Abstract

A computer-implemented method, carried out by one or more processors, for policy based virtual resource allocation. In an embodiment, the method includes identifying a number of host resources specified by host resource requirements for a first resource consumer. The method determines if the host resource requirements include a list of host resource pools for the first resource consumer. Responsive to determining that the host resource requirements include the list of host resource pools for the first resource consumer, a first set of eligible host resource pools is identified. An allocation policy may be identified, where the allocation policy includes one or more parameters for allocating host resources. Host resources from the first set of eligible host resource pools are allocated based on the allocation policy.

First claim

1 - 7 . (canceled)

8 . A computer program product for policy based virtual resource allocation, the computer program product comprising:
one or more computer readable tangible storage media and program instructions stored on at least one of the one or more storage media, the program instructions comprising: program instructions to identify a number of host resources specified by host resource requirements for a first resource consumer; program instructions to determine if the host resource requirements include a list of host resource pools for the first resource consumer; responsive to determining that the host resource requirements includes the list of host resource pools for the first resource consumer, program instructions to identify a first set of eligible host resource pools; program instructions to identify an allocation policy, wherein the allocation policy includes one or more parameters for allocating host resources; and program instructions to allocate host resources from the first set of eligible host resource pools based on the allocation policy.

9 . The computer program product of claim 8 , further comprising program instructions, stored on the one or more computer readable storage media, which when executed by a processor, to:
responsive to determining the host resource requirements do not include the list of host resource pools for a second resource consumer, identify one or more host resource characteristics; identify a second set of eligible host resource pools; and allocate host resources from the second set of eligible host resource pools based on the allocation policy.

10 . The computer program product of claim 8 , further comprising program instructions, stored on the one or more computer readable storage media, which when executed by a processor, to:
determine a quality of a current resource allocation for the first resource consumer; determine a quality of a new resource allocation for the first resource consumer; and responsive to determining the quality of the new resource allocation for the first resource consumer exceeds the quality of the current resource allocation for the first resource consumer, reallocate host resources based on the new resource allocation.

11 . The computer program product of claim 9 , further comprising program instructions, stored on the one or more computer readable storage media, which when executed by a processor, to:
determine a quality of a current resource allocation for the second resource consumer; determine a quality of a new resource allocation for the second resource consumer; and responsive to determining the quality of the new resource allocation for the second resource consumer does not exceed the quality of the current resource allocation for the first resource consumer, determine not to reallocate based on the new resource allocation.

12 . The computer program product of claim 8 , wherein the one or more parameters of the allocation policy include maximum availability, maximum capacity, lowest utilization, and priority.

13 . The computer program product of claim 8 , wherein the host resource requirements include mandatory allocation requirements and optional allocation requirements.

14 . The computer program product of claim 9 , wherein the one or more host resource characteristics specify one or more of an adapter type, a connectivity type for an adapter, and an accelerator engine.

15 . A computer system for policy based virtual resource allocation, the computer system comprising:
one or more computer processors; one or more computer readable storage media; and program instructions stored on the computer readable storage media for execution by at least one of the one or more computer processors, the program instructions comprising: program instructions to identify a number of host resources specified by host resource requirements for a first resource consumer; program instructions to determine if the host resource requirements include a list of host resource pools for the first resource consumer; responsive to determining that the host resource requirements includes the list of host resource pools for the first resource consumer, program instructions to identify a first set of eligible host resource pools; program instructions to identify an allocation policy, wherein the allocation policy includes one or more parameters for allocating host resources; and program instructions to allocate host resources from the first set of eligible host resource pools based on the allocation policy.

16 . The computer system of claim 15 , further comprising program instructions, stored on the one or more computer readable storage media, which when executed by a processor, to:
responsive to determining the host resource requirements do not include the list of host resource pools for a second resource consumer, identify one or more host resource characteristics; identify a second set of eligible host resource pools; and allocate host resources from the second set of eligible host resource pools based on the allocation policy.

17 . The computer system of claim 15 , further comprising program instructions, stored on the one or more computer readable storage media, which when executed by a processor, to:
determine a quality of a current resource allocation for the first resource consumer; determine a quality of a new resource allocation for the first resource consumer; and responsive to determining the quality of the new resource allocation for the first resource consumer exceeds the quality of the current resource allocation for the first resource consumer, reallocate host resources based on the new resource allocation.

18 . The computer system of claim 16 , further comprising program instructions, stored on the one or more computer readable storage media, which when executed by a processor, to:
determine a quality of a current resource allocation for the second resource consumer; determine a quality of a new resource allocation for the second resource consumer; and responsive to determining the quality of the new resource allocation for the second resource consumer does not exceed the quality of the current resource allocation for the first resource consumer, determine not to reallocate based on the new resource allocation.

19 . The computer system of claim 15 , wherein the one or more parameters of the allocation policy include maximum availability, maximum capacity, lowest utilization, and priority.

20 . The computer system of claim 15 , wherein the host resource requirements include mandatory allocation requirements and optional allocation requirements.
