A device calculates a memory oversubscription threshold for a virtual machine (VM). Based on the memory oversubscription threshold, the device determines a first memory size to be physically allocated to the VM, and a second memory size to be oversubscribed to the VM. The device configures a first virtual non-uniform memory access (NUMA) node comprising a virtual processor and a first virtual memory having the first memory size. The device allocates a first physical memory to back the first virtual memory. The device configures a second virtual NUMA node comprising a second virtual memory having the second memory size. The second virtual NUMA node is a computeless NUMA node. The device configures the VM to use the first virtual NUMA node and the second virtual NUMA node. Based on the second virtual NUMA node being computeless, the VM funnels a memory access to the first virtual memory.
