Generating a virtual machines relocation protocol

A system for facilitating relocating virtual machines, the system comprising:

• a memory;
• and
• a processing circuit communicatively coupled with the memory, wherein the system performs a method comprising:
• obtaining, by a first controller, first power-related information from a first power system set comprising one or more first power systems that provide power to a first set of powered hardware components with which the first controller is associated, the first set of powered hardware components running a first plurality of virtual machines, and the first power-related information including an estimated amount of time to power failure to the first set of powered hardware components;
• determining, by the first controller, that the estimated amount of time to power failure is an insufficient amount of time to live-migrate all virtual machines of the first plurality of virtual machines;
• obtaining, by the first controller, network power-related information from a power system providing power to a network with a data transfer path from the first set of powered hardware components to a second set of powered hardware components, where the power system providing power to the network is other than the one or more first power systems providing power to the first set of powered hardware components;
• dynamically generating, by the first controller, a relocation protocol for migrating the first plurality of virtual machines based, at least in part, upon the first power-related information and the network power-related information, the relocation protocol being an emergency relocation protocol dynamically generated based, at least in part, on the estimated amount of time to power failure to the first set of powered hardware components being insufficient to live-migrate all virtual machines of the first plurality of virtual machines, and the generating comprising assigning, by the first controller, a virtual machine of the first plurality of virtual machines to a first subset of one or more virtual machines of the first plurality of virtual machines to be live migrated or a second subset of one or more virtual machines of the first plurality of virtual machines to be snapshotted for migration, the assigning being based, at least in part, upon the first power-related information and the network power-related information, including the estimated amount of time to power failure, the relocation protocol including:
• a live migration of the first subset of one or more virtual machines of the first plurality of virtual machines so that the first subset of virtual machine(s) is to be migrated to and run on a second set of powered hardware components, the live migration being in a manner such that the first subset of virtual machine(s) continues to operate in a continuous manner through the migration;
• and
• a snapshotting of the second subset of one or more virtual machines of the first plurality of virtual machines at the first set of powered hardware components;
• and
• migrating the first plurality of virtual machines, using the relocation protocol, to the second set of powered hardware components.

A computer program product for facilitating relocating virtual machines, the computer program product comprising:

• a non-transitory computer-readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
• obtaining, by a first controller, first power-related information from a first power system set comprising one or more first power systems that provide power to a first set of powered hardware components with which the first controller is associated, the first set of powered hardware components running a first plurality of virtual machines, and the first power-related information including an estimated amount of time to power failure to the first set of powered hardware components;
• determining, by the first controller, that the estimated amount of time to power failure is an insufficient amount of time to live-migrate all virtual machines of the first plurality of virtual machines;
• obtaining, by the first controller, network power-related information from a power system providing power to a network with a data transfer path from the first set of powered hardware components to a second set of powered hardware components, where the power system providing power to the network is other than the one or more first power systems providing power to the first set of powered hardware components;
• dynamically generating, by the first controller, a relocation protocol for migrating the first plurality of virtual machines based, at least in part, upon the first power-related information and the network power-related information, the relocation protocol being an emergency relocation protocol dynamically generated based, at least in part, on the estimated amount of time to power failure to the first set of powered hardware components being insufficient to live-migrate all virtual machines of the first plurality of virtual machines, and the generating comprising assigning, by the first controller, a virtual machine of the first plurality of virtual machines to a first subset of one or more virtual machines of the first plurality of virtual machines to be live migrated or a second subset of one or more virtual machines of the first plurality of virtual machines to be snapshotted for migration, the assigning being based, at least in part, upon the first power-related information and the network power-related information, including the estimated amount of time to power failure, the relocation protocol including:
