INSTANTIATING A VIRTUAL MACHINE WITH A VIRTUAL NON-UNIFORM MEMORY ARCHITECTURE

Techniques for effectuating a virtual NUMA architecture for virtual machines are disclosed herein. In an embodiment, a system determines the physical topology of a datacenter. When instantiating a virtual machine, the system determines a number of NUMA nodes for that VM based on the physical topology. The system then directs a second system to instantiate the virtual machine with the determined number of NUMA nodes.
