Efficient virtualization on embedded power architecture® platforms
Aashish Mittal, Dushyant Bansal, Sorav Bansal, Varun Sethi · 2013
Power Architecture® processors are popular and widespread on embedded systems, and such platforms are increasingly being used to run virtual machines. While the Power Architecture meets the Popek-and-Goldberg virtualization requirements for traditional trap-and-emulate style virtualization, the performance overhead of virtualization remains high. For example, workloads exhibiting a large amount of kernel activity typically show 3-5x slowdowns over bare-metal.
