Abstract

The invention relates to a method for thermal migration of a virtual machine and a server and aims to solve the problem that the thermal migration of the virtual machine cannot be realized in an SR-IOV (Single-Root I / O Virtualization) technical scene. According to the method for thermal migration of the virtual machine and the server of the embodiment, a dirty-writing mark is set so that virtual PCIE (Peripheral Component Interface Express) equipment of a to-be-migrated virtual machine performs at least one read-write operation on received data; a virtual machine manager of the to-be-migratedvirtual machine can identify data change and migrates the changed data into a target virtual machine. Therefore, the problem in the prior art of incapability of data migration caused by the fact thatthe data are enabled to pass through the virtual PCIE equipment in a process of thermal migration of the virtual machine and cannot be sensed by the virtual machine manager is solved.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method for live migration of a virtual machine, a method for processing memory data of a virtual machine, a server and a virtual machine system. Background technique [0002] SR-IOV (Single-Root I / O Virtualization, single-root IO virtualization) is an IO virtualization technology that can be virtualized on a physical PCIE (Peripheral Component Interconnection Express English, fast peripheral component interconnection standard) device. Create multiple virtual PCIE devices. Virtual PCIE devices can only be configured and managed through the original physical PCIE device. Each virtual PCIE device can have independent interrupts and DMA (DirectMemory Access, direct memory access), so that the virtual machine can The physical PCIE device is directly accessed through the virtual PCIE device without the intervention of a VMM (Virtual Machine Monitor, virtual machine monit...
