The cloud platform provided by the invention particularly refers to an IaaS cloud platform, and various cloud computing infrastructure software manufacturers in the IaaS cloud platform, such as VMware, Microsoft, IBM, OpenStack and the like, exist. Virtualization technology is the core technology of cloud platforms.

In a specific implementation, migration of a virtual machine is often required between two heterogeneous cloud platforms, and the virtual machine in the cloud platform includes a single disk or multiple disks. In the prior art, manual configuration needs to be executed for migration of a single-disk virtual machine. The target cloud platform operating system and the source cloud platform disk file format are not completely consistent. Firstly, environmental parameters need to be collected, and the format of a disk file is converted according to the mode of a target cloud platform.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
The core of the invention is to provide an automatic virtual machine migration system and method between heterogeneous cloud platforms, which are used for reducing the tedious work brought by manual operation.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a structural diagram of an automatic virtual machine migration system between heterogeneous cloud platforms according to an embodiment of the present invention. As shown in fig. 1, the system for automatically migrating virtual machines between heterogeneous cloud platforms includes:
the determining unit 10 is configured to determine whether a format of a disk file of a source virtual machine in a source cloud platform matches a format supported by a target cloud platform.
In a specific implementation, the determining unit 10 specifically includes: an obtaining module 100, configured to obtain a format of a disk file and a format supported by a target cloud platform; the determining module 101 is configured to determine whether the format of the disk file matches a format supported by the target cloud platform. It is understood that the format of the acquired disk file is obtained from the suffix name of the disk file.
The first importing unit 11 is configured to import the disk file into the target cloud platform when the format of the disk file matches the format supported by the target cloud platform.
And a format conversion unit 12, configured to, in a case that the format of the disk file does not match the format supported by the target cloud platform, convert the format of the disk file into the format supported by the target cloud platform.
If the format of the disk file of the source virtual machine is not matched with the format supported by the target cloud platform, the format of the disk file of the source virtual machine needs to be modified, otherwise, the disk file is directly imported into the target cloud platform. In a specific implementation, if the format of the disk file of the source virtual machine does not match the format supported by the target cloud platform, the format of the disk file needs to be modified, and the operating system of the target cloud platform and the disk interface driver of the source virtual machine need to be updated, which is specifically described below.
The operating system matching unit 13 determines, for a case that the source virtual machine includes a single disk or multiple disks, an update state of the operating system of the target cloud platform and an update state of the disk interface driver of the source virtual machine.
In a specific implementation, the operating system matching unit 13 specifically includes:
the first determining module 130 is configured to determine whether the source virtual machine occupies multiple disks.
The second judging module 131 is configured to, when the source virtual machine occupies multiple disks, judge whether a kernel of an operating system of the source virtual machine supports running of the multiple disks in the target cloud platform;
the updating module 132 is configured to mount a disk occupied by the operating system of the source virtual machine on the basis of a disk interface driver supported by the target cloud platform and update the kernel of the operating system of the target cloud platform, when the kernel of the operating system of the source virtual machine does not support the operation of multiple disks in the target cloud platform;
a third determining module 133, configured to determine whether a disk interface driver of an operating system of the source virtual machine supports a disk interface driver required by the target cloud platform when the source virtual machine occupies a single disk, or the source virtual machine occupies multiple disks, and the operating system of the source virtual machine supports multiple disks to run in the target cloud platform, or a kernel of the operating system of the target cloud platform is updated: if yes, triggering a second import unit 14;
the driver installation module 134 is configured to inject a disk interface driver required by the target cloud platform into the operating system of the source virtual machine under the condition that the disk interface driver of the operating system of the source virtual machine does not support the disk interface driver required by the target cloud platform.
It can be understood that, after the disk file of the source virtual machine is modified because the format of the disk file is not matched with that supported by the target cloud platform, the operating systems of the source virtual machine and the corresponding disk interface drivers need to be correspondingly detected and judged. First, the source virtual machine may occupy a single disk or a plurality of disks, and if the determination result of the first determining module 130 is that a single hard disk is occupied, the third determining module 133 determines directly without updating the operating system of the target cloud platform. If the judgment result of the first judgment module 130 is that a plurality of hard disks are occupied, the second judgment module 131 is required to further judge whether the kernel of the operating system of the source virtual machine supports the operation of a plurality of disks in the target cloud platform.
It can be understood that if the kernel of the operating system of the source virtual machine does not support the running of multiple disks in the target cloud platform, the target cloud operating system cannot run even if the modified disk file is imported into the target cloud operating system. In this embodiment, if the kernel of the operating system of the source virtual machine does not support the operation of multiple disks in the target cloud platform, the updating module 132 mounts the disk occupied by the operating system of the source virtual machine based on the disk interface driver supported by the target cloud platform, and updates the kernel of the operating system of the target cloud platform. In other words, each disk interface driver is searched in the target cloud platform, a suitable disk interface driver is selected from the plurality of disk interface drivers to mount a disk, after mounting, the target cloud platform can identify a new disk, that is, multiple disks of the kernel of the operating system of the source virtual machine can be supported to run, and then the update module 132 updates the kernel of the operating system of the target cloud platform.
It can be understood that the formats of the disk files of the source virtual machine in this embodiment include a vmdk format, a qcow2 format, a raw format, a cow format, a vdi format, a vhd format, a voa format, a ovf format, and the like; the interfaces in the disk interface drive include an IDE interface, a SATA interface, a SCSI interface, an SAS interface, an ISCSI interface, or a VIRTIO interface.
The second importing unit 14 is configured to import the modified disk file into the target cloud platform according to the update state of the operating system of the target cloud platform and the update state of the disk interface driver of the source virtual machine.
It can be understood that the automatic virtual machine migration system between heterogeneous cloud platforms in this embodiment may operate as a single system, may be disposed on the source cloud platform side, or may be disposed on the target cloud platform side. The plurality of disks described in this embodiment refer to all cases except a single disk, that is, include two disks and more than two disks.
In the automatic migration system of the virtual machine between the heterogeneous cloud platforms, the automatic migration of the virtual machine is realized by using the first import unit, the format conversion unit, the operating system matching unit and the second import unit of the judgment unit, so that the workload of manual operation is greatly reduced, and the update state of the operating system of the target cloud platform and the update state of the disk interface driver of the source virtual machine can be determined according to the number of disks included in the source virtual machine, thereby realizing the migration of the virtual machine including a single disk or multiple disks.
