摘要： 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.

摘要： This invention provides a method and an apparatus for determining a rendering duration. An audio/video recording system is used for recording an audio bit stream and a video bit stream. The audio bit stream includes a plurality of audio frames. The video bit stream includes N video frames. According to this invention, the rendering durations of the first and the last video frames are determined based on the moments when the system starts to record the audio frames and the video frames. According to this invention, when the (i+1)th video frame through the (i+NL)th video frame are lost, the rendering duration of the ith video frame is determined based on NL. According to this invention, when the system receives a command of synchronization correction for the ith video frame, the rendering duration of the ith video frame is determined based on a correction value.
