For example, the faulty VNFC is VNFC-1, and the VNFC The identifier of the first virtual machine to which -1 belongs is VM1-ID.

Step 38: The EMS uses the VM ID as a primary correlation factor according to the service (application) failure condition. The first NFVI resource information is obtained and displayed in the mapping relationship between the identifier of the pre-stored virtual machine and the NFVI resource information, so as to further determine the path information of the failed physical host, so that the user can quickly locate the problem according to the fault details. The specifics are as follows:
