A virtual machine migration method and apparatus are provided, which pertain to the field of computer technologies. The method includes: obtaining a first mapping relationship, pre-stored on a source cloud platform, between a source virtual machine (VM) and a specified user when data in the source VM is migrated to a destination VM; configuring the destination VM and the specified user to form a second mapping relationship according to the obtained first mapping relationship; and storing the second mapping relationship on a destination cloud platform. Therefore, a user that has registered on the source VM can log in to a virtual desktop corresponding to the destination VM and does not need to register on the destination VM again.
