Abstract: A soft partitioning system for allowing multiple virtual system environments to execute on a single platform may include I/O service partitions (IOSPs). The IOSPs operating in a separate virtual memory space on the platform and service disk and network requests from multiple guests. The IOSPs provide translation from virtual addresses to physical addresses such that from the point of view of the guest the virtual addresses used by the guest appear to be physical addresses. The IOSP may be implemented in a Linux kernel. The address space of the IOSP may be extended to include DMA memory sections such that the Linux kernel does not include all of the guest's memory. The IOSP may operate on hardware that does or does not support virtualization technology for directed I/O,

Abstract translation: 用于允许多个虚拟系统环境在单个平台上执行的软分区系统可以包括I / O服务分区（IOSP）。 IOSP在平台上独立的虚拟内存空间中运行，服务磁盘和多个来宾的网络请求。 IOSP提供从虚拟地址到物理地址的转换，使得从guest虚拟机的角度来看guest虚拟机使用的虚拟地址看起来是物理地址。 IOSP可以在Linux内核中实现。 IOSP的地址空间可以扩展到包含DMA内存部分，以便Linux内核不包含所有客户的内存。 IOSP可以在支持或不支持针对定向I / O的虚拟化技术的硬件上运行，
