The invention belongs to the technical field of virtual computer environments and particularly relates to a virtual device generating and deploying method. Automatic virtual device generating and deploying are achieved by disintegrating the complete virtual machine image used by a virtual device into a basic substrate and a business device. The method includes the steps of firstly, deploying a virtual computing environment, deploying a physical host, and deploying a management server; secondly, under the support of the virtual computing environment, realizing virtual device generating and deploying through virtual device modules, and respectively setting virtual device modules including a universal template database, a device library, a device generating container, a device assembling container and an executing unit; thirdly, using a front-end user interface to create and generating the virtual device; fourthly, when the virtual device saved in the virtual device library is applied in the virtual computing environment, deploying the virtual device through the front-end user interface. The method has the advantages that the problems that application software submitting, deploying and configuring are difficult and time consuming are solved, the problem that the virtual device in the existing commercial technology is excessively large in size and difficult in issuing, and centralized application issuing, zero configuration deploying and fast issuing can be achieved.
