[libvirt] [libxl] shutdown a domain before it finishes starting

Hi all: Suppose we have a guest domain which is pvops, for example, rhel6.4. Steps to produce the problem: 1 start the guest by virDomainCreate() 2 the API returns before the guest domain fully available, which means, the disks, network interfaces and some import services are not available inside the guest. 3 we call virDomainShutdown() to shutdown the guest. Expected result: The guest got shutdown. The result in fact: Because the guest is not available when we call virDomainShutdown(), it couldn't respond to our 'shutdown' xenstore request, the guest turns on later, rather than shutting down. So , the question is: In libxl_driver( xen-hypervisor environment), how can we tell that the guest is available or not, and is it suitable to shutdown the guest at that moment? Thanks in advance. Oscar.
