摘要： Embodiments of the present invention provide a virtual machine live migration method and a server, to resolve a problem that live migration of a virtual machine cannot be implemented in an SR-IOV technology scenario. According to the virtual machine live migration method and the server in the embodiments of the present invention, by setting a dirty write flag, a virtual PCIE device of a to-be-migrated virtual machine performs at least one read and write operation on received data; a virtual machine manager of the to-be-migrated virtual machine can identify a change in the data and migrate changed data to a destination virtual machine, thereby resolving a problem in the prior art that data cannot be migrated during a virtual machine live migration process because the data passes through the virtual PCIE device but the virtual machine manager cannot perceive the data.

摘要： Embodiments of the present invention provide a switch board of a blade server, a port configuring method thereof, and a blade server. The switch board includes a port configuring unit and at least one port, where the port configuring unit is configured to divide the switch board into more than one virtual sub-switch-board, allocate the port to the virtual sub-switch-boards, and configure each port of each virtual sub-switch-board to a first-type port or a second-type port, where the first-type port and the second-type port have different bandwidth; and the port is configured to connect a server blade according to a configuration on the port configuring unit. The embodiments of the present invention further provide a corresponding port configuring method and a blade server. The technical solutions of the present invention can meet a requirement for flexible port bandwidth configuration.

摘要： A method for managing a memory of a virtual machine, a physical host, a PCIE device and a configuration method thereof, and a migration management device are provided, and relate to the field of virtual machines. The method includes: allocating, by a virtual machine, a memory to at least one service carried on a PCIE device (101), where the memory allocated to each service includes multiple memory blocks, each of the multiple memory blocks is used to save working information of a corresponding service, and each memory block is a section of memory space in which guest physical addresses are consecutive; generating, by the virtual machine, a base address table BAT and a chip logic address table CLAT according to the memory allocated to each service (102), where the BAT includes a CLAT entry base address corresponding to each service, and the CLAT includes a first address of each memory block; and sending, by the virtual machine, an address of the BAT and a function number corresponding to the virtual machine to the PCIE device (103). The PCIE device is configured to: record a correspondence between the address of the BAT and the function number, and obtain, from the virtual machine, working information of a service according to the correspondence between the address of the BAT and the function number.
