Abstract

Disclosed herein are methods, systems, and computer program products for the placement of a virtual machine within a plurality of cache-coherent NUMA servers. According to an aspect, an example method includes determining a resource requirement of the virtual machine. The example method may also include determining a resource availability of one or more nodes of the plurality of servers. Further, the example method may include selecting placement of the virtual machine within one or more nodes of the plurality of cache-coherent NUMA servers based on the determined resource requirement and the determined resource availability.

Claims

1. A method for placement of a virtual machine within a plurality of servers, the method comprising:

using at least a processor and memory for;

determining a resource requirement of the virtual machine;

determining a resource availability of one or more nodes of the plurality of servers; and

selecting placement of the virtual machine within one or more nodes of the plurality of servers based on the determined resource requirement and the determined resource availability.

2. The method of claim 1, wherein determining the resource availability comprises determining an amount of physical memory available within at least one of the one or more nodes of the plurality of servers.

3. The method of claim 2, wherein selecting placement of the virtual machine comprises selecting placement of the virtual machine based on the amount of physical memory available within the at least one of the one or more nodes of the plurality of servers.

4. The method of claim 1, wherein selecting placement of the virtual machine comprises selecting placement of the virtual machine within one or more nodes of one physical server among the plurality of servers.

5. The method of claim 1, wherein selecting placement of the virtual machine comprises selecting placement of the virtual machine within one node of the one or more nodes of one physical server among the plurality of servers.

6. The method of claim 1, wherein determining a resource availability comprises determining the resource availability based on a uniform memory access availability.

7. The method of claim 1, wherein at least one of the one or more nodes comprises a memory and a processor.

8. The method of claim 1, wherein the plurality of servers comprises a plurality of non-uniform memory access servers.

9. The method of claim 8, wherein the plurality of non-uniform memory access servers are configured to operate in a server farm.

10. The method of claim 8, wherein the plurality of non-uniform memory access servers are configured to utilize a cache coherent interconnect.

11. The method of claim 1, further comprising using the at least one processor and memory for selecting the virtual machine for migration.

12. The method of claim 11, further comprising using the at least one processor and memory for migrating the virtual machine from a first server of the plurality of servers to a second server of the plurality of servers.

13. The method of claim 11, further comprising using the at least one processor and memory for generating a list of candidate servers of the plurality of servers for placement of the virtual machine.

14. The method of claim 13, wherein selecting placement of the virtual machine comprises migrating the virtual machine from a first server of the plurality of servers to a second server among the list of candidate servers based on the determined resource requirement and the determined resource availability.

15. A system for placement of a virtual machine within a plurality of servers, the system comprising:

a virtual machine placement manager configured to execute and respond to placement requests; and

a resource manager configured to;

determine a resource requirement of the virtual machine;

determine a resource availability of one or more nodes of the plurality of servers; and

select placement of the virtual machine within one or more nodes of the plurality of servers based on the determined resource requirement and the determined resource availability.

16. The system of claim 15, wherein the resource manager is configured to:

determine an amount of physical memory available within at least one of the one or more nodes of the plurality of servers; and

select placement of the virtual machine based on the amount of physical memory available within the at least one of the one or more nodes of the plurality of servers.

17. The system of claim 15, wherein the resource manager is configured to select placement of the virtual machine within one node of the one or more nodes of one physical server of the plurality of servers.

18. The system of claim 15, wherein the resource manager is configured to select placement of the virtual machine within one node of the one or more nodes of one physical server among the plurality of servers.

19. The system of claim 15, wherein the resource manager is configured to determine the resource availability based on a uniform memory access availability.

20. The system of claim 15, wherein at least one of the one or more nodes comprises a memory and a processor.

21. The system of claim 15, wherein the plurality of servers comprises a plurality of non-uniform memory access servers.

22. The system of claim 15, wherein the plurality of non-uniform memory access servers are configured to utilize a cache coherent interconnect.

23. The system of claim 15, wherein the resource manager is configured to:

select the virtual machine for migration; and

migrate the virtual machine from a first server of the plurality of servers to a second server of the plurality of servers.

24. The system of claim 15, wherein the resource manager is configured to:

select the virtual machine for migration;

generate a list of candidate servers of the plurality of servers for placement of the virtual machine; and

migrate the virtual machine from a first server of the plurality of servers to a second server among the list of candidate servers based on the determined resource requirement and the determined resource availability.

25. A computer program product for placement of a virtual machine within a plurality of servers, said computer program product comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code configured to;

determine a resource requirement of the virtual machine;

determine a resource availability of one or more nodes of the plurality of servers; and

select placement of the virtual machine within one or more nodes of the plurality of servers based on the determined resource requirement and the determined resource availability.
