Application initiated negotiations for resources meeting a performance parameter in a virtualized computing environment

A logically partitioned host system in which one or more logical partitions of pools of virtualized resources, and an operating system is operated in each of the logical partitions, comprising:

• a hypervisor operative on the host system to manage the one or more logical partitions of pools of virtualized resources and operative to negotiate to reserve at least one available local resource in the host system that meets a performance parameter for at least one resource specified in a reservation request by a particular logical partition from among the one or more logical partitions, wherein the at least one performance parameter is specified by a particular application initiating the reservation request from the particular logical partition;
• and
• the hypervisor, responsive to determining that the at least one available resource is not available in the host system, operative to negotiate for offers to migrate the particular logical partition to at least one other host system comprising at least one available remote resource that meets the performance parameter, wherein the at least one other host system is managed by at least one other hypervisor for managing at least one other logical partition comprising at least one other pool of virtualized resources.

A computer program product for managing requests for resources, said computer program product tangibly embodied in a computer-readable storage medium and comprising computer executable instructions which cause a computer to:

• negotiate, by a hypervisor, to reserve at least one available local resource in a host system that meets a performance parameter for at least one resource specified in a reservation request by a particular logical partition from among one or more logical partitions of virtualized pools of resources managed by the hypervisor in the host system, wherein the at least one performance parameter is specified by a particular application initiating the reservation request from the particular logical partition;
• and
• responsive to determining that the at least one available resource is not available in the host system, negotiate, by the hypervisor for offers to migrate the particular logical partition to at least one other host system comprising at least one available remote resource that meets the performance parameter, wherein the at least one other host system is managed by at least one other hypervisor that manages one or more other logical partitions of virtualized pools of resources.
