Embodiment Construction

[0026] The method provided by the embodiment of the present invention may be applied to a virtualized interface device, and the virtualized interface device may specifically be a virtualized network card, a virtualized graphics card, a virtualized memory card, and the like. The virtualization interface device supports virtualization technology. For example, the virtualized network card may specifically be a network card that supports Single-Root I / O Virtualization (SR-IOV). In the embodiment of the present invention, a virtualized interface device is taken as a virtualized Peripheral Component Interconnect Express (PCIE) device as an example for description.

[0027] In a typical virtual machine application architecture, such as figure 1 As shown, multiple virtual machines (Virtual Machine, VM for short) can run on one physical host. The hardware of a general physical host mainly includes: part of the hardware related to running virtual machines, such as CPU, memory, hard disk, ...

Abstract

The invention discloses a fault recovery method and device, relates to the field of computer technologies, and aims at solving the problem that services of all virtual machines of a physical host to which a network card chip belongs are influenced when the network card chip is recovered in a power-off reset manner. The method comprises that a target processing core is determined, and the target processing core is the processing core, which has a fault, among multiple processing cores; a target virtual interface is determined, a target service message is sent to the target processing core or received from the target processing core via the virtual interface, the target service message is the service message which is processed by the target processing core when the fault occurs; resources associated with the target virtual interface in virtualized interface equipment are released; and the target virtual interface and the target processing core are reset.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a failure recovery method and device. Background technique [0002] In order to support various network services in the future, the network card chip is gradually softened by integrating many small processing cores in the dedicated integrated circuit inside the network card chip. These small processing cores can complete the processing of different network services with various hardware acceleration engines. [0003] Due to the small processing core resources and small storage space, only a small amount of code can be run, and no operating system (OS) is installed. Therefore, it is impossible to implement fault isolation and protection through a huge OS and related complicated memory management mechanism like a central processing unit (Central Processing Unit, CPU for short). [0004] Faults caused by software are much more likely than those caused by pure hardware, and faults...
