A method of the disclosure includes determining, by a virtual machine (VM) executed by a processing device and managed by a hypervisor, that a memory page of the guest is to be moved from a first virtual non-uniform memory access (NUMA) node of the VM to a second virtual NUMA node of the VM. The method further includes updating, by the VM in a guest page table, upper bits of a guest physical address (GPA) of the memory page to include a host address space identifier (HASID) of the second virtual NUMA node, and causing an execution control to be transferred from the VM to the hypervisor due to a page fault resulting from attempting to access the updated GPA."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Host address space identifier for non-uniform memory access locality in virtual machines","description":"Aspects of the disclosure provide for implementing host address space identifiers for non-uniform memory access (NUMA) locality in virtual machines.
