摘要: A method for migrating virtual machines between hypervisors is disclosed. Initially, metadata describing a virtual machine are automatically scanned and parsed. The structure of the metadata of a source virtual machine are automatically analyzed. Elements of this structure are mapped to corresponding entries of a target virtual machine. A target metadata descriptor to be used as part of the target virtual machine is generated. A predefined layout description of the data stored in a file system image of the source virtual machine read. A predefined layout description of the data to be stored in a file system image to be used at the target virtual machine is also read. The data are extracted from the source virtual machine. A template of a file system image for the target virtual system is generated. Storage space corresponding to the target virtual machine is allocated, and the extracted data are inserted into the allocated storage space.
