Abstract

The invention discloses a virtual machine migration method, device and equipment and a computer readable storage medium, and the method comprises the steps: obtaining the current host resource utilization rate of a target host before the virtual machine is migrated to the target host from a source host; judging whether the host resource utilization rate reaches a resource utilization rate threshold or not; and if yes, determining that the current host resource of the target host cannot be migrated by the virtual machine, and refusing to realize the migration of the virtual machine, and if not,determining that the current host resource of the target host can be migrated by the virtual machine, and starting to execute the migration of the virtual machine. In this way, the situation that migration of the virtual machine fails due to the fact that host resources of the target host cannot support migration of the virtual machine in the prior art is avoided, and then the migration success rate of the virtual machine is increased.

Description

technical field [0001] The present invention relates to the technical field of virtual machine migration, and more specifically, to a virtual machine migration method, device, equipment, and computer-readable storage medium. Background technique [0002] Online migration of virtual machines, also known as live migration, refers to the migration of virtual machines between different physical hosts while ensuring the normal operation of services on the virtual machine. The logical steps are almost identical to those of offline migration. The difference is that in order to ensure the availability of virtual machine services during the migration process, there is only a very short downtime during the migration process. [0003] Specifically, after the migration of the virtual machine starts, the virtual machine of the source host is still running, and the virtual machine of the destination host has not been started; the migration passes through a cycle, sending the memory data o...
