Abstract
A computer-implemented hypervisor system and method comprises utilizing the hypervisor system, which comprises a privileged domain (PD) and a guest domain (GD). The PD is an instance of a virtual machine that has direct access to hardware devices. The PD comprises a back-end interface for communicating with other GDs. The GD is an instance of a virtual machine that does not have direct access to hardware devices, and comprises a front-end interface for communicating with the PD and communicates only packets with the PD. On the GD, and in an initialization stage of the front-end interface, the system allocates a predefined number of packet data entries for storing packet data, allocates the predefined number of grant table entries, each comprising a grant table id. During the initialization stage, each grant table entry is bound with a packet data entry.
