An online migration method and system for a bare metal server, where a first hardware card receives a migration command for a first bare metal server, and where the first hardware card is inserted into the first bare metal server. The first hardware card notifies, based on the migration command, the first bare metal server to start a virtual machine manager in the first bare metal server, where the virtual machine manager records first dirty memory page location information that is for memory of the first bare metal server and that is generated by the first bare metal server, and sends the first dirty memory page location information to the first hardware card. The first hardware card online migrates a dirty memory page of the first bare metal server to a second bare metal server based on the first dirty memory page location information.

A data transmission method includes: obtaining information required for performing an acceleration operation in a virtual input/output ring of a target virtual accelerator, where the information required for performing the acceleration operation uses a predefined data structure, and the data structure occupies one entry of the virtual input/output ring of the target virtual accelerator; determining, according to the information required for performing the acceleration operation, information that can be recognized by the hardware accelerator; and sending the information that can be recognized by the hardware accelerator to the hardware accelerator, where the hardware accelerator is configured to obtain to-be-accelerated data according to the information that can be recognized by the hardware accelerator and perform the acceleration operation on the to-be-accelerated data.

Data transmission method and apparatus

A data transmission method and apparatus are disclosed, and applied to a daemon process on a host machine. The method includes: obtaining information required for performing an acceleration operation in a virtual input/output ring of a target virtual accelerator, where the information required for performing the acceleration operation uses a predefined data structure, and the data structure occupies one entry of the virtual input/output ring of the target virtual accelerator; determining, according to the information required for performing the acceleration operation, information that can be recognized by the hardware accelerator; and sending the information that can be recognized by the hardware accelerator to the hardware accelerator, where the hardware accelerator is configured to obtain to-be-accelerated data according to the information that can be recognized by the hardware accelerator and perform the acceleration operation on the to-be-accelerated data. The method and apparatus can improve data packet transmission efficiency.

Technologies related to automatic account login are disclosed. In an implementation, a request from a user for logging in to an account of a second website associated with an account of the first website is received. The account of the first website is determined logged in to by the user. An automatic login token is generated based on one or more token generation rules agreed to by the second website for performing automatic login, and an automatic login link is generated and sent to the user, where the automatic login link includes the automatic login token, the automatic login link allowing the user to send an automatic login request that includes the automatic login token, and wherein the automatic login token is verified based on the one or more token verification rules to allow the user to automatically log in to the account of the second website.

Automatic login method and device between multiple websites

Embodiments of the present invention provide a terminal registration method, device, and system, and relate to the field of communications technologies, so as to ensure that a terminal determines in time whether registration is successful, and save network resources. The method includes: starting, by an access point device, monitoring on a monitored resource when the access point device receives an access request message sent by a terminal; and after the terminal sends a registration request message to a database, if the access point device receives, when the monitored resource monitored by the access point device does not reach a monitoring threshold, a registration response message sent by the database, stopping the monitoring on the monitored resource. Embodiments of the present invention are used for terminal registration.
