Abstract
A virtual machine monitoring method used in a virtual machine monitoring system is provided. The virtual machine monitoring method includes retrieving a hypercall transmitted from one of a plurality of virtual machines to a hypervisor of a virtual machine monitoring system, wherein the hypercall is used for establishing a channel between a source virtual machine and a target virtual machine. A central control virtual machine ID information in the hypervisor is retrieved. A type of the channel established by the hypercall is determined according to the central control virtual machine ID information and channel-establishing information corresponding to the hypercall. When the channel is a private channel that is not related to a central control virtual machine of the virtual machines, a security module is used to monitor the private channel.
