With the popularity of the cloud computing

the virtualization technology is becoming more and more important. However

a variety of different virtualization products have been emerging endlessly

so the unified management of different virtualization technologies has been increasingly more important. Building abstraction layer based on different virtualization systems is a method to manage heterogeneous virtualization resources. The shielding Iaa S platform management bottom layer of the resource abstraction layer solves the differences of the infrastructures and provides the consistent management interface. Under its management

heterogeneous virtual resources can be regarded as the same management interface resources and can be uniformly scheduled and allocated. Some virtual computing platforms are governed based on a same management platform by the abstraction layer

so virtual resource views are unified and the resource management becomes more convenient. First of all

a resource abstraction layer system design in the paper is presented; then introduces the cooperation of each submodule to complete the management of different virtualization system; the detailed process of the virtual machine resource application is given.
