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 xpv`panic+0xbf() xpv`do_crashdump_trigger+0x19() xpv`keypress_softirq+0x35() xpv`do_softirq+0x54() xpv`idle_loop+0x55()
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.
