ConVirt / Discussion / Help & Support: Shutdown Windows VMs

Christian Loretan - 2008-12-15

Hi /jd
It's me again. I've encountered a strange behavior with the "Shutdown" button and Windows. The system will not shutdown cleanly, it stop like poweroff. If i do "xm shutdown <domain>" Windows say goodby as expected (ok there are people, who say that a Windows shutdown is normaly a crash ;-)). If i reboot Windows with the "Reboot" button, it works like expected. The difference between the "shutdown commands" are visible in /var/log/xen/xend.log
Convirt shutdown:
DEBUG (XendDomainInfo:467) XendDomainInfo.shutdown(halt)
DEBUG (XendDomainInfo:1114) XendDomainInfo.handleShutdownWatch
DEBUG (XendDomainInfo:1114) XendDomainInfo.handleShutdownWatch
INFO (XendDomainInfo:1295) Domain has shutdown: name=<VMName> id=49 reason=halt.

xm shutdown:
DEBUG (XendDomainInfo:467) XendDomainInfo.shutdown(poweroff)
DEBUG (XendDomainInfo:1114) XendDomainInfo.handleShutdownWatch
DEBUG (XendDomainInfo:1114) XendDomainInfo.handleShutdownWatch
INFO (XendDomainInfo:1295) Domain has shutdown: name=<VMName> id=51 reason=poweroff.

In first DEBUG line "Convirt" send halt and "xm shutdown" poweroff (like xm destroy?) in shutdown command.
Is this behavior by design, or is it customizable over a configfile (Convirt, VM)?

Thanks again for help

  Hi Christian
  
  Good catch. It seems the reason string might have changed or we initially mis-interpreted it.
  For now, Can u please make the following change in src/convirt/core/platforms/xen/XenVMM.py
  
  Old :
      def shutdown(self,id):
          self.xen_proxy.xend.domain.shutdown(id, 'halt')
  
  New :
     def shutdown(self,id):
          self.xen_proxy.xend.domain.shutdown(id, 'poweroff')
  
  Let us know.
  Do you have PV drivers installed ? ACPI enabled ?
  Thanks

    Hi /Jd
    Yes, PV drivers installed and ECPI enabled. But look at this. Your changes in XenVMM.py working well for me. Windows will shutdown savely and clean.
    Thank you for help.
    Regards,
    Christian

  Which set of PV drivers are you using ? Do you mind adding a "How to " entry on the Wiki ?
  Or share some pointer to step by step instructions for other.
  
  Thanks
