Hybrid virtual machines having physically backed and virtually backed memory ranges

A computer system, comprising:

• a processor system;
• a memory;
• and
• a computer storage medium that stores computer-executable instructions that are executable by the processor system to at least:
• identify a first set of guest-physical memory pages within a virtual machine (VM) address space to be backed by host-physical addresses (HPAs) corresponding to host-physical memory pages within the memory;
• map each guest-physical memory page in the first set of guest-physical memory pages to a different physical memory page within the memory, including, for each guest-physical memory page in the first set of guest-physical memory pages, mapping a corresponding guest-physical address (GPA) to a corresponding HPA;
• identify a second set of guest-physical memory pages within the VM address space to be backed by host-virtual addresses (HVAs);
• map each guest-physical memory page in the second set of guest-physical memory pages to a different HVA, including, for each guest-physical memory page in the second set of guest-physical memory pages, mapping a corresponding GPA to a corresponding HVA;
• and
• distinguish the first set of guest-physical memory pages from the second set of guest-physical memory pages to the VM.

A computer storage medium that stores computer-executable instructions that are executable by a processor system of a virtual machine (VM) host computer system to at least:

• identify a first set of guest-physical memory pages within a VM address space to be backed by host-physical addresses (HPAs) corresponding to host-physical memory pages within a memory of the VM host computer system;
• map each guest-physical memory page in the first set of guest-physical memory pages to a different physical memory page within the memory, including, for each guest-physical memory page in the first set of guest-physical memory pages, mapping a corresponding guest-physical address (GPA) to a corresponding HPA;
• associate the first set of guest-physical memory pages with a virtual non-uniform memory access (NUMA) node that includes a compute resource;
• identify a second set of guest-physical memory pages within the VM address space to be backed by host-virtual addresses (HVAs);
• map each guest-physical memory page in the second set of guest-physical memory pages to a different HVA, including, for each guest-physical memory page in the second set of guest-physical memory pages, mapping a corresponding GPA to a corresponding HVA;
• associate the second set of guest-physical memory pages with a NUMA node that lacks any compute resource;
• and
• during an execution phase of the VM at the VM host computer system, process an intercept based on the VM accessing a GPA that is mapped to an HVA, including mapping the HVA to an HPA.
