Abstract

Embodiments of the invention provide for systems and computer program products for management of logically partitioned computing resources of a data processing system configured with hypervisors that each manages one or more logical partitions of the computing resources. The data processing system is configured with domains, and allocated to each domain are one or more hypervisors and logical partitions managed thereby. For a first domain, a token is received from a second domain. The token identifies available computing resources of the second domain that are available for temporary allocation. The data processing system determines whether the available computing resources of the second domain are needed by the first domain based at least in part on the received token. Responsive to determining that the available computing resources are needed by the first domain, the available computing resources are temporarily allocated to the first domain for use thereby.

Claims

1-15. -15. (canceled)

16. A data processing system comprising:

a plurality of logically partitioned computing resources including a plurality of processors and a plurality of memory resources;

a plurality of hypervisors that each manages one or more logical partitions of computing resources, wherein the data processing system is configured with a plurality domains, and allocated to each domain are one or more hypervisors of the plurality and logical partitions managed thereby;

a memory that stores program code configured to be executed by at least one processor to cause the at least one processor to;

receive, at a first domain of the plurality of domains and from a second domain of the plurality of domains, a token that identifies an amount and type of available computing resources of the second domain that are available for temporary allocation;

determine whether the available computing resources of the second domain are needed by the first domain based at least in part on the received token; and

in response to determining that the available computing resources are needed by the first domain, temporarily allocate the available computing resources to the first domain for use thereby.

17. The data processing system of claim 16, wherein the program code is further configured to:

at the first domain, process the token to update a computing resource map associated with the first domain based on the token to indicate the amount and type of computing resources of the second domain that are available for temporary allocation.

18. The data processing system of claim 16, wherein the program code is further configured to:

select a management hypervisor for the second domain from the one or more hypervisors allocated to the second domain based at least in part on availability of the logical partitions managed by the management hypervisor;

analyze, with the management hypervisor, computing resource availability for the one or more hypervisors and the logical partitions allocated to the second domain; and

generate, with the management hypervisor, the token based at least in part on the determined computing resource availability.

19. The data processing system of claim 16, wherein the data processing system includes, for each hypervisor of the plurality of hypervisors, an associated memory that stores a primary domain identifier and an owning domain identifier, the available computing resources temporarily allocated to the first domain includes a particular hypervisor, and the program code is further configured to:

in response to temporarily allocating the available computing resources to the first domain, set the owning domain identifier of the particular hypervisor to identify the first domain.

20. A computer program product, comprising:

a non-transitory computer readable medium; and

program code stored on the computer readable medium and configured to be executed by at least one processor to cause the at least one processor to;

for a data processing system configured with a plurality of hypervisors that each manages one or more logical partitions of the computing resources, the data processing system is configured with a plurality domains, and allocated to each domain are one or more hypervisors of the plurality and logical partitions managed thereby, receive, at a first domain of the plurality of domains and from a second domain of the plurality of domains, a token that identifies an amount and type of available computing resources of the second domain that are available for temporary allocation;

determine whether the available computing resources of the second domain are needed by the first domain based at least in part on the received token; and

in response to determining that the available computing resources are needed by the first domain, temporarily allocate the available computing resources to the first domain for use thereby.
