Novel tools and techniques for implementing a virtualization congestion control framework. In one aspect, an orchestrator might be provided within a virtual machine environment context in order to provide two-way communications between the virtual machine (“VM”) and one or more applications running on one or more virtual machines in the VM environment in order to control congestion in hardware resource usage, perhaps using a congestion API. In some embodiments, the two-way communications might include communications from the VM to the applications including maximum hardware resources and current resources, and might further include communications from the applications to the VM including pre-congestion notifications and low-utilization notifications. According to some embodiments, a buffer utilization feedback may be provided between the VM and the applications, said buffer utilization feedback allowing the applications to control pushback mechanisms, said pushback mechanisms including mechanisms for pushing back on or decreasing hardware resource usage.
