Abstract: Examples may include techniques for persistent memory virtualization. Persistent memory maintained at one or more memory devices coupled with a host computing device may be allocated and assigned to a virtual machine (VM) hosted by the host computing device. The allocated persistent memory based on a file based virtual memory to be used by the VM. An extended page table (EPT) may be generated to map physical memory pages of the one or more memory devices to virtual logical blocks of the file based virtual memory. Elements of the VM then enumerate a presence of the assigned allocated persistent memory, create a virtual disk abstraction for the file based virtual memory and use the EPT to directly access the assigned allocated persistent memory.
