  The next-generation Industrial Internet of Things (IIoT) inherently requires
smart devices featuring rich connectivity, local intelligence, and autonomous
behavior. Emerging Multiprocessor System-on-Chip (MPSoC) platforms along with
comprehensive support for virtualization will represent two key building blocks
for smart devices in future IIoT edge infrastructures. We review representative
existing solutions, highlighting the aspects that are most relevant for
integration in IIoT solutions. From the analysis, we derive a reference
architecture for a general virtualization-ready edge IIoT node. We then analyze
the implications and benefits for a concrete use case scenario and identify the
crucial research challenges to be faced to bridge the gap towards full support
for virtualization-ready IIoT nodes
