Embodiment 1

[0063] The inventor of the present application proposes that a virtual machine migration detection mechanism can be preset as a pre-detection condition for virtual machine migration, so as to reduce and avoid possible faults caused by virtual machine invalid migration and failed migration. Based on this idea, this embodiment provides a detection method for virtual machine migration in a virtualization platform, such as figure 1 As shown, including the following operations:

[0064] When the virtual machine is migrating, determine whether the migration of the virtual machine spans the host host;

[0065] If the migration of the virtual machine spans the host host, it is judged that the preset first migration condition is met, and the migration operation is performed;

[0066] The first migration condition includes any one or more of the following conditions:

[0067] The virtual machine does not use any physical devices on the host host, where the physical devices on the host...

Embodiment 2

[0107] This embodiment provides a detection device for virtual machine migration, which mainly includes the following parts.

[0108] The judging unit, when the virtual machine is migrated, determines whether the migration of the virtual machine spans the host host;

[0109] The migration unit performs a migration operation when it judges that the preset first migration condition is satisfied when the migration of the virtual machine crosses the host host;

[0110] Specifically, the first migration condition may include any one or several of the following conditions:

[0111] The virtual machine does not use any physical device on the host machine (for example, cdrom, USB device, raw disk, physical network card, CPU of the host machine bound to the vcpu of the virtual machine, etc.);

[0112] The migrated target host resources meet the virtual machine resource requirements;

[0113] The CPU architecture type of the virtual machine is lower than that of the target host after ...

Abstract

The invention discloses a detection method for virtual machine migration and equipment for virtual machine migration, and relates to the technical field of stack virtualization. The detection method for virtual machine migration includes the following steps that when a virtual machine is migrated, whether the virtual machine crosses a host in the migration process or not is determined; if the virtual machine crosses the host in the migration process, migration is performed when it is judged that a preset first migration condition is met. Faults which are likely to be caused by invalid migration and failure migration of the virtual machine are reduced and avoided, and the success rate and reliability of virtual machine migration are improved.

Description

technical field [0001] The invention relates to the technical field of openstack (cloud computing management platform) virtualization, in particular to a detection method and equipment for virtual machine migration in a virtualization platform. Background technique [0002] With the application of virtualization technology more and more widely, in various fields, virtual machines are gradually replacing physical machines to run some services. When more and more businesses are running on virtual machines, people's requirements for virtual machines are also increasing. High, including the migration of the virtual machine, and the current virtual machine migration technology always has the situation that the migration is invalid or fails. Contents of the invention [0003] This article provides a virtual machine migration detection method and device, which can solve the problems of invalid migration and failed migration that occur during the existing virtual machine migration...
