SYSTEMS AND METHODS FOR MIGRATION OF COMPUTING RESOURCES BASED ON INPUT/OUTPUT DEVICE PROXIMITY
In accordance with embodiments of the present disclosure, an information handling system may include a plurality of host systems and a hypervisor manager comprising a program of instructions configured to, when read and executed by a processor of one of the plurality of host systems, in response to a command for migrating a computing resource executing on one of the plurality of host systems, select a host system as a target for migrating the computing resource based on a proximity of input/output devices of the host system with respect to a proximity domain of the host system, and migrate the computing resource to the host system selected as the target.
1 . An information handling system comprising:
a plurality of host systems; and
a hypervisor manager comprising a program of instructions configured to, when read and executed by a processor of one of the plurality of host systems:
in response to a command for migrating a computing resource executing on one of the plurality of host systems, select a host system as a target for migrating the computing resource based on a proximity of input/output devices of the host system with respect to a proximity domain of the host system; and
migrate the computing resource to the host system selected as the target.
2 . The information handling system of claim 1 , wherein selecting the host system selected as the target comprises selecting the host system selected as the target such that the host system selected as the target satisfies a condition that the input/output devices and processing resources for the computing resource after migration are within a single proximity domain.
3 . The information handling system of claim 2 , wherein the single proximity domain comprises a Non-Uniform Memory Access domain and input/output devices of such Non-Uniform Memory Access domain.
4 . The information handling system of claim 2 , wherein selecting the host system selected as the target comprises reading proximity domain information for hardware resources of the information handling system.
5 . The information handling system of claim 1 , wherein the computing resource comprises a virtual machine.
6 . A method comprising, in an information handling system comprising a plurality of host systems:
in response to a command for migrating a computing resource executing on one of the plurality of host systems, selecting a host system as a target for migrating the computing resource based on a proximity of input/output devices of the host system with respect to a proximity domain of the host system; and
migrating the computing resource to the host system selected as the target.
7 . The method of claim 6 , wherein selecting the host system selected as the target comprises selecting the host system selected as the target such that the host system selected as the target satisfies a condition that the input/output devices and processing resources for the computing resource after migration are within a single proximity domain.
8 . The method of claim 7 , wherein the single proximity domain comprises a Non-Uniform Memory Access domain and input/output devices of such Non-Uniform Memory Access domain.
9 . The method of claim 7 , wherein selecting the host system selected as the target comprises reading proximity domain information for hardware resources of the information handling system.
10 . The method of claim 6 , wherein the computing resource comprises a virtual machine.
11 . An article of manufacture comprising:
a non-transitory computer-readable medium; and
computer-executable instructions carried on the computer-readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to, in an information handling system comprising a plurality of host systems:
in response to a command for migrating a computing resource executing on one of the plurality of host systems, selecting a host system as a target for migrating the computing resource based on a proximity of input/output devices of the host system with respect to a proximity domain of the host system; and
migrating the computing resource to the host system selected as the target.
12 . The article of claim 11 , wherein selecting the host system selected as the target comprises selecting the host system selected as the target such that the host system selected as the target satisfies a condition that the input/output devices and processing resources for the computing resource after migration are within a single proximity domain.
13 . The article of claim 12 , wherein the single proximity domain comprises a Non-Uniform Memory Access domain and input/output devices of such Non-Uniform Memory Access domain.
14 . The article of claim 12 , wherein selecting the host system selected as the target comprises reading proximity domain information for hardware resources of the information handling system.
15 . The article of claim 11 , wherein the computing resource comprises a virtual machine.
