Proposal of Software-based Logical Partitioning in x86 Machine - Hiraku Toyooka, Hitachi

Sign up or log in to save this event to your list and see who's attending!


In this presentation, we propose a mechanism which partitions x86 machine resources into some logical instances and run guest OSes on those instances in parallel with host Linux. This mechanism directly assigns a subset of CPUs, physical memory areas and I/O devices to a guest OS when it boots. The instance’s CPUs are unplugged from host Linux when the guest OS runs. As a result, we can run the guest OS with less overhead and noise than that in existing virtualization technology such as KVM. This mechanism is useful for consolidation of real-time systems. It is also applicable to server appliances which have separated sub-OSes to control specific hardware. I’m currently implementing this mechanism into Linux using remoteproc framework.

The target audience for this presentation is developers who interested in virtualization and real-time systems.
