Embodiment Construction

[0018] As can be seen from the background art, in order to solve the migration problem of virtual machine disks, the disk data obtained from the source platform is usually placed in a temporary storage file, and then the disk data stored in the temporary file is converted into the file of the destination platform. format, and finally upload the temporary file of the converted format to the destination platform to complete the disk migration. Although disk migration can be achieved through the above temporary storage and format conversion process, because the amount of data on the disk is usually large, it will take a lot of temporary storage space to run. Therefore, how to reduce the storage overhead and time overhead during the disk migration process It is an urgent problem that needs to be solved.

[0019] In order to solve the above problem, an embodiment of the present application provides a cross-cloud migration method for virtual machine disks. The method is applied to a...

Abstract

The embodiment of the invention relates to the technical field of cloud computing, and discloses a virtual machine disk cross-cloud migration method, electronic equipment and a storage medium, the method is applied to a data migration service, and the data migration service is used for migrating source virtual machine disk data on a source platform to a target virtual machine disk file on a target platform. The method comprises the following steps: S1, obtaining at least one data block in a source virtual machine disk from a source platform; s2, according to a data storage structure of a target virtual machine disk file on the target platform, determining a storage position of at least one currently acquired data block in the target virtual machine disk file; s3, writing at least one currently acquired data block into the storage position; and S3, repeatedly executing the steps S1 to S3 until all the data blocks in the source virtual disk are written into the target virtual machine disk file. Disk migration is realized in a stream form, temporary storage space is saved, and storage overhead and time overhead are greatly saved.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, and in particular, to a method for migrating virtual machine disks across clouds, an electronic device and a storage medium. Background technique [0002] In the scenario of virtual machine migration across clouds, the migration of virtual machine disks is the most important step. Since the virtualization technologies of different cloud platforms are different, the formats of the disk files loaded by the virtual machine disks of each platform are different. Therefore, the migration of virtual machine disks across clouds often involves data migration and format conversion. [0003] For example, the vmware platform uses the vmdk format disk file, and the openstack platform uses the raw format disk file. In the prior art, in the scenario of migrating a virtual machine from the vmware platform to the openstack platform, first download the source vmdk file (source disk file) to the l...
