Cloud-computing virtual machine management platform system

A cloud-computing virtual machine management platform system relates to the technical field of software. The system comprises a user interface layer, a core management layer, a virtualization layer and a material resource layer; the user interface layer comprises virtual machine state information, template state information and a service application entrance; the core management layer includes mirror image template library management, mirror image template scheduling, virtual machine instantiation, virtual machine state monitoring, resource dynamic adjustment and load balancing realization; the virtualization layer virtualizes material resources, and unifies discrete hardware resources into a platform capable of dynamic sharing; and the material resource layer comprises a server, a memory device and a network device. The cloud-computing virtual machine management platform system improves the speed of a virtual machine disposition mechanism, and ensures the migration safety of virtual machines.
