NVDIMMs are new type of ultra fast storage that's plugged into DIMM slot and can hold the stored info throughout reboots. After all, NV stands for non-volatile. In virtualization world, this has an awesome advantage - less VM_EXITs on 'disk' IO. https://nvdimm.wiki.kernel.org/ Currently, there is no NVDIMM namespace support. I think qemu does not support it either.
