Proxy tool for guest machine relocation

A method for relocating an original guest from a first host to a second host in a z/VM environment, comprising:

• bringing the original guest down at the first host, wherein the original guest includes a predetermined virtual internet protocol address (VIPA);
• bringing up a new guest at the second host, wherein the new guest has the predetermined VIPA;
• autologging on a first virtual machine (VM) at the second host that provides a VM TCP/IP stack to an interface with a virtual switch;
• launching a second VM to 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
• launching a third VM for determining a status of the virtual switch and advertising to the network a host route of the new guest, wherein the third VM is launched by the first VM.

A computer program product for automating the processing of a new guest at a host in a virtual machine (VM) environment, the computer program product comprising:

• a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:
• program code for autologging on a first VM at the host that provides a VM TCP/IP stack to an interface with a virtual switch;
• program code for launching a second VM to 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
• program code for launching a third VM for determining a status of the virtual switch and advertising to the network a host route of the new guest, wherein the third VM is launched by the first VM.
