Abstract: A data processing method for a network adapter includes the network adapter that obtains a first input/output (I/O) command. The first I/O command instructs to write data stored in a local server to at least one remote server, and the first I/O command includes address information and length information that are of the data and that are stored in the local server. The network adapter splits the data based on the address information and the length information to obtain a plurality of groups of address information and length information. The network adapter obtains, from the local server based on the groups of address information and length information, data corresponding to the groups of address information and length information, and sends the data to the at least one remote server.

Abstract: 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.
Abstract translation: 虚拟机实时迁移方法和服务器，以解决在SR-IOV技术情况下无法实现虚拟机的实时迁移的问题。 根据本发明实施例中的虚拟机实时迁移方法和服务器，通过设置脏写入标志，待迁移虚拟机的虚拟PCIE设备对接收到的数据执行至少一次读写操作 ; 要迁移的虚拟机的虚拟机管理器可以识别数据的变化并将改变的数据迁移到目的地虚拟机，从而解决现有技术中在虚拟机实时迁移过程中不能迁移数据的问题 因为数据通过虚拟PCIE设备，但虚拟机管理器无法察觉数据。

Abstract: In a data access method, a processor of a host converts a first descriptor recognized by a virtual machine interface card of the virtual machine into a second descriptor recognized by a physical interface card of the host. The first descriptor includes a virtual machine physical memory address and a data length of accessible data. The physical interface card of the host obtains, based on the second descriptor, a physical address that is in a memory and to which the virtual machine physical memory address is mapped, and accesses the accessible data according to the physical address in the memory.

Abstract: A data processing method includes sending, by a network interface card of a first device, a request packet to a second device. The request packet is used to request to read data in a destination storage area of the second device. The network interface card receives a response packet that is sent by the second device in response to the request packet. The response packet includes the data. The network interface card initiates, based on the response packet, direct memory access to a storage address to write the data into a memory area to which the storage address points. The first data does not need to be cached in a memory of the network interface card. Bandwidth resource usage and storage space usage of the memory of the network interface card can be reduced.
