NVDIMM is a new feature on Intel Skylake Servers that provides the high-performance and high-density persistent memory. Although NVDIMM can be accessed via a way similar to the normal memory load/store, a sophisticated driver is required for device detection and maintenance. These characters as well as its usage model bring challenges to provide NVDIMM to guests in Xen. In this presentation, I'll introduce the primary challenges and the proposed approaches to address them.
