The invention discloses a virtual machine live migration method and device, a storage medium and electronic equipment. Comprising the following steps: determining occupation values of a plurality of threads of a single virtual machine occupying a first exchange partition of a source physical machine to which the threads belong; when the occupancy value is greater than an occupancy threshold value, obtaining a total region value and a region idle value of the first exchange partition and a memory idle value of a physical memory; taking the difference between the area total value and the area idle value as the total occupancy value of the first exchange partition, and creating a second exchange partition when the total occupancy value is smaller than the memory idle value; and when the plurality of virtual machines are subjected to live migration, storing the first virtual machine data in the first exchange partition into the physical memory for migration, storing the second virtual machine data in the physical
