This is trivial with xVM, btw: just make the panic routine call HYPERVISOR_shutdown(SHUTDOWN_crash); and dom0 will automatically create a full crash dump for the domain, which is readably directly in MDB. As a refinement you might want to only do this if a (suitable) place to crash dump isn't available. regards john _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
