Disclosed in the present application is a resource overcommitting scheduling method based on GPU virtualization. The method comprises: step one, creating a GPU virtual machine; step two, setting GPU parameter information of the virtual machine; step three, scheduling GPU resources on the basis of the GPU parameter information of the virtual machine, and selecting a sequence of available GPU hosts; step four, during scheduling, performing scheduling calculation on the basis of stored GPU information; and step five, on the basis of comprehensive scoring performed by a GPU host weighing device and a GPU model weighing device, selecting a GPU host and a GPU model. In the present application, GPU overcommitting is further performed on GPU resources which have been subjected to GPU full virtualization, GPU information and an overcommitting parameter are stored according to a formulated format, and idle GPU resources are allocated to a virtual machine by means of a scheduling algorithm, so as to utilize the GPU resources to the maximum extent; the total number of virtual GPU resources is calculated by means of an overcommitting coefficient, and the real available quantity of GPUs is taken into account, so as to select a list of available hosts; and GPU host weighing and GPU model weighing are then used, so as to comprehensively select an optimal host and an optimal GPU model.

The invention provides a multi-tenant system of a home broadband cloud gateway and a configuration planning method of the multi-tenant system, and relates to the technical field of broadband, the system comprises a physical server which carries a plurality of fully virtualized vCPEs; each vCPE corresponds to a VM (virtual machine) of one entity; each vCPE is used for bearing a plurality of para-virtualized vGWs (Virtual Gateways); each vGW corresponds to a VirtIO port, a VRF (Virtual Radio Frequency) and a home wide user; and a VirtIO port corresponding to each vGW is bound with a VRF (Virtual Radio Frequency), and the VRF is used for realizing isolation of home wide users in each vGW.

The invention discloses an I / O real-time response method based on an ARM microkernel Hypervisor, the Hypervisor maintains a binary counter table for each vCPU, the binary counter table comprises a scheduling mode identifier corresponding to each I / O task and a binary scheduling state counter, when an external device triggers an I / O event, the Hypervisor judges whether a target vCPU is in an idle state, if yes, the priority of the target vCPU is improved, operation is preempted, and if not, the target vCPU is in the idle state; and otherwise, acquiring a scheduling mode identifier of the target I / O task in the target vCPU, adopting a conventional scheduling mode or a Boosting scheduling mode according to the scheduling mode identifier, and realizing scheduling mode switching according to the value of the scheduling state counter in each scheduling mode. By means of support provided by an ARMv8 system structure, an adaptive scheduling mode switching mechanism based on the historical task scheduling condition is provided in a full virtualization mode, it is ensured that I / O tasks can still be scheduled in time between high-priority tasks, and the I / O response speed is increased.

The application provides a log implementation method in a Hypervisor / virtualization environment, and relates to the technical field of operating system virtualization, and comprises the following steps: outputting a log by operating physical debugging hardware in a starting stage by the Hypervisor, and closing a driver before starting an SOS, and temporarily storing the log in a kernel buffer area of the driver; after transferring all the ownership of the hardware to the SOS, reading and outputting the temporarily-stored log of the Hypervisor by the kernel of the SOS through shared memory; in an early console stage of a UOS, intercepting and converting a hardware access operation of the UOS by the Hypervisor through full virtualization technology, and storing the log in a buffer area; after the early console stage of the UOS, switching to a semi-virtualization channel, and sending the log to a user space back-end process of the SOS.
