot Xen and Dom-0. For details on how to boot Xen and Dom-0, refer to PetaLinux Tools Documentation: Reference Guide (UG1144).
  2. Enable Xen awareness by enabling OS aware debug for Xen symbol file. Symbol files are added to a process context to enable source level debugging. For details on how to enable Xen awareness, refer to Enabling Xen Awareness.
  3. Debug Dom-0 kernel.
    1. Enable OS awareness on the Linux symbol file in the Debug view for Dom-0 VCPU context. For details on OS aware debug, refer to OS Aware Debugging.
    2. Suspend the Dom-0 VCPU#0 core. You can now insert breakpoints, step in, step out, watch variables, stack trace or perform other source level debugging tasks.

  4. Debug the Dom-U Kernel:
    1. Copy the guest Linux images to Dom-0 file system.
    2. Create a Dom-U guest.
    3. Enable OS awareness on the Linux symbol file in the Debug view for Dom-U VCPU context. For details on OS aware debug, refer OS Aware Debugging.
    4. Suspend the Dom-U VCPU#0 core. You can now insert breakpoints, step in, step out, watch variables, stack trace or perform other source level debugging tasks.
