Abstract
This application discloses a computing system having a virtual machine and a host program that communicate via a virtual interface. The virtual machine can generate a data packet for transmission to the host program via the virtual interface. The virtual machine can receive a saturation signal generated by a virtual interface driver in the virtual interface. The virtual interface driver can be configured to populate a virtual buffer in the virtual interface with the data packet. The virtual machine can determine an availability of resources in the virtual buffer to store the data packet based, at least in part, on the saturation signal, and selectively stall transmission of the data packet to the host program based, at least in part, on the saturation signal. The host program can bypass a hypervisor in the computing system to directly access the virtual buffer in the virtual interface.
