[Xen-ia64-devel] [Q] About xc.domain_destroy_hook

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

I have a question.

XendDomainInfo.py:
    def shutdown(self, reason):
        """Shutdown a domain by signalling this via xenstored."""
        log.debug('XendDomainInfo.shutdown(%s)', reason)
<<snip>>
        # HVM domain shuts itself down only if it has PV drivers
        if self.info.is_hvm():
            hvm_pvdrv = xc.hvm_get_param(self.domid, HVM_PARAM_CALLBACK_IRQ)
            if not hvm_pvdrv:
                code = REVERSE_DOMAIN_SHUTDOWN_REASONS[reason]
    here! -->   xc.domain_destroy_hook(self.domid)
                log.info("HVM save:remote shutdown dom %d!", self.domid)
                xc.domain_shutdown(self.domid, code)

[Q] The line does not need, does it?


When I tested xm shutdown command for an HVM domain, I saw the 
following error message in xend-debug.log. 

  Nvram save successful!
  ERROR Internal error: Save to nvram fail!
   (9 = Bad file descriptor)

Also same message was seen in xm reboot command. 

  Nvram save successful!
  ERROR Internal error: Save to nvram fail!
   (9 = Bad file descriptor)

I think that xc.domain_destroy_hook() is called twice.

Best regards,
 Kan
