Abstract
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.
