Novel tools and techniques are provided for implementing a virtualization congestion control framework. In one aspect, a method might include a hypervisor assigning application resources of a virtual machine (“VM”), which operates on a host computing system, with maximum allowable settings to each software application to be executed on the VM. The hypervisor or an orchestrator might determine a running mode of the host computing system, and might execute the software application(s) using running mode attributes of the determined running mode. The hypervisor or the orchestrator might monitor application resource utilization, and, based on a determination that application resource utilization has changed, might modify allocation of application resources to each of the software application(s). In some cases, the hypervisor or the orchestrator might monitor for mass congestion indicators, and, based on a determination that a mass congestion indicator is present, might modify the running mode of the host computing system.
