Slides posted for "Using NVDIMM under KVM" talk

I gave a talk on NVDIMM persistent memory at FOSDEM 2017. QEMU has gained support for emulated NVDIMMs and they can be used efficiently under KVM.

Applications inside the guest access the physical NVDIMM directly with native performance when properly configured. These devices are DDR4 RAM modules so the access times are much lower than solid state (SSD) drives. I'm looking forward to hardware coming onto the market because it will change storage and databases in a big way.

This talk covers what NVDIMM is, the programming model, and how it can be used under KVM. Slides are available here (PDF).
