A GPU virtualization technology-based video memory resource allocation method, device and equipment, the method comprising: obtaining video memory information of each virtual machine, the video memory information comprising a current remaining video memory space size of a main virtual machine and a video memory utilization rate of a guest virtual machine; determining whether a video memory allocation condition is met or not according to the video memory utilization rate; and if the video memory allocation condition is met and the size of the current residual video memory space of the main virtual machine is greater than a residual video memory space threshold, dividing the video memory space of the target value from the main virtual machine, and allocating the video memory space to the guest virtual machine meeting the video memory allocation condition. According to the method, for the use of the video memory space of the virtual machine, the video memory utilization rate of the guest virtual machine is dynam
