Abstract: The present application discloses a virtual machine migration method and apparatus. A specific implementation of the method includes: receiving a migration request for migrating a virtual machine, wherein to-be-migrated data of the virtual machine comprises local data locally stored and shared data accessible by the virtual machine at a plurality of locations; determining migration operations respectively corresponding to the local data and the shared data in response to the migration request; and executing the migration operations corresponding to the local data and the shared data, to complete migration of the virtual machine. This implementation achieves the migration of a virtual machine with a hybrid storage mode, that is, a storage mode in which the data to be migrated includes both local data and shared data.

Abstract: A method and apparatus for starting a virtual machine. A specific implementation of the method comprises: acquiring, by a physical machine, a mirror image file required for starting a to-be-started target virtual machine from a distributed block storage system, in response to an entered instruction to start the target virtual machine; and starting the target virtual machine by using the mirror image file. The mirror image file required for starting the virtual machine is stored in the cloud-based distributed block storage system, and a virtual disk is mapped to the physical machine. When the physical machine needs to start the virtual machine, the mirror image file required for starting the virtual machine is acquired from the cloud-based distributed block storage system by reading the virtual disk.

Abstract: The present disclosure discloses a method and apparatus for inserting a disk. The method comprises: detecting whether a to-be-inserted disk has a drive letter identifier, wherein the drive letter identifier is acquired by a server through: acquiring a universally unique identifier of the disk; querying a correspondence between the universally unique identifier and a device name, acquiring the device name of the disk, analyzing the device name of the disk to generate a drive letter value of the disk, and generating a drive letter identifier for the disk; acquiring the drive letter value in response to detecting the disk identifier; determining whether the device name associated with the drive letter value is allocated to a different disk; and defining the device name of the disk based on the drive letter value so as to insert the disk if the device name is not allocated to the different disk.

Abstract: A method, an apparatus, a device, and a computer readable storage medium for starting a virtual machine are provided. The method includes generating a disk snapshot for a first piece of data on a virtual disk of a first virtual machine. The method further includes starting running a second virtual machine based on identifier information of the first virtual machine and address information of the disk snapshot, such that the first piece of data is copied to a virtual disk of the second virtual machine. The method further includes pausing running the second virtual machine, in response to initialization of an operating system on the started second virtual machine being completed, for restoring the first virtual machine when the first virtual machine is unavailable.

Abstract: A method and apparatus for creating a system disk snapshot of a virtual machine comprises: receiving an instruction for creating a snapshot of a virtual machine; determining existence of a power-on state; renaming a top file in a system disk in response to the received instruction if the power-on state exists; creating a new top file in response to renaming the top file, directing dependency of the new top file to the renamed top file and opening the new top file; determining whether a preceding snapshot is created successfully; using the renamed top file as a first snapshot file if the preceding snapshot is successful; and uploading the first snapshot file to a file management server. Accordingly, when a system disk snapshot is created in a power-on state, the snapshot may be created without stopping the virtual machine, thereby reducing requirements for data back up, storage space, and network bandwidth.
