Abstract

The present invention discloses a single root_I / O virtualization (SR_IOV)-based virtualization implementation method. The method comprises the steps of enabling an IOMMU function or a TV-D function in a basic input output system (BIOS), and enabling an SR_IOV function in the BIOS; modifying startup items of a kernel, and enabling the IOMMU function in the kernel; allocating a virtualization function (VF) for a physical network adapter; and allocating the VF to a virtual machine to use. Through adoption of the method, the virtual machine can better use the I / O.

Description

technical field [0001] The invention relates to the technical field of virtualization, in particular to an SR_IOV-based virtualization implementation method. Background technique [0002] With the widespread application of cloud computing, the changes in I / O performance of virtualization technology are becoming more and more prominent. SR-IOV and Sharing Specification (Single Root I / O Virtualization, single root I / O virtualization) technology A physical device can be assigned to multiple virtual machines, which improves the utilization of physical resources. Each SR-IOV device has a physical function PF. PF can create VF through registers. Once SR-IOV is enabled in PF , you can access the PCI configuration space of each VF through the bus, device and function numbers of the PF. Each VF has its own independent configuration space and complete base address register. The Hypervisor maps the configuration space actually used by the VF to the configuration space that the client ...
