Providing Dynamic Topology Information in Virtualized Computing Environments

摘要

Systems and methods for providing dynamic topology information to virtual machines hosted by a multi-processor computer system supporting non-uniform memory access (NUMA). An example method may comprise assigning, by a hypervisor executing on a computer system, unique identifiers to a plurality of memory blocks residing on a plurality of physical nodes; determining that a memory block has been moved from a first physical node to a second physical node; determining memory access latency values to the second physical node by a plurality of virtual processors of the computer system; and updating, using a unique identifier of the memory block, a data structure storing memory access latency information, with the memory access latency values for the memory block.

1. A method, comprising:
assigning, by a hypervisor executing on a computer system, unique identifiers to a plurality of memory blocks residing on a plurality of physical nodes, wherein at least two memory blocks of the plurality of memory blocks reside on one physical node; determining that a memory block has been moved from a first physical node to a second physical node; determining memory access latency values to the second physical node by a plurality of virtual processors of the computer system; and updating, using a unique identifier of the memory block, a data structure storing memory access latency information, with the memory access latency values for the memory block.
