IaaS management platform and method

The invention discloses an IaaS management platform and method. The platform comprises a network reinforcement unit and a service unit in a virtual machine monitor. The network reinforcement unit is used to intercept an autonomous network configuration operation when the network reinforcement unit detects that the operation is executed by a client domain virtual machine user, and sends a page table modification service request to the service unit. The service unit is used to receive the page table modification service request sent by the network reinforcement unit, determine a system calling table according to the page table modification service request, modify a page table item operation authority of the network reinforcement unit corresponding to the system calling table, and send a page table modification service response instruction to the network reinforcement unit. The network reinforcement unit is also used to process the intercepted autonomous network configuration operation of the client domain virtu
