THE IDENTIFY PROTOCOL The IDENTIFY protocol defines a means for virtual machines to identify
themselves to other virtual machines by passing user-defined control
information via a standardVMCF message header. Figure 18 shows the IDENTIFY protocol graphically. When the IDENTIFY subfunction is issued, CP directs an external
interrupt to the sink virtual machine. Along with the external
interrupt, the sink virtual machine receives a standardVMCF message header that contains user-defined information. The IDENTIFY protocol
does not cause a response external interrupt to be directed the source
virtual machine.Source Virtual Machine DMKVMC VMCF Interface Module I I I I I I I I I I I I I I Sink Virtual Machine IDENTIFY--->---------->I I I I I I I I I--External Interrupt-------> I (IDENTIFY Sequence Complete) I I Figure 18. The IDENTIFY Protocol
