Patent ID: 8640127

Claim:
A system comprising: at least one computing device having a hardware processor, the at least one computing device including a tool that runs on a z/VM host for automating the processing of a new guest, the tool including: a first virtual machine (VM) that autologs onto the z/VM host, the first VM being configured to act as a VM Transmission Control Protocol/Internet Protocol (TCP/IP) stack that provides an interface between the new guest and a virtual switch; a second VM that provides a VM multiprotocol server configured for OSPF (Open Shortest Path First) to run with the VM TCP/IP stack to generate a host route for the new guest, wherein the second VM is launched by the first VM; and a third VM configured to monitor whether the new guest is coupled to a virtual network interface card (NIC), and to monitor whether the virtual NIC is under control of the VM TCP/IP stack, the third VM further configured to determine a status of the virtual switch by determining whether the NIC is active and whether an eligible host route has been stored for the guest VM, the third VM further configured to build a host route using the stored eligible host route on behalf of the new guest, and the third VM further configured to advertise to the network, via the virtual switch, the host route for the new guest, wherein the third VM is launched by the first VM.
