About Crash Dumps

On a running system, the hypervisor's memory is completely off-limits to dom0. If the hypervisor crashes, however, the resulting panic dump will generate a core file that provides a unified view of both xVM and dom0. In this core file, xVM appears as a Solaris kernel module named xpv. For example:

 > $c

The following applies to crash dumps:

  • If a dom0 crashes with a standard Solaris panic, the dump will include only the dom0.

  • When the hypervisor itself panics, the resulting dump includes the xVM state as well as the dom0 state.
