Abstract

The invention discloses a virtual machine migration method, device and system and a storage medium. The method comprises the following steps: acquiring a memory management mode of target equipment; comparing the memory management mode of the target device with the memory management mode of the source device; determining a creation mode of a target virtual machine running on the target equipment according to a comparison result; and migrating the memory and the device state of the source virtual machine running on the source device to the target virtual machine created according to the creation mode. The technical problem that live migration of the virtual machine cannot be carried out due to different memory management modes on different host machines is solved.

Description

technical field [0001] The present application relates to the field of virtual machine live migration, and in particular, relates to a virtual machine migration method, device, system, and storage medium. Background technique [0002] During live migration of a virtual machine, a virtual machine with the same configuration will be pulled up on the target host according to the configuration of the source host, and then the memory and device status will be transferred. If the memory management methods of the source host and the target host are different, the configuration of the source host cannot be used to directly pull up a virtual machine with the same configuration on the target host (memory allocation will fail), and virtualization cannot be performed. Machine memory and device state migration. [0003] For the above-mentioned problem that the hot migration of the virtual machine cannot be performed due to different memory management methods on different host machines, ...
