Problems solved by technology

However, in the case of multiple cell deployments, since the database services are mostly independent and the contents in the data tables are different, it is easy to cause the virtual machine to fail to migrate across cells, which will adversely affect the actual operation and maintenance.

Embodiment Construction

[0050] The cell includes a default cell0, which is used to store virtual machines that fail to be created or whose status is error; according to the scale of the actually deployed cluster, the nova-compute service and nova-conductor service are distributed to different cells.

[0051] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0052]The present invention provides a method for migrating a virtual machine across cells in openstack, locates the source cell and the destination cell of the virtual machine migration, and constructs corresponding migration tasks according to different migration types of the virtual machine.

[0053] Determine whether the virtual machine is hot migrated or cold migrated,

[0054] If the cold migration of...

Abstract

The invention discloses a method for migrating a virtual machine across a cell by openstack, and relates to the technical field of cloud computing virtual machines. The method comprises the followingsteps: positioning a source cell and a destination cell of virtual machine migration, constructing corresponding migration tasks according to different migration types of the virtual machine, judgingwhether the virtual machine performs thermal migration or cold migration, if the virtual machine performs cold migration, performing preparation operation in the destination cell, updating the state of the virtual machine, and judging whether the original virtual machine and the current virtual machine are in the same cell or not; determining whether to update or operate the databases of the source cell and the destination cell, if the virtual machine is subjected to thermal migration, operating on the novacomput of the destination cell, and determining whether to update or operate the databases of the source cell and the destination cell by judging whether the original virtual machine and the current virtual machine are in the same cell.

Description

technical field [0001] The invention discloses a method for migrating a virtual machine, relates to the technical field of cloud computing virtual machines, and in particular relates to a method for migrating a virtual machine across cells in openstack. Background technique [0002] nova is a lifecycle management component in openstack for virtual machine creation and deletion. Virtual machine hot migration is a function of online migration of the host where the virtual machine resides. During the migration process, the memory of the virtual machine will be migrated from the current computing node to another On a computing node, non-shared disks (such as local disks, etc.) can also be copied during the migration process. The migration process only temporarily suspends the virtual machine in the last step. The program is insensitive, and the virtual machine can still run normally before and after the migration. [0003] Cell is the deployment optimization of the nova project...
